Ya I tried that... If I raise the saddle anymore it would straighten my leg.
heel of your foot on the pedal. leg straight is about the right height,
so when the ball of the foot is on the pedal the knee bend is adequate.
Do you have an example of bikes without much seatpost?
look up pictures of pre WW2 & late 40's race bikes .. fit theory changes with time..
that all legs?
can you stand bare foot over that top tube .
