An Evolution in Fit

I’ve been fit by more alleged “masters” of the bicycle fitting process than I care to remember. What I’m even less interested in recalling are the specifics of some of those fits. I’d prefer not to have had the journey, but along the way, I’ve seen—and learned—a lot.

One Italian frame builder took three measurements of me while I was in a cotton shirt and chinos as I stood in his booth at a trade show. Net result: The bike was gorgeous, handled like water flowing through a pipe and was at least one centimeter too big, and that left me too stretched out. The measurements of my “custom” frame also coincided with his stock 60cm size. I’d committed to buying that frame set; the day I admitted to myself that I needed to sell it, that it would never really fit me, was a sad one.

Another fit master, one who is known as an LA fit guru wanted to put me on the smallest frame anyone had ever suggested for me, a 53. That was perhaps the biggest (smallest?) bullet I ever dodged. I tried riding the bike around his parking lot. All the while he was beaming, commenting on how flat my back was. He had the largest supply of 14cm stems I’d ever seen. Little wonder.

I’ve had other fits that looked more or less right to most folks. One recent one resulted in a saddle height that was more than a centimeter too high; it looks ridiculous to me to write that, so I respect it must look even more ridiculous to read that. I got into that pickle because of a decision I’d made years before, that I would fully commit to whatever fit I was placed in and not begin monkeying with it a week later.

It would be easy to look in from the outside and pronounce these machinations silly, for someone to conclude that they’d never get caught in such a trap. There were times when I’d look at a change and think, “Okay, that last fit was definitely off; this one is what I need.” But the fits I had were never so far off as to be glaring errors—a fish in a Coke bottle.

What was interesting to me was that over the years. almost all the fits I gave myself over to were never far from that first fit my boss at The Peddler Bike Shop gave me with the Fit Kit in 1989. Later, I attended the New England Cycling Academy, where I was certified in the Fit Kit. In 1992, that was the most thorough course going in fit. Later, I went through Serotta’s early program, and even had the first generation of the Serotta Fit Cycle in my garage for the better part of a year. I’ve been around a number of different fit methodologies for a long time. There have been times when I was bombarded with so many different fit ideologies that it felt like rush week at a big university.

Despite the variances in my own fit and the conclusion I drew, which was that none of the fits I’d received over the previous 10 years were quite right, I do think the state of bicycle fit is vastly better than it once was. The worst fits I see on the road (and on mountain bikes) are invariably riders on bikes that were sold more than 10 years ago, often closer to 20 years ago.

I’m preparing to write about at least two custom bikes in the next year. As a result, I decided I wanted to get my fit reviewed and for that I decided to go to Steven Carre of Bike Effect in Santa Monica. There are a bunch of very talented fitters in the LA metropolis, so making the choice wasn’t easy. I selected Steve in part because I respect the fits I’ve seen coming out of there and in part because of the number of custom bikes they are selling.

Steven’s approach intrigued me in part because he’s spent time learning most of the major approaches to fit. He is certified by the Serotta International Cycling Institute, Retül and Specialized’s SBCU. Of course, you can have all the fancy gadgetry that drug money can buy, but still not know what you’re seeing. That’s what made my experience with Steven different.

I’m not as fast as I was in 2003, but my flexibility hasn’t changed significantly in that time, which is what makes his results so significant. In many regards, I’m the same cyclist, but not all. I’ve lost height because my spine has shrunk. Those details are easy enough to diagnose. It’s the other details he caught that everyone else had missed: a slight leg-length discrepancy, but one that is not skeletal in nature; a pelvis twist that causes me to sit on the saddle not quite perfectly straight; and unusual back flexibility that allows me to ride fairly low even though my hamstrings aren’t all that flexible.

Steven diagnosed the changes to my fit he thought would be most helpful in short order, but he took me through a couple of extra steps in an effort to be super-thorough. He set up the latest generation of the Serotta size cycle with my current fit. This latest version of the size cycle, if you haven’t seen it, looks some ultra-advanced spin bike, like BMW had entered the exercise-equipment market.

Honestly, when I first saw it, it looked over-thought, the proverbial better mousetrap. And then Steven did something simple, something amazing, something simply amazing. He took an electric driver and began moving the handlebar away from me. With the original Serotta size cycle, you could set it up in nearly any fit you could imagine, but to do so, the rider had to dismount the bike and then remount it. With the new version, you’re able to make adjustments as the rider is pedaling and the electric driver gives the fitter the ability to make smooth, gradual changes.

With that electric driver Steven was able to move the bar forward and backward, from Obree Superman to kid’s bike. He did the same thing with bar height, taking the bar from English 3-speed to pursuit bike. We took a couple of passes in each direction and I’d tell him how I felt periodically, doing my best to indicate when the bar’s reach and height felt most comfortable. In an effort not to influence the process with any opinions of my own I looked forward as he made changes.

Steven told me that with each pass I was consistent in where I indicated the bar was most comfortable. Not only that, Steven noted how my upper body was less tense in the new position than it had been in the old position. More relaxed means more miles without discomfort while riding in the drops.

Before I went into the fit my fear was that he would move the bar up. Part of my concern was that I would need to add spacers on forks that had already been cut to length, and on top of that was the challenge of making sure my fit didn’t conflict with manufacturers’ guidelines for the maximum length of spacers between the headset and the stem. As it turns out, Steven moved the bar back 1cm and down 2cm. That was a surprise.

Because my saddle came down a centimeter as well, on a great many production bikes I’ll be moving from something in the 58cm top tube range to options in the 56.5 to 57cm range. That will prevent me from having to run 10cm stems, which make the bike a bit more twitchy than I’d like.

We made the changes in stages, moving the stem by a centimeter every two weeks and the saddle by a half centimeter. I’ve been riding with this new fit on two road bikes (I changed my mountain bike fit as well) for four months now. I can say that I’ve got more power in the saddle now and have enjoyed greater comfort in my shoulders on long rides.

I’ve had several different offers to be fit with various systems lately. While I’m curious to know more about the processes, I’m reluctant to let anyone else work on my fit. Reluctant the way I’d feel were I to face a firing squad. I played along for a long time, but as I age my body has become fussy. I may not be the old cat laying in the sun just yet, but experimenting with my fit has the potential to reduce how fun riding is, and in that I just don’t see the point.

FSA K-Wing Handlebar

K-wingI’ll get the unpleasant bit out of the way. FSA claims this bar weighs 215g. Mine weighed closer to, well exactly, 242g.

But I don’t care.

I’ll admit the first time I saw the K-Wing it looked as ridiculous as Kiss’ stage outfits do today. I mean, a riser bar for the road? What gives?

Then one day its beauty clicked. I realized the K-Wing is a deep-drop bar that isn’t. The mistake I commonly see in setting up the K-Wing is by positioning it so the bar top is at the same height as the previous bar. Wrong!

What makes the K-Wing so great is the ability to position the drops at the same height as other bars (thus making the levers the same height) which ultimately places the bar top a full centimeter higher than it would be otherwise. The result: You sit up higher while climbing while needing fewer spacers below the stem. Your bike looks more PRO in profile.

I’m not one to get too hung up on the look of a bike; I’ll flip a stem upside down if it’ll give me the fit I seek, but there is much to be said for a bike that looks elegant.

I will admit I’ve struggled to reconcile the fact that the switch from aluminum to carbon fiber as the raw material caused prices to quadruple while cutting lifespan to strictly single-serve. Crash it: Replace it. So yes, I struggle with more expensive and greater fragility. But then I get back on a bike with an aluminum bar and even with cork tape I wonder who turned off the comfort. I don’t have carpal tunnel, but I don’t want to get it either. The vibration damping that comes with carbon fiber increases comfort so noticeably it’s a wonder we didn’t make the switch sooner.

The first time I rode a carbon fiber bar I felt like a soon-to-be addict trying crack for the first time: “Where have you been all my life?”

The internal cable routing is—I won’t lie—a pain in the kiester to deal with and the tight bends can reduce braking and shifting performance if you’re not careful. I keep a special cable around to aid with the routing when I replace housings. But the liability posed by price ($229) and limited lifespan are more than overcome in my opinion by the deep drop that doesn’t require increased flexibility.

I hope this bar is never discontinued.
