The Process

Bike fit is a process, not an event. Your body adapts to more training and regresses from less. We aim to understand the athlete's goals, background, physiology, and morphology, and are fitting the bike to that athlete. If necessary we start a dialogue using your cycling coach or other practitioners to find the long-term solution to your healthy cycling.

I began doing bike fittings over 14 years ago but my passion and skill as a fitter has evolved rapidly over the last 5 years. After years of pursuing graduate-level education in exercise physiology and biomechanics to become a coach and help athletes, I finally saw my own potential; being able to combine an engineering background and a coach's training to truly understand the interaction of the body and bike to provide ongoing solutions.
