Finding a Fitter


As time goes on, we’ve seen a dramatic increase in the number of shops offering bike fitting services. There are also more and more methods, high tech tools and certifications available. Bike fitting has certainly become more main stream over the last few years and with all the options and marketing out there, choosing a fit specialist can be confusing.

Let’s start with the tools. It’s common now to see motion capture systems used in fitting along with laser measuring devices. We’re seeing a few pneumatic assisted fit bikes too. Power analysis has also become another common and very useful tool for modern fitters. Although these tools all make for a great show, they are only as accurate as the person using them. A good analogy is that anyone can go and buy a tig welder but can they build a frame that is safe to ride? A tool is merely a tool no matter how cool it looks. We use motion capture from Retul at Bespoke. Without understanding anatomy and human movement, it is useless. The information gained through performing thousands of fittings throughout the years is far more valuable than any tool today or any produced in the future. A tool cannot listen and observe; only an experienced fitter can.

Fit methods are important to discuss as well. These days there are quite a few; Wobblenaught, F.I.S.T., Retul, Serotta/SICI, Specialized Body Geometry, and more. Most shops employ one method. This is because that makes it easier and less expensive to train a fitter. It also allows a regimented “fit by numbers” approach which takes less time. We certainly subscribe to some methodologies more than others but we don’t limit ourselves. By understanding all of these methods, we can apply all of that knowledge more appropriately based on the Individual we’re working with. Whether you’re a time trial specialist, road racer, century rider, mountain biker or anything in between, we can apply what we know and accurately fit anyone.

Experience really is the key when it comes down to it. Years of fitting all the different body types, all the different disciplines in cycling and addressing all the different symptoms are crucial in truly providing the best fittings possible. Understanding bike design is also important. Understanding how someone is moving on a bike requires an eye developed over years. Seeing physical asymmetry when someone is pedaling is not something you pick up in a one or two day class. The causes of symptoms of discomfort on a bike are not always easily detected and the methods by which they are addressed can be many. It takes experience.There is tremendous value in working with the same person over time as well. They can see how you adapt to changes, watch improvement and more easily address your future concerns.

Talk to your potential fit specialist. Ask them about their experience and qualifications. Talk to them about your specific concerns and ask them how they would address them. Ultimately it’s about you, your goals and your bike, not a mathematical equation and a laser.
