This rider has an extraordinarily long femur (thigh). Note the close proximity of the elbow to the knee. Even though the extension of the upper body is perfect and the rest of the position is very, very good the long femur complicated fitting, necessitating modifications to the crank and pedal cleats. This was a tricky fit that came out very well. No margin for error here, it was either perfect or it didn't work. The customer drove from Pennsylvania and I worked approximately 4 hours on this position after building the bike to her measurements.
