I did the KOPS measurement with my current setup. My knees are a bit 1cm behind the pedal spindels. I ride a 54cm frame with 54cm top tube lenght. 120mm stem. I am 5`9". I think I have an unsual longer thigh lenght. I am on a Fzik Aeron saddle and Ritchey WSC seatpost. The seatpost clamp isn't at the center of the saddle. A bit forward. I am comfortable with the setup. I can sustain high tempo effort for 2 hours and 30 minutes on the bike. I can spend 85% of the time racing in the drops. When I pedal I felt that I am pushing the crank foward more than down.
