3 Overlooked Signs You Need a Bike Fit

Has it been a few years?

In a previous blog we talked about some common problems we see with bike fit, and discomfort and injury are obvious signs you should address bike fit issues. Many times, however, cyclists who would benefit from a bike fit appointment are not experiencing pain. The body has an amazing ability to compensate for less-than-optimal movement patterns, but riding with a poor-but-functional fit often means you’re working too hard to produce too few watts. Here are three commonly overlooked signs you should get your bike fit checked.

You See Uneven Wear and Tear

Your bike is symmetrical.  It is designed with bars of equal curve, crank length, and stance.  Everything about it is equal right to left. The body is asymmetrical.  There are differences in strength, flexibility, structure and function, both front to back and right to left.  I have had to explain this to my fit clients many times and they seem hesitant to accept that they aren’t perfectly balanced.  You never were perfectly balanced, and if you think about it, you’ve probably bounced off the ground a few times in your life, too. Those impacts and compensations changed your symmetry. The goal of bike fitting isn’t to force your body into symmetry, but rather adjust the bike to compensate for your unique asymmetry.

Signs of asymmetry we can look for include: uneven wear on the saddle, hoods, bar tape, cleats, insoles, and/or crank. Basically, anything you touch or any contact point with the bike can bear the signs of asymmetry.  If the wear on these areas vary from right to left, it could be a sign that you are asymmetrical and that we need to account for that.

You might need different amounts of arch or forefoot support on each foot.  Heels hitting your cranks may require us to adjust your cleats or add some spacers. If your feet are rotated out, we aren’t going to set up your cleats straight to force you into alignment, but rather set them up to match the natural rotation of your feet, which will feel straight and centered for you! Uneven saddle wear is typically a sign you have a strength or flexibility imbalance that is causing you to pedal slightly askew, rather than an indicator of an anatomically asymmetrical pelvis. However, saddle wear most commonly indicates that a rider is on the wrong width or shape saddle. The wrong saddle won’t support both sit bones and can often cause a rider to pick their favorite side, leaving the other unsupported and hanging off in space.

It’s been a few years

Maybe your gear isn’t necessarily falling apart, but it’s been 5 years since you last had a bike fit and you have changed.  Or like I said earlier, maybe you’ve bounced off the ground a few times! The body changes. Your flexibly and strength changes, at times getting stronger or more flexible, and other times less.  Your job and lifestyle changes. I coach an athlete who retired and started losing weight unexpectedly, and a few weeks later we realized it was because instead of sitting at a desk all day, he was walking the dogs, doing yard work, and organizing the house.

You may race mainly crits one year, and fondos the next. Comfort for all day riding will likely warrant a more relaxed position than one designed for a high-intensity hour of power. Changes in your activity level, lifestyle, job, or goals can be very good reasons to take a second look at your bike position.

When you are new to cycling, you may might want to update your fit every year over the first 2-3 years.  I’ve observed that newer riders have less range of motion in their fit, and they also have less proprioception to the mechanics of bike riding.  Their initial fit should put them into a position that accounts for their current flexibility. As they increase their mileage their flexibility and strength will change and so will their fit.  As they rack up miles they also become more aware of their body and its mechanics, which often warrants updating a fit.

On the other side of the spectrum, riders who have been at it for a long time might not be aware of the very slow changes that are happening in their body.  Just as you don’t see your hair grow day to day, you may not notice how age, lifestyle, body weight, and seemingly insignificant changes all accumulate into needing an updated fit.

You Have a DIY Bike Fit

More information is available at our fingertips, and in our pockets, than ever before in human history. You can Google and Youtube all kinds of information about training, nutrition, recovery, and even bike fit. There are advanced tools you can use to create your own DIY bike fit. The basics of bike fit are not that difficult to figure out, and people can generally create a reasonable approximation of a good fit. But is that good enough?

A professional bike fit is one of the best investments of your time and money. You already spend hundreds of hours each year training to increase your power output and optimize your performance. In some cases, I’ve had athletes train for six months to achieve a 20-watt increase in sustainable climbing power. I’ve also had athletes gain 20 watts of sustainable power through changes to bike fit – with no changes to their fitness level.

With a DIY bike fit, you just don’t know how much potential performance you’re missing out on. Your fit could be great, and if it is I’m not going to change anything just for the sake of justifying your visit (no fitter should). Confirming a position is optimal removes doubt and helps improve an athlete’s confidence. But if you’re leaving watts on the table and we can increase your power output or improve your comfort by tweaking your position, you will be able to take full advantage of all those training hours.
