Appendix B - More on Presta Valve Locknuts, aka Valve Rings

Introduction 

Obviously, just about anyone would read an essay of almost any length about Presta valve locknuts, aka valve rings. Even so, I deferred last week to the presumed minority of souls who are intimidated by vast tracts of text, and I actually shortened (!) my post. I achieved this via two means: a) moving a tangential discussion of tubeless setup to an appendix, and b) saving a second digression for this week. So, as a counterpoint to last week’s post and its Appendix A, I herein provide Appendix B. I had originally intended to use this post to present my brother’s input on the topic and my response—and I will get to that. But first, I’ve already received lots of reactions to the first post and I’ll tackle those now.

Feedback on the first post

It goes without saying that my first essay on valve locknuts generated immediate and impassioned responses. First was this commentary (from Anonymous) below the post itself:

Deep analysis of an important topic. I have shared with all my friends. I expect to have fewer of them shortly.

Next came a written apology from M—, who started this whole thing 13 years ago when (as recalled in last week’s post) he called my use of valve locknuts “a sign of novice nerd-dom.” In an email last Thursday he announced that he’d read my last post in its entirety—something he almost never does, but in this case, as he explained, his wife “was watching some PBS program about British royals so I had some idle time.” He went on to say, “ I apologize for the stinging remark about your moronic use of stem nuts.  I can be frightfully insensitive at times.” (And as you have seen, I can be frightfully moronic.)

Subsequently another member of our bike club, K—, emailed the group, “Dana, thanks for sharing the valve rings / valve stem nuts article. We chatted about it at the Sibley stop on today’s ride, then lo and behold what should B— spot but a valve ring in the wild!

I replied to K— and the group, “I hope somebody grabbed it for his or her stash, or maybe even valve, or at least to clean up litter,” to which K responded, “I did not grab it Dana. One of my valve stems ( the wheel in the picture) was unthreaded and the other … had a valve stem ring on it already! Also, I think the group’s feeling was that this was now a ‘wild’ valve stem ring, and it was best to leave it to its hard-earned freedom.” Fair enough!

That same day, another teammate, D—, wrote, “After reading your post I added valve rings and caps on the short stems in the low profile Mavic MA40 wheels on my 1970s Frejus — in support of ultimate loser dorkitude — certified M-approved.”

Look at that! Actual valve caps! Seeing those certainly throws you for a loop, don’t it? Unlike valve locknuts, these caps are so universally eschewed that actually seeing one is as unexpected as seeing a dog washing itself, or viewing an AI-rendered drawing of a person with three arms, or encountering a schoolgirl with sideburns (though none of those exemplifies dorkitude, I hasten to add). The first photo of this post, of the capped crooked valve ... ugh. Just ugh.

The next response was from L—, who inquired, “OK, but what about a bling driven setup where I have the nut and the cap because they are from Hope and bronze anodized to match my hubs?” He included these two photos:

I think in the case of extreme bling, a special dispensation should be granted. Nothing wrong with a little flair. L— has mentioned that he used to mountain bike in Hope, a place in Derbyshire near Sheffield (though Hope is also, confusingly, a manufacturing company in Barnoldswick, Lancashire). I shall hereafter always think of L— as The Man From Hope. (Well, okay, the other man from Hope.) Now, I’ll bet I know just what you’re thinking: wouldn’t one of those amazing gold anodized valve caps make a fine addition to M—’s collection? L—, if by some chance you’re reading this: you have been warned.

And now, I shall move on to my original topic, the invaluable input on valve rings from my brother. (If more responses to my previous post come rolling in, I’ll have to address them in another appendix or two.)

Uncle Bryan weighs in

When I originally solicited opinions about valve locknuts via email, I really wanted my brother Geoff to chime in. After all, it was my impasse with him that got this whole debate going, 36 years ago. Plus, he’s one of the best bike mechanics I know; his nickname when he was the mechanic for the Cal Poly Wheelmen was “Dr. Shimano.” I was known, to the members of his team and mine, as his loyal sidekick, Tecnova, named after the really shitty Panaracer tires that tended to come on Japanese road bikes in those days.

A note on those tires: I spelled the name wrong in a previous post. I’d put “Technova” but just learned it’s actually spelled “Tecnova.” So sue me. Anyway, here is a photo. Just look at how shitty they are:

This  probably won’t surprise you, but I had ChatGPT help me chase that down that photo. Have you ever noticed how when the chatbot is done servicing your request it always suggests something else it could do? It just doesn’t want to let go. It should be called ClingGPT. In this case it asked if I wanted it to provide a “high-resolution, clean copy” of the tire photo for me. I said sure. Here’s what it created:

Look at that! It bears no resemblance to the real tire! John Keats would be turning in his grave. (He’s the one who wrote, “Beauty is truth, truth beauty.”) What’s kind of frightening is that ChatGPT could have corrected my spelling but instead reinforced it. It even claimed that there’s disagreement about “Technova” vs. “Tecnova” and cites this very blog as precedent for “Technova,” even though the GPT knows I’m albertnet’s author. When AI ultimately replaces human companionship, nobody will ever be kept honest again. But they’ll be so cozy and satisfied with their sycophantic digital pals!

OMG, where was I? Oh, yeah, I’d reached out to Dr. Shimano for input on valve rings. Alas, I couldn’t get his attention, but I did get a nice response from his evil twin, Uncle Bryan. (Is Bryan evil? No, of course not, he’s just Geoff’s twin. But “evil twin” has such a nice ring to it! In reality “evil” applies instead to Geoff, because he is known to all his nieces and nephews as “Evil Uncle Geoff,” just as I’m known as “Evil Uncle Dana.” And are Geoff and I evil? Yes, definitely. Now, moving on to the “Uncle” bit, it just seems to me that as my brothers and I age and try to embody the gravitas we’re expected to have as full-on mature adults, we should have some kind of honorific to extend and embellish our names. I would enjoy being called Captain Dana, or Master Dana, or even Lord Dana, but of course I haven’t earned any of these. In certain contexts I get to be Coach Dana, but that doesn’t transfer very well to my everyday life, so I generally have to settle for Uncle Dana. Somehow among my brothers and me this “easy honorific” has become completely standard, to where it’s actually rare to leave off the “Uncle,” even if we’re just talking to each other without a niece or nephew in earshot.)

With no further ado, here is Uncle Bryan’s commentary.

First, the against. Do they really work? It’s hard to say if they work or not without knowing what it is they are supposed to do. I’m not prepared to answer that question at the moment. So the answer is yes, I think they do work, so that’s not really an against, except that some believe that they don’t really work. I’ll address that conundrum later. 

The other against that I can think of: weight. They add weight to the bike. I don’t care about that. The weight is negligible and if I were concerned about weight, well... there are other areas where that could be addressed with orders of magnitude of difference. Didn’t you once thread many valve rings on an opponent’s bike to add weight and annoy? And also fill his frame tubes with ball bearings? And was this the kid who would stop what he was doing every few minutes just to walk over to his bike and heft it, just to remind himself how light it was? At the Joke on the Hill? 

There is one real problem with valve rings that I can think of, though, and that’s that they often come loose. It seems to me that they rattle and annoy, though now I’m so deaf that I can’t hear if they are rattling, so maybe they don’t ... but I remember that they used to, but then again can I really remember anything? Am I just imagining all this? It’s like Dad when his front derailleur would be rubbing and driving us all mad but we were too shy to mention it most of the time. I did see a front derailleur that was ground almost all the way through, leaving this knife edge in the metal... was that Dad’s? He couldn’t have ridden enough to do that, could he have? No, it was Dad’s! I can totally see it in my memory! But then there’s that memory problem again... No, I’m sure it was! Now the tables have turned, of course. I was riding with [his son] John, maybe even when we did the STP, and he pointed out that my bike was making a clicking or ticking or popping sound, mostly in first gear, or at least in the lower gears where the tension was high and the wind noise low. I know it does this but can’t figure out what it is, so I just pretend it’s not happening. If I do that I pretty much can’t hear it anyway. I’m just too tired to care, and what can I do? So maybe the valve rings do rattle, and maybe that’s a problem, but not for me. The other problem with their coming loose is that they’re probably not doing what they’re supposed to be doing, whatever that is, if they’re loose. 

So what are the benefits of valve rings? Let’s see, I know there are some benefits, some reason that I “like” them, or at least use them. Okay, firstly, they keep the stem from disappearing in the rim hole when you shove the pump head on it. That’s handy, but of course there’s the down side that if you don’t shove the stem into the tire body before inflation you might end up with the tube next to the stem lifting the tire beads and blowing the tire off the rim as you inflate, and it’s hard to shove the stem in there with a valve ring blocking the way. I seem to remember that happening like fifty years ago, but I don’t think it happens anymore, or maybe it was all in my imagination, or a theory as to why the 500 PSI air compressor at the gas station blew my tire up in two seconds and the explosion right next to my head ruined my hearing. Either way I’m going with the rings. 

The other thing it does that I can think of is that it keeps the stem perpendicular to the rim, which is of utmost importance. There’s nothing dorkier than a valve stem that’s all cockeyed. I’m sure we used to argue that it was a safety issue as well, but then we argued all sorts of stupid stuff. And if you’ve got the tube misaligned with the tire too much the valve ring just isn’t going to save you, it can only do so much. 

Now it seems that there’s more... oh yes, if you don’t have a valve ring it’s like the stem is naked and you can see past it into its more modest regions, that place where it’s not polite to look. If the rim has a big valve hole this problem is even worse, and it also exacerbates the issue with the stem’s angle to the rim. Maybe back in the day we’d use a valve ring to cover up the fact that the rim was made for Schrader valves (or worse, reamed out for Schrader, by you!) and by extension you were a loser. You may as well have steel rims. So yeah, a valve ring can do that. It also looks like it’s protecting the stem somehow, maybe from getting broken off if it got bent too far in one direction. I don’t know how it would do that, but that’s the feel it gives. It just looks better, okay? Like a fork crown with a Dura-Ace brake on it, not naked; clothed, armored, even. 

One more thing... it’s just more stuff, more intricate parts, more little things to make the bike cool. Like those caps we’d solder on the cables, or cable goodies, or the Shark fin, or the little sack for the Suntour... what was that, power cam? Yeah, the power cam brake. I actually feel the same way about presta valve caps, but I guess valve caps are another blog post—probably your next one, in fact! 

My responses

So, starting with Bryan’s first question—what are these locknuts even for?—I think it’s remarkable that he even asked. I will assert (at the risk of antagonizing some readers) that most people form opinions without really bothering with the step of wondering. Instead they quickly discern what position their tribe has taken, and unquestioningly align with it.

Bryan is right, of course: valve locknuts do indeed hold the valve straight, though any competent mechanic should be able to get this right, and the crooked valve problem is more with Schrader valves on low-pressure tires because these valves are common among cheap-ass commuting bikes that get very little maintenance. I am convinced—and I’m happy to argue with you about it—that riding your crappy commuting bike with underinflated tires causes the valves to gradually get pulled crooked. So if anything, more Schrader valves should have locknuts. (I have only seen one such tube.)

Bryan’s memory of my threading “many valve rings on an opponent’s bike” is accurate; as described here, I once stacked like ten of these locknuts on each of my opponent’s valves. My opponent was of course was our evil brother Geoff; this was part our valve locknut war. But filling a frame tube with ball bearings … that wasn’t me. That was this kind of annoying guy I worked with at The Spoke, or (as my brothers called it) The Joke. It wasn’t The Joke on the Hill, though; it was the lame Joke in the Table Mesa Center. The Hill was the college community and that was The Joke’s flagship shop. Not only was “my” shop the lesser one, but I wasn’t even an hourly employee … I was just a lowly assembler, paid by the bike. My brothers scorned me because the shop we admired (and that we eventually all worked at) was the High Wheeler, or Thigh Feeler as we called it. It didn’t matter that my brothers didn’t even work there at the time—they could still mock me for my lesser affiliation. (As you can see, these twisted parasocial relationships actually predate social media.)

I distinctly remember the guy at the Joke whom Bryan referred to. He looked exactly like Jahn, the creepy, developmentally arrested ringleader of eerie children in the 1966 “Star Trek” episode “Miri.” Jahn, as you’ll surely recall, led the kids in calling the Enterprise crew “grups” and in ultimately attacking them, chanting, “Bonk, bonk on the head!” So uncanny was this bike shop guy’s resemblance, I felt nervous working around him. (I don’t remember his name, not that I’d give it to you anyway.) Where my memory fails is that this guy was either the perp or the victim of the ball bearing prank and doggone it, I just can’t remember which.

Anyway, the story is, somebody at the Joke (possibly the Jahn lookalike) had a beautiful Mercian road bike made with Reynolds 753 tubing, which was a really big deal in those days (this being around 1982). The thinnest part of the tubing wall was just 0.4 mm thick, and a mechanic with strong hands could actually see the tube compress if he pushed hard enough on it with his thumbs (or so it was said). This frame was built up with the lightest stuff, even the actual Campagnolo Super Record pedals with the titanium spindles (as opposed to the cheaper steel-spindle Superleggeri most of us had). Despite belonging to the employee, this bike was always on prominent display on the showroom floor. Its owner, who wasn’t even much of a cyclist, was in the habit of walking over to pick it up end enjoy how light it was. He did this multiple times a day and it drove the rest of us nuts. So finally the perp (possibly the Jahn-lookalike) waited until the bike’s owner went to lunch and then pulled out the bike’s seatpost, and filled the entire seat tube with ball bearings. He put the post back in and then we all went back to our posts and waited for the owner to get back from lunch and lift his bike again. When he did, he just about had a heart attack, and the rest of us almost died laughing.

Moving on to Bryan’s memory of our dad’s front derailleur rubbing constantly to the point it was destroyed … is that accurate? 100%! I remember it very well, because I felt so lame about being too timid to bring it to our dad’s attention. That’s how little rapport we had with the guy. His reward for being so aloof and unapproachable is that not only did the chain eventually grind all the way through the derailleur cage, turning the remaining piece into practically a blade, but eventually when he went to shift, that scalpel-like protuberance peeled the side plate of his chain like a damn can opener, as though the front derailleur had taken revenge! No, I wasn’t there when this happened, but for some reason my dad loved telling people all about it. The way he regaled his friends, colleagues, and probably even complete strangers, it was like he thought it a heroic tale!

Regarding Bryan’s next observation, “if you don’t have a valve ring it’s like the stem is naked and you can see past it into its more modest regions, that place where it’s not polite to look,” this is beautiful, deathless prose and I have nothing to add.

“Like a fork crown with a Dura Ace brake on it, not naked, clothed, armored, even.” He’s referring to the modern fork of a bike with disc brakes, so the fork crown is totally naked, no cool-looking brake caliper like we’re used to seeing.

Now, the Power Cam brake he mentions was a total disaster invented by Suntour. It really should have been featured in road.cc magazine’s feature on Design Blunders. The brake had these little rollers and a specially shaped cam that was supposed to give you great braking power without tight pad/rim tolerances. There were three main problems with this. One: it was a pain in the ass to adjust properly given the variety in rim widths and the weirdly shaped cam. Two: as the pads wore down, the wrong part of the cam would engage, so the brake worked poorly. Three: the brake was mounted to the underside of the chainstays (supposedly because they flexed less than the seat stays), so it tended to get packed with mud, which would gum up the cam rollers and foul up the brake further. In response to this third issue, a company called Overland made an after-market ballistic nylon jacket for the entire assembly. This was pretty hokey, although arguably more important than a valve locknut and certainly more beneficial than a valve cap. Evidenly Bryan actually liked this little jacket; I guess he just had a weakness for all the little bits you could add to bikes.

Speaking of little bits, he misremembers soldering little caps on the end of cables. There were little caps, which fell into the category of accessory we called “cable goodies” at the bike shop (which category also included little rubber donuts that a brake cable gets threaded through to stop it from dinging on the frame tube). We did solder the ends of cables, with a little torch, which I will never forget because one day Bryan let a blob of molten solder drop right off the end of a cable onto the head mechanic’s bare toe, causing him to howl such a powerful stream of profanities to make a man’s blood run cold. But the caps Bryan is evidently recalling were these cool little cable caps that Shimano included that were actually made of solder, so all you had to do was hold a flame to them. Clever, huh? And then there were the little aluminum caps you could just crimp on there, still prevalent today, which we called cable titties.

And the Shank Fin? That was a chainstay protector that had a little fin on the front to keep your chain from getting sucked into the tire. I recall these fins working pretty well and I don’t know why they no longer exist, other than to say the chain is more prone to getting sucked up from the bottom. A skilled mountain biker can hear and/or feel when this is happening and quickly backpedal, just a quarter turn, to release the chain; with e-bikes there’s no such feedback and the chain ends up breaking, which is why you see e-bikers on the side of the trail peering into their smartphones to try (usually in vain) to learn how to fix a broken chain. O brave new world!

Well, I hope you’ve enjoyed this plunge into bike arcana. I know I strayed pretty far from the point here, but isn’t being beside the point kind of the point? (It is for me, anyway...)

Presta Valve Locknuts, aka Valve Rings

Introduction

As you’ll surely agree, this post is long overdue. It stems from my post “10 Fascinating Facts About Inner Tubes” that I wrote over 13 years ago. Fact #4, “Valves can fuel sibling rivalry,” described the war I fought with my brother Geoff over Presta valve locknuts, aka valve rings:

We had an ongoing disagreement about the usefulness of valve rings. I argued that they helped you keep the valve straight, helped you get the pump chuck on there, and enabled you to ride a flat without the tube bunching up around the valve. He argued that … wait a second, this is my blog, I’m not going to bother giving his silly arguments! He can comment on this post if he wants his position articulated.

Geoff was forever stealing the rings from my bike’s valves to deprive me of them. I had to keep spare valve rings on me in case I discovered his treachery too late, like during a ride. In retaliation I was forever putting rings on his bike’s valves. There was a lot of cussing.

(There’s more to that story, which you can find here.)

In response to that post, M—, a guy on my road cycling club, who raced with Greg LeMond back in the day and who has always been our club’s Obi Wan Kenobi, replied, “Valve rings, as you call them, were always the sign of novice nerd-dom, like crank bolt dust caps. Your brother was right.” This really stung, since a) it came from our guru, and b) I never used crank bolt dust caps, because I knew better, but somehow I didn’t know better about these locknuts. (For more on crank bolts, click here.) From that day forward I mended my ways and stopped using valve locknuts. (I did keep one in my toolkit for roadside repairs.)

End of story, right? Well, not so fast. In cycling circles, widespread debate about Presta valve locknuts still bubbles up from time to time and has done so for decades. It’s the perfect hot button issue to tackle on albertnet because it gets people bickering good-naturedly without ruining friendships or landing me on either side of the currently raging culture war. So I decided to poll the members of my bike club on the topic, along with a couple other cycling pals and my brother, and describe in these pages the current Presta valve locknut zeitgeist.

The bike team weighs in

Curiously, more East Bay Velo Club members came out against valve locknuts than in favor, though I suspect more of my teammates use them than not, as I shall get into. I know with certainty that one of the “con” votes was from a guy I ride with all the time who does use them, as he told me himself … but that’s not what he put in writing.

Trigger warning: this is not a short post. If you have attention span issues, I recommend you either a) visit this page instead, b) request a vlog version of this post, or c) print it out and store it on your toilet tank to work through over time.

Okay, here’s what my bike club had to say:

1. I’m a nay on the ring. Need to reduce weight as much as possible. Plus, it just slows you down when having to change tubes—yes, I have still not gone tubeless. And last, if you have them on they loosen up and rattle...

2. Tubeless all day. Pro. [This is a tacit “for” vote … more on this later.]

3. I save them all for making bike bling bracelets, necklaces, etc. Still they continue to pile up. Need any? [He included these photos:]

4. Con. They work their way lose and rattle and it’s annoying.

5. Perhaps  we can add the little cap to the fray. That said, I once had to change a tube with a short stem in a deeper wheel, and it was impossible to insert the pump [chuck] as there was very little length left outside. I have since bought a screw on type, but still put in the nut unless it is a Michelin tube or TPU… [Not clear what “a screw on type” means here but I suspect either a screw-on pump chuck—more on this later—or a valve extender, which is a whole other topic. More to come on TPUs.]

6. I am very much on the pro side of piston rings, which sound like they should be mentioned in the same breath as valve rings, but which of course are entirely unrelated.

7. [From M—] Growing up riding on sew-ups (“tubulars” to youngsters) I never saw a stem nut. I don’t use them on clinchers either but could see how they’d be helpful for some people. The combination of unnecessarily long valve stems and ham-handed pump technique puts a lot of leverage on the stems, which I’ve seen damaged. This probably applies to pumps that attach directly to the stem vs. ones with a short, flexible hose. Both valve caps and stem nuts are largely useless. However, as collectors’ items, the former are vastly superior. [He included this photo of his prized valve cap collection.]

8. Since I’ve been a tubeless guy for 12 or more years, I can’t really see life without valve rings. That said, I recall also liking [pre-tubeless] to have them on tubes cause they frankly made it easier to get the pump chuck seated on to the valve before pumping the tire. So, for those guys who are against valve rings, tell them to SUCK IT!

9. I was talking about your forthcoming post on valve stem nuts on my ride today and someone pointed out that some of these modern TPU tubes don’t even have threads on the stem. No Nuts! 

My responses

There is so much to explain and respond to here, I feel like a kid in a candy shop, or more accurately an ectomorph with a pet tapeworm at an all-u-can-eat buffet.

First off, the locknuts do make it easier to get an old-school pump chuck on there because the valve doesn’t get shoved down into the tube. Is it the case that a valve that’s pulled out too much can interfere with seating the tire and cause it to blow off the rim? Yeah, that can happen. But it’s also the case that cramming a chuck on lockring-less valve can damage the tube, because the valve can get torqued around and, worse case, the tube rips at the valve. So there’s no free lunch, really, with traditional pump chucks.

That’s where M—’s input comes in, about the modern mini-pumps with the short, flexible hose. Not only do these not torque the valve around, but because the chuck isn’t shoved on there but instead just screws on (using the same valve threads that the locknut uses), there’s no need for the locknut. But the screw-on chucks have a downside, which is that they tend to unscrew an under-tightened valve core, so when you finish unscrewing the chuck and pull it off, the core comes with it and—WHOOSH!—all the air escapes. And unless you have a valve core tool in your kit, you’re pretty much screwed. I see this several times per season when coaching high schoolers. It also happened to me recently on El Toyonal, a road that is closed to cars. I’d have been stranded except I was able to screw the core in far enough with my fingers to make it (sort of) work. I couldn’t believe I managed that. It felt like an 80-yard Hail Mary pass (and as you can imagine I am useless at football).

Any argument about saving weight is a joke (perhaps literally). This is a case, I think, of the person supplying a merely ostensible reason because he doesn’t actually know why he does what he does. (Or she.) I don’t own a scale sensitive enough to weigh a valve locknut. I suppose I could gather up all the ones I own (probably at least twenty, spread out over several boxes, toolboxes, the little nipple holder on my truing stand, and elsewhere) and take the average, but I can’t be bothered. This tiny locknut couldn’t even weigh a gram. If you want to save that much weight, just blow your nose before you ride, or alter your diet. Or better yet, to M—’s point about unnecessarily long valve stems, get the ones that are only just long enough for your aero rims … I see a lot of “stem inflation” (pun intended, sorry) and I don’t like it. The valves look like they’re aroused.

Let’s proceed, then, to the most common criticism of valve locknuts: they come loose and rattle. This is sort of a legitimate complaint. Why only sort of? Because not only is it not always true, many cyclists will tell you that the opposite is true: that part of the purpose of the lockring is to prevent the valve itself from rattling. So which is it? I think this has everything to do with your specific setup. I used valve locknuts on the cheapy Araya rims that came with my Miyata 310; on the Super Champion Gentleman rims I had on my Mercian; on the Wolber 58s I use for my commuting bike; on the Mavic MA-40s I trained on for many years; on the 16-spoke Shimano aero wheels that I had briefly before they disintegrated; and on both pairs of my Mavic Ksyriums. In zero of these cases did the locknut rattle. And I didn’t tighten these locknuts with pliers like an idiot (though a friend of mine did this in junior high and thus couldn’t fix a flat out on the road once and had to call his mommy). Are my fingers possibly stronger than those of the people whose valve locknuts rattle? Possibly, due to all the years I worked in bike shops. (As we always liked to tell people, “Bicycle mechanic bleed on the inside.”)

So if you, gentle reader, were to install valve locknuts, would they rattle? I’m gonna say probably not. As I look back on all the hundreds, perhaps thousands of cyclists I’ve ridden with, I honestly cannot remember a single instance of valve lockrings rattling. This isn’t because I have a faulty memory; after all, I remember the kid in junior high I just mentioned who’d over-tightened his lockrings, and that was over forty years ago. Meanwhile, I distinctly remember the converse: a valve rattling, which bothered several of us on a ride 16 years ago. It couldn’t possibly have been a locknut because the valve was on a sew-up (tubular) tire. I have photographic proof. Look:

This was during the 2009 Sierra Century (details here). Mark got so frustrated with the rattling he stopped at a rest stop and accepted assistance from the staffer you see above, who was beyond stoked at being able to help, even if that only meant holding Mark’s bike. I’m pretty sure she’d fallen in love.

Okay, you’ve probably stumbled onto the theory that I’m just deaf and/or willing to ignore an annoying noise. I will concede that the latter may be true. I know I mentioned mere moments ago being bothered by Mark’s rattling valve, but to be more specific, it was his complaining of the rattling that actually bothered me. My own bikes have made various noises over the years and yes, I’ve managed to tune them out. Humans are harder to ignore. I was once accosted repeatedly during a ride by my pal T—, who complained incessantly about my pump rattling until I finally did something about it. And I’ve had people complain about my wheels making some kind of noise that I always took as a cry for help (the noise of the wheel, not my friends) but that I figured would take care of itself when the wheel inevitably died. My friend C— often apologizes for the noises his bike makes, and almost invariably I don’t even know what he’s talking about.

(There was one notable exception. One day back in 2007, his bike was making an awful creaking noise that seemed to get progressively worse, and he apologized repeatedly. I have to confess, I  really was getting annoyed, I mean the noise was that bad. Finally I turned off to head up Lomas Cantadas, just to get away from the din, but to my horror the noise persisted. It wasn’t C—’s bike after all, it was mine … my fricking frame was broken! The seat tube had cracked down near the front derailleur, and right about at the turnoff to South Park Drive it sheared completely in two. By the time I got home the noise had grown to the sound of Satan eating a steel garbage can.)

If you’re using a Presta tube in a rim drilled for Schrader, you need more than a locknut—you need a rim grommet, which looks like this:

I’ve used those and they absolutely require a locknut because more often than not, they pucker out like a hemorrhoid which is really gross to look at but is well hidden by the locknut.

Now, if you’ve been paying attention, first off congratulations, and second, you’re probably wondering about my assertion that more of my teammates use valve locknuts than not, despite what a majority of them have indicated in my email survey. This is because I’d guess over half of my teammates are now running tubeless, which setup practically requires lockrings. (It’s not 100%—as I’ll get to—but they certainly help.) So shouldn’t the modern debate be about whether to run tubeless tires or not? Isn’t that where the rubber meets the road? (Sorry, couldn’t resist.) But the tubeless-or-not debate is actually pointless, for the simple reason that this matter is entirely cut-and-dried. There is an obvious right answer, and I have it, and I shall give it to you.

But first, I have just one other tidbit from the reader comments to address, which is piston rings. I found that aside so comical, I read it out loud to my wife. She is a curious sort (and a recovering journalist) and asked, “What are piston rings?” So I started to mansplain them to her, and about a minute in I paused and asked, “Are you actually interested in this?” She replied, “No, I’ve stopped listening. I was only wondering if they were part of a bicycle.” I assured her they weren’t but that they were absolutely integral to the function of a car engine. She asked, “Do all males know what piston rings do?” I said yes, of course. “Why?” she asked. I asserted that all males find such matters intrinsically fascinating. (If you are a male reader and disagree, please set me straight via a comment below.)

So, there is a lively debate, online and IRL, about tubeless vs. tubes, and many of my pals have weighed in during our rides over the last five or more years. Until recently I was a bystander in this because my wheels, though insanely cool, couldn’t accommodate tubeless tires anyway. Well, I finally came into some tubeless-ready wheels, contemplated the matter for about thirty seconds, decided to ignore all the horror stories about how hard road tubeless tires are to mount, pulled the tubes out, stuck the valves in, dumped some goo in the tires, reseated and inflated them, and ditched those inner tubes forever (unless I have a rude awakening ahead of me in which case I’ll blog all about that when the time comes).

Here is the point: if you’ve made it this far into this post, it’s almost a given you’ve spent thousands of dollars on a bicycle. So you want that bicycle to ride as beautifully as possible, right? Tubeless gets you there. Nothing else matters. So don’t give me any song and dance about maintenance, punctures, mess, ease of installation, whatever. What is your bike for: to ride, or to fix?

Here’s an analogy: suppose you’re a happily married man, with all the children you want (even if—or perhaps especially if—that number is zero), and you’ve just gotten a vasectomy. You’ve had the follow-up semen sample tested, it came back negative, and the doctor has just left you a voicemail saying, “You can have all the unprotected sex you want.” Now, would you continue using condoms? “Well, I’m used to them, and it’s less messy,” no sane husband would ever say. So it is with tubeless: you’ve gotten rid of a pesky bit of rubber that no longer has any place in your life. The road feel is better with tubeless, cornering is better, and rolling resistance is lower. (And to the weight weenies calling for skipping locknuts on your inner tube valves to save weight, get real: I knocked a quarter pound off the weight of my bike by ditching the tubes. I only put an ounce of sealant in each tire; when it dries up I’ll add more, no biggie.)

So what about TPUs? In case you haven’t heard of them (I myself hadn’t until recently), these are tubes made of thermoplastic polyurethane instead of rubber or latex. This brings the weight down by about 20-30 grams vs. traditional tubes, while also offering lower rolling resistance. They’re also easier to mount. All this being said, they’re $20-30 each, and the special patch kit required is $8 or $10—both way pricier than standard, and needless to say pricier than that ounce of sealant. And yet, at the end of the day, the TPU setup is still heavier than tubeless and still doesn’t ride as well. To continue my vasectomy metaphor, they’re like fancy lambskin condoms … better, sure, but more expensive, and still unnecessary. And why don’t TPU tubes accommodate locknuts? Because, as you saw above, the valves aren’t ribbed (i.e., threaded) for anyone’s pleasure!

If you persist in arguing for inner tubes based on less hassle, etc. you need to accept that the tubeless technology is not the problem: you are. If you are serious about riding an excellent bicycle jolly well, mounting tubeless tires is just something you need to get good at, like typing and being organized and knowing how to scramble an egg (or, for the vegans among you, properly prepare tofu). Setting up tubeless is not that hard. Suck it up. I even have step-by-step instructions for you, here.

Okay, fine, there’s one non-trivial argument against tubeless tires, particularly for road bikes, which is the idea—not without anecdotal evidence—that the tire can blow off the rim. So here’s what to do. First, choose the right tire for your rims: if you have hookless rims, you need hookless-type tires. Consult the manufacturer’s compatibility charts to be sure you have the right combo. Then, read the recommended PSI for the tires you’re using, and for the rims you’re using. Go with whatever is lower. Still nervous? Use a fatter tire and go down another 10 PSI or so. Thousands of professional riders use this technology … it’s mature, it’s commonplace, and it’s arguably as safe as any other aspect of road cycling. All this being said, note that I’m just a blogger, not an industry expert, a certified accountant, an Internet influencer, or a medical doctor. Caveat emptor (translation: don’t sue me).

Now: can you run tubeless without valve locknuts? The conventional wisdom is that you cannot, because the locknut holds the valve firmly in place so it can make an airtight seal with the rim. In fact, ENVE claims that if you don’t use their special Pressure Relief Valve Stem Nut (PRVSN), your rim could actually explode. I doubt you need $5 PRSVNs, but I do recommend valve locknuts based on my own experience. (If you’re curious about what happens without them, see Appendix A. If you’re curious about other stuff, see Appendix B.)

This made me wonder: if tubeless basically requires locknuts, why didn’t my tubeless-ready valves come with them? Answer: they did, but the locknuts were just floating around loose in the box of accessories (reflectors, etc.) that my bike came with. Check it out: the locknuts are black to match my wheels. How cool is that?! I’d never seen (non-plastic) black valve locknuts in my life!

Synthesis

So what’s my ultimate verdict on valve locknuts? As follows:

• If you have a commuter bike with Presta valves, use the locknuts or not, at your whim
• If you have a backup “rain bike” that you mainly ride on the indoor trainer, you better be using noise-canceling headphones, in which case you can use locknuts or not, because who cares if they (or your valves) rattle?
• For your flagship road or mountain bike, run tubeless with locknuts, and if anybody makes fun of you, send them this blog post.

One more thing: do I ever hear valve locknuts rattling on wheels with tubeless tires? I’ll give you a hint: no. Still stumped? Here’s another hint: I don’t.

Appendix A

Tubeless-ready wheels came with my new bike, but the tires were mounted with tubes since it’s impossible to know how long a bike might sit around in a warehouse, its tires going flat (which could break the seal and cause sealant to ooze everywhere). So I dug through the bag of accessories (reflectors, a bell, owner’s manuals, etc.) and found the valves that came with the wheels. They didn’t have locknuts in the little bag, so I assumed locknuts weren’t necessary. (Obviously I could have installed some from my stash, but M—’s admonition about “novice nerd-dom” was still ringing in my ears, 13 years later.) Despite all the mythology I’d heard about setting up tubeless tires, I not only managed to get the tires to seal without lockrings, but did it with ease. My assumption, that the pressure inside the tire would hold the valves in place, seemed to pan out.

The problem is, not all seals are created equal, and tubeless-style valves (at least mine) do not have a round base. The rubber part that butts up against the rim is rectangular, as it’s designed to sit in the rim in a specific way, and if it gets twisted the seal is slightly compromised. I learned this on my fifth or sixth tubeless ride: before heading out, I topped up the air pressure, and when I removed the screw-on pump chuck from the valve, it put up a fight (as it often does) and must have twisted the valve. About 90 minutes into my ride the tire pressure had dropped to about 40 PSI, maybe less. I thought I could pump it up and get home, but as I mentioned before, halfway up El Toyonal the tire was again almost flat, and that’s when I had my mishap with the valve core.

So yeah, use locknuts with tubeless, to make sure the valve stays straight. The locknut also helps when you tighten down that valve core good and snug. (If you use a screw-on chuck and don’t have a valve core wrench, buy one immediately.)

From the Archives - My Front Derailleur Tragedy

Introduction

In some ways, 1995 was a tough year for me. After the beautiful freedom of the cross-country bike tour that had taken most of the previous year, I was hunkered down and working hard in a nowhere job at a consulting firm. During my recruitment with this company, knowing they’d smoke me right down to the filter if I let them, I insisted that I be eligible for overtime pay. Several of the workaholic engineers dragged me along with them into fifty-hour workweeks—and, being paid time-and-a-half while saving to buy a house, I was all too happy to oblige them. I managed very little work/life balance.

This meant, of course, that my racing bike was sorely neglected, in every way. I was riding only two or three days a week, and wasn’t taking the time to keep the poor bike tuned up. (It didn’t help that my 450-square-foot San Francisco apartment didn’t have anything like a garage, and though I still had a workbench whenever I needed one at the shop where I’d worked in college, that was across the Bay in Berkeley.) My body fared as badly as my bike. When I did ride, the sport felt like something I used to do. That’s the landscape for the sad tale that follows. (This was not a blog post, as those didn’t yet exist, but an excerpt from an email to my brother Geoff, on which I’d cc’d half a dozen friends).

My Front Der – May 11, 1995

I gotta tell you about my front der. (“Der” seems to be the new bike shop lingo for derailleur. I still prefer “mech,” which is what my favorite two Square Wheel colleagues, illegal immigrants from England, called them. Customers sure got confused.)

During a recent evening ride, I got a flat tire on the Golden Gate bridge. I wasn’t worried, for I had not only a patch kit, but a spare tube. Well, the spare tube had a damn hole in it so I opened up the patch kit. It hadn’t been used in well over a year (since before the big bike tour) and the glue had completely dried up. So I tried to flag down anybody passing by, and all these bikers with bulging seat bags just blew by, ignoring me completely, perhaps because of their fiendish concentration in fighting the wind that always blows around the bridge towers (where I had set up, for shelter from that wind). Finally a woman stopped, and admitted with embarrassment that she had all the tools I’d need, but hadn’t the foggiest idea what to do with them. I offered her a free lesson in exchange for a patch.

Well, I repaired the tube, no problem, and the Samaritan pedaled off into the sunset (almost literally), but then the damnedest thing happened. When I went to reassemble my bike, my chain had locked solid between the right crankarm and the chainring. Nothing I could do would free it. It was just stuck. At first I gingerly poked at it, not wanting to get my hands filthy (as my chain was in sorry shape—like Dad’s chain, with that ten-years accumulation of black oil and grit on it). Then I poked harder, pushed, pried, and eventually found myself ripping at the chain furiously, and somehow managed to severely lacerate my finger. Blood was absolutely spurting out of it—all over the ground, the chain, the crank, the pedals, everywhere.

Now I was truly furious, and started trying to roll the bike backwards to kind of roll the chain out. No dice—all I accomplished was to get blood and black grime on my handlebar tape and saddle. So I carefully tried to pedal the bike forward. Nothing. Blood shooting everywhere, hands a grotesque red-black color, my composure completely gone, I finally jammed my foot down on the pedal in a burst that I hoped would break the chain in two but at least end the stalemate. Well, the chain held fast, but my Shimano Dura-Ace FD-7403 (cutting edge!) front der somehow got snagged and was bent horrifically!

Now, this wasn’t just any derailleur. It was also kind of a trophy. You see, all the way back in 1989 I’d somehow broken [our brother] Bryan’s Dura-Ace front derailleur, and our boss at the shop assured me Shimano wouldn’t warranty it. I begged him to try (as lowlife mechanics like me weren’t really supposed to talk to the industry sales & service reps ourselves). He wasn’t interested, and in the meantime I had to buy Bryan a new der. But I always vowed I’d warranty the broken one and keep the replacement for myself. Finally I got around to it, years later when working at the Square Wheel, and thanks to my (nearly authentic) original sales receipt, I prevailed. (I had to fill out some form and describe the failure, and all I remember of my report was the conclusion, “I am incredulous.”) A beautiful spanking new 7403 front der was my prize. It’s the braze-on version, so compact they had to bend the logo around.

This was the most modern, sophisticated part of my entire bicycle, and now it was utterly ruined! And as if that weren’t bad enough, the bizarre mishap had also bent my derailleur braze-on all to hell! Now I was so enraged . . . words cannot describe it. I was like that guy in “Midnight Express,” rotting in the Turkish prison until he can’t take it anymore, who finally loses it and tears some dude’s throat out with his teeth. I grabbed that chain with my bare hands, and in a feat of strength matched only by Samson’s when he crashed down the coliseum around him, I broke that chain in two! So complete was my frenzy when I accomplished this that I continued the fluid motion, hurling that chain, discus-style, right over the railing of the bridge. I can only assume that in its trajectory downward it sliced off the arm of a fisherman in a small boat below. Needless to say this is by far the most irresponsible thing I have ever done.

Now before you condemn me for this brazenly stupid and highly illegal act, let me tell you I know exactly how illegal it is, from my job. We do risk management of offshore oil platforms and part of that is publishing all the safety regulations, which also delve into various oceanic legal realms like pollution, and on a slow day I’d read with fascination (okay, mild interest) how steep the penalties are depending on how close you are to land. Far enough out in the ocean, you can pretty much dump whatever you want, even an entire military helicopter, but if you’re caught dropping so much as a paper clip within sight of land, you’re practically pilloried. Well, what can I say? I’d completely lost my shit.

Did this awful act immediately come back to bite me? Did a Coast Guard cutter suddenly appear? Or did I face karmic payback, like my back suddenly going out? On the contrary, just as I set off toward home on my bike, flailing at the ground with one foot like a damn skateboarder to propel myself, two cyclists rolled up, assessed the situation, and offered to push me along. “You live in the city?” one asked. I said yeah. “What neighborhood?” I told him Russian Hill. “We’ll get you home. That’s on our way,” the guy declared. And they literally pushed me the whole way back!

When I got home, I violated all the rules of bike mechanics: 1) I worked when angry and frustrated; 2) I didn’t have enough light; and 3) I was so mad I couldn’t even remember the third rule, nor do I remember it now, so how could I have followed it? At stake was my pride and joy: the Ten Speed Drive Team Issue Guerciotti SLX. If I screwed up bad enough trying to straighten the derailleur hanger, the frame would be ruined.

On the plus side, Bonney was there to help me. Bonney is an old friend of mine: a giant, 12” croissant wrench, built in the USA to the stringent mechanical tolerances of a Lexus. Years before, at mile 95 of a century ride, I’d spotted Bonney lying on the road, and I was so tired I actually considered just leaving her there. I pondered the matter for a fraction of a second before turning back and swooping down to pick her up and carry her home, my trophy. She’s the pride and joy of my toolbox, which is impressive considering I have all kinds of Campagnolo tools, even the famous R-tool that straightens bent rear derailleur hangers. Alas, there is no purpose-built tool for straightening front derailleur braze-ons.

I had that dead Dura-Ace 7403 derailleur off in a jiffy, and then set about, hands still shaky with anger and drooling blood, to use Bonney the Wrench to straighten that braze-on. Almost sick to my stomach, I envisioned the braze-on snapping off, leaving a gaping hole in my frame. This horrific vision ended with a little window popping up in my brain—an instance of the saddest, most absolutely lugubrious computer error message ever, which I see from time to time when using my CompuServe Information Manager software: “Could not recover from failure.” Like the epiphany of a Generation X-er who dies of a drug overdose.

But instead, I came through. Anything I’d ever wanted to have and didn’t get was suddenly erased at that shining moment. Gone were the restrictions of original frame design; in a Zen moment I became the artist, hand-crafting that braze-on the way I myself would have wanted it in the first place, like the Platonic ideal of front der braze-on. You see, my frame—quite intelligently for a frame of its size, bless those wonderful Italian craftsmen—has a rather shallow seat tube angle, which makes for the perfect positioning for a tall person with a high femur-to-tibia ratio. Unfortunately, it makes for poor front shifting when the front derailleur braze-on is set parallel to the tube (which they all are, as far as I know). The front part of the derailleur cage is too far from the chainring teeth, you see. Well, I bent the braze-on to just the right orientation, a bit clockwise from where it had been originally, and though a bunch of paint flecked off, it was chromed underneath anyway.

I dug through my box of old bike crap looking for a replacement der, and found not one but two of them. How? Why? It’s like the old parts in that box copulate or something. Upon inspection I discovered both ders had something wrong with them, but between the two I cobbled together a working one. It was a grotesque low-end Campy number; I’d given up on that entire brand when the founder’s playboy son Valentino took over the business and created all the low-end lines like Victory and Triomphe. This cheap, ugly der was a disgrace to my beautiful bike, so to compensate I put on a spiffy new nickel-plated Dura-Ace chain that I was saving for my fiftieth wedding anniversary. When the repair was done and I’d cleaned most of the blood and grime from my hands, I went out for a test ride, and now my bike—she runs like a top. I don’t know if it’s the new derailleur braze-on angle or the Dura-Ace chain, but the Campy front der shifts great.

As for the mangled Dura-Ace 7403, it’s still beautiful, in its broken, tragic way. If you ever need spare parts from it, let me know. For now, it’s just another museum piece taking up space in our small apartment, without a jewel case or alarm system to protect it and show it off properly.

From the Archives - It IS About the Bike: Part 2

Introduction

Last week I ran the first half of a story I originally published in the Daily Peloton back in 2015. Well, to be more accurate I wrote it for some other magazine honoring the bicycle frame company Serotta, which was going out of business. As you shall see, my literary scruples prevented this from being a useful article to the Serotta people, which is why Daily Peloton got it. Since DP’s servers crashed a couple years back and all their content was lost, I’m serving the story up here.

Speaking of being lost, if you didn’t read the first half of this, go back here and do that now. Or not … you’ll figure out what’s going on eventually.

It Is About the Bike – Part II – January 2015

So, as I was saying last week, having wrecked my beautiful Mercian, I was getting by with an old Cinelli frameset on loan from my friend Nico. For months I’d been waiting in vain for news about getting my bent Mercian repaired. I waited and waited, and pestered and pestered Dave Whittingham, the manager of The Spoke, but to no avail. Eventually Nico wanted his Cinelli back and I still needed a bike. Thus, was time to buy a new frame but I had no money. (I’d spent it all on the Mercian and in fact still owed my dad at least $100 on it.) My brother Geoff, who had earned a fortune washing dishes at  the Flagstaff House restaurant, said he’d loan me the money for a frame if and only if I bought another Miyata. What was I to do?

I bit the bullet and bought a Pro Miyata, 57 cm, light blue with gold panels, for something like $300 (frame and fork). It looked pretty cool, but wasn’t as flashy as that Cinelli and rode just as bad. Of course I was happy to have a bike, but it was still a letdown.

At least it had proper lettering on the head tube, instead of the cheesy badge pictured above. And obviously it didn’t have any damn reflectors.

Nico worked at The Spoke, and I used to hang around with him there, chewing the fat. Not surprisingly, what we talked about was bikes. And what we talked about when we talked about bikes was The Perfect Bike. That it would be a Mercian was a given. The only question was, what color? Those frames came in like 60 different colors and if they didn’t have the color you wanted, you could send them a sample and they’d match it. We decided the ultimate Mercian would be the Colorado model (exclusive to the U.S., with Reynolds 531 tubing, racing geometry, an all-important lack of rack eyelets, and a 531 SL fork), with white pearl paint, red panels and a red head tube. But the red, we agreed, couldn’t be a candy-apple red because that was taken, being the iconic color of Colnagos like the Russian team had in the Coors Classic. So this would have to a slightly different shade: slightly on the plum or burgundy side, or a Moroccan leather red perhaps. We talked endlessly about this.

As time went on, it became increasingly obvious there would be no repair for my poor old Mercian, and eventually this became irrelevant: at fifteen, I’d outgrown my Pro Miyata and was therefore too big for the old Mercian anyway. Fortunately, at the same time I came into some money. An uncle had died three years before and left my brothers and me a grand each. My mom had wisely locked our money up in CDs earning a whopping 16%, and now, the term being up, she agreed to let me buy a new frame with some of my earnings.

So my mom drove me over to The Spoke, and I marched right up to the counter, where Dave Whittingham happened to be standing. I’d have liked to say something amazing and bold, like “I’m here to buy a new frame and I’ve got shit-stacks of money,” but of course I was too shy and polite. In fact, before I could even open my mouth, Dave said something apologetic like, “Look, I know what you’re going to ask, but I just have to tell you: Mercian can’t repair your frame. I’m sorry I got your hopes up.”

Before I could think of how to respond, he went on, “So because I feel bad, and because you’re good kid, I’m going to let you buy any frame I have in stock at wholesale.” As he said these words his glance drifted toward a row of frames hanging from the wall. Maybe he even gestured, ever so slightly, with his chin. And there, hanging right in front, was a pearl white Mercian Colorado with red panels and a red head tube, 60 cm ... just my size.

I couldn’t believe it. There it was, the frameset of my dreams. I asked Dave to take it down off the wall. The red of the panels is hard to describe. It was lustrous, deep, and unique. It was a beautiful frameset. I looked up at Dave. He had an amused expression, much like the one I’d have years later when, in the Red Light district of Amsterdam, I watched hayseeds from Oklahoma ogling the whores in the display windows.

But before making that frameset mine, I paused and reflected. I was in the catbird seat: a kid with many hundreds of dollars to spend, a sweetheart deal, and several bike brands to choose from. For the first time ever, I got to choose my frameset.

“Wait!” you might be thinking. “This Mercian, it was meant to be! You dreamed of this frame! It’s exactly what you’d already identified as the perfect bike! And clearly it had been made to order, just for you ... a leap of faith by this shop manager! Another brand?! That’s insane!”

And you’d have a point. But remember, I was a teenaged kid. All day every day my friends and I compared bike brands, watched bikes going by, drooled over bike magazines and catalogs, and debated the pros and cons of every make and model under the sun. Which was better, the Colnago Super or the Colnago Mexico? Were Olmos as good as Pogliaghis? Were Californian Masis as good as Italian Masis? Was it sacrilege for a high-end Italian Bianchi to be painted anything but Celeste #227, that milky washed-out green color? And was it even worse for a lower-end Japanese Bianchi—a totally new phenomenon in those days—to be painted Celeste #227? Who made better tubing—Reynolds or Columbus? And where did Bob Jacksons fit in this bicycle pantheon?

And keep in mind, this wasn’t just any purchase. What do teenagers blow their money on these days? Mostly hi-tech stuff, right? Playstations and smartphones? Those are guaranteed to be obsolete in a couple of years anyway. Not so with a bike, now that I was basically full-grown. I might have this bike for years and years, for thousands and thousands of miles. It could be the bike of my life. This wasn’t like buying a consumer good; it was more like buying a horse.

My friends and I loved our bikes like they were family. After a great ride, you’d lean your bike against the wall, gaze at it, and actually sigh with pleasure. I’d even go give it a little pat on the saddle. My bike meant more to me then than a modern teenager could possibly understand. A bike was freedom. My parents never worried about me, so I could ride as far as I want. My pals and I did 80 miles at a shot, day after day (having nothing better to do). Our suntans were asymmetrical from slowly climbing north to Estes Park and quickly descending back south. A friend and I capped off the summer by doing a 130-mile trek over the highest pass in North America. Only a bike could make such an adventure possible. Our bikes were our lifestyle, our identity, our everything.

So: what bike to get? The Spoke carried Olmos, but my brother Max was buying one on layaway and I couldn’t appear to be copying him. I’d never cared for Motobecanes (which all my brothers had had) and the Prolight, Motobecane’s flagship, was rumored to be flex-y. The Specialized Allez was high-end, but it wasn’t Euro. Ah, but The Spoke had Serottas. They sold lots of Serottas.

Timidly, I asked to look at one. Timid? Well, yeah. Obviously it was the Mercian that ought to be my destiny, after all. But Dave had said “any frame.” He graciously took me over to a bright metallic violet Serotta Nova in my size, built up with Campy Super Record. (Back in those days, when all good bikes were road bikes, and when the sales floor didn’t have to accommodate today’s menagerie of mountain bikes, commuting bikes, cyclocross bikes, lifestyle bikes, beach cruisers, and fixies, you wouldn’t believe the deep inventory of kickass road bikes shops could carry, especially in Boulder.)

The deck was stacked against the Serotta, of course, but I had to admit it looked great. Nico, who’d either gone to the shop with me or was there working that day, had to agree. So I took it out.

I hammered away on that bike, taking the corners hard, following the course of The Hill Criterium, one of the big Boulder races. I really put the Serotta through its paces, shoving on the pedals with everything I had. And with a strange mixture of delight and consternation, I realized this bike rode amazingly well ... in fact, possibly better than my Mercian had. It just felt so lively, so quick. I was astonished, and was overcome with the turmoil of deciding what to do.

Maybe, I reasoned, I was just comparing this to the Pro Miyata it was replacing. That Miyata was oddly back-heavy, like the rear triangle had solid tubes or something. From day one I hadn’t much liked it. So I rode back to the shop, borrowed Nico’s Mercian, gave it a good hard test ride, then switched back to the Serotta, then back to the Mercian, etc. I didn’t dare say this out loud, but if anything the Serotta rode better. Could it be the pins the Mercian was built with, that my brothers had taunted me about? No, that’s a dumb gag I just made up. That idea never crossed my mind at the time, and I didn’t kid myself that the difference was a matter of workmanship. Probably the Serotta’s Columbus SL tubeset was lighter than the Mercian’s Reynolds 531. Or maybe the Serotta’s geometry was more aggressive. Maybe it was something else about the bike (lighter wheels?), or maybe I just had a deep-seated, perverse impulse to make trouble for myself.

Quietly, I placed the Serotta back in its stand on the sales floor, next to several other Serottas much like it. And there was the Mercian, up on the counter, standing proud, propped on its bottom bracket and fork tips. And suddenly I had this strange feeling: my tension subsided as it dawned on me what a good problem this was to have. I had money, and I was about to have a new frameset, and whichever I picked, it was going to ride like a dream.

My mom was patiently waiting. I had to make up my mind. I hadn’t ordered that Mercian myself, but it had obviously been ordered according to my specifications. To reiterate, its existence was an act of faith. Teenagers are known for their pure id, but now my nascent superego actually asserted itself: I bought the Mercian. Maybe that was the first truly grown-up thing I ever did.

So did I always regret not buying the Serotta? Did I managed to love the new bike? Of course I loved it. In fact, it ended up becoming, of all the steel frames I ever owned, my second favorite. (And what was my very favorite? Well, that’s another story.)
