PERFORMANCE AND COMFORT = BIKE FIT
"Competitive cyclists in search of marginal gains should be comprehensively screened for anatomical and biomechanical abnormalities before Bike fit or positional set-up. Efficient, injury-free cycling is reliant on pedaling symmetry, which is reliant on efficient lower-limb biomechanics, correct foot function, and a stable, level pelvis. The structure and function of the foot dictate how effectively pedal forces are transmitted via the foot/pedal Interface down to the cranks, and potentially how deleterious forces are transmitted up the kinetic chain, creating pelvic disruption. Leg length inequality must be clearly differentiated into anatomical and functional and then addressed appropriately to achieve a successful outcome. Biomechanical problems can be addressed successfully only if they are recognized and diagnosed. Ideally, the screening process should involve a sports medicine therapist with specialist knowledge of cycling biomechanics and foot function. In competition, marginal gains can represent the difference between success and failure." Nick Dinsdale
