Specialized Bikes, Canton, MI, Fitting Machine Picture - Fraser Bicycle


Bike Fit is a marriage of bicycle and rider. While the human body does an incredible job of adapting, it is our job as fitters to adjust the bicycle to the rider and not the rider to the bicycle. A rider should not be stretched or contorted to achieve the "ideal" or "Pro" position. Rather, the bicycle should be an extension of the rider and reflect his or her riding style.

Dynamic bike fit is better than static bike fit. Fit while pedaling under load must be considered when fine tuning saddle height and cleat positioning. Static formulas for deciding height do not take into account a riders natural ankleing pattern under load. As said before, "we must make the bike fit the rider", and not attempt to place the rider in a prescribed "ideal" or "Pro" position.

Cycling is a sport of repetition. A cadence of 90 revolutions per minute is roughly 5000 revolutions per hour. A six hour century would require 30,000 pedal revolutions. Obviously the positioning on the bike must be as perfect as possible to prevent repetitive use injuries, and this is why a precision fit is a must for even casual cyclists.

Josh Rickaby - VP Infinite Multisport

When I first went to Fraser Bicycle to have a fit, I thought I had a good position and just needed a few tweaks. Taylor showed me how to dramatically improve my position from an efficiency, power and aero perspective. Over the last three years I have worked with Taylor on multiple areas of my bike position, from seat style, crank length, drop, cleat position and head placement. The end result has been I am more powerful, aggressive and aero without sacrificing comfort. I cannot recommend highly enough the value of a professional fit and they don't come any better than Taylor and Fraser Bicycle. Taylor is a triathlete and understands what we are all trying to achieve. If you want to take your bike to the next level the Fraser fit studio is the place to do it.
