Are small bikes made too stiff and big bikes too floppy ?
I will have to go looking for it, and maybe this will jog someone's memory, since I think I found the link on this forum originally, but there is a research paper that compared power, torque, and RPMs for something like 30 riders, and the numbers aren't as straightforward as one might think. The basic takeaway was: find the crank length and RPM that is most comfortable for you.
