My Bicycle Fitting Methodology
I start by establishing a relationship with the Rider learning his/her short and long -term ambitions.
My fit method is simple and effective. Whether we are looking to solve discomfort or add power, I identify the root source. The harmony between the Rider and their bike is the primary focus.
There is a science and a natural feel to fitting. Individually the adjustments may seem small but collectively they make a meaningful difference. What I love about fitting is that the results can be felt right away. Its instantaneous. It is very rewarding to me to see my Customers do more (watts) with less (effort).
I have an intuitive understanding of human dynamics and how the body relates to a bicycle.
-
foot and cleat relationship
-
sitting bones contact points
-
dynamic arm and leg movement
-
pelvic tilt
-
line of sight
The Rider should feel as if they are IN the bike, not ON the bike. This sensation provides quicker inputs/outputs leading to more efficiency which improves Rider performance. Fitting happens in small steps, but it is no small thing.
I am a competitive cyclist - experienced in multiple cycling disciplines. Road, Mountain, Cross, Downhill, and Gravel. I have a unique insight and cross-functional fit knowledge of multiple riding positions.
