Been riding / training for over a year, with very significant gains in speed and performance over the past year. I usually have ride spilts in the top 20-30% overall in my races. It's pretty hilly and windy where I am yet I usually average well over 20 mph in my races. I have gone through exhaustive bike fits and now evangalize the benefits. One thing I do notice though...my left foot and knee are perfectly alligned and linear. My right however, the heel angles inward and the knee pushes outward a bit. I notice this much more when I am tired or struggling through a difficult portion. Could this be an indication of leg length difference or flaw in body mechanics?
