Whether shredding the local trails with friends, winning the district criterium, attempting your 3rd Ironman (TM), or a casual commuter, we want you to be happy with how you feel and perform on your bike. We're satisfied when every rider achieves their desired riding experience. With this in mind, we’re proud to be a Body Geometry Fit studio, the best way to make sure your bicycle fits your body.  


The Fit Process

Body Geometry Fit is ergonomically designed and scientifically tested to maximize power, endurance and comfort through a systematic customization of your bike and equipment at all three contact points. 

Your Body Geometry Fit includes:

Pre-fit Interview

Bike fitting is very personal, and isn't "one size fits all." As such, we'll interview with you to understand any past injuries, talk about current discomfort and discuss your goals for the fit.

Physical Assessment

We'll evaluate and document your total body flexibility and asymmetry, particularly relating to your feet, knees, hips and pelvis, spine, neck, shoulders, elbows and wrists to gain the most accurate information about you.
