I am 6 feet tall and I am riding a 57 cm bike with 170mm cranks. I have played around with the kops method of seat placement and my knee is forward of the pedal axle. I have a nitto high extention quill stem for the bike but I think that it would feel a little better if I could raise the bars just a little higher.
So the though came to me that longer cranks would require me to lower my seat and would put the pedal axle under my knee. By lowering the seat, the relative position of the bars will be higher.
Has anyone tried using longer cranks to aid in fit or is this just ridiculous?
