Why do you like such short cranks? Do you spin really fast?
Thanks!

I don't know, what's really fast? Judging by other cyclists I see, I often see cyclists who spin as fast as I, but only occasionally do I see someone who spins much faster; so I guess I'm at the higher end of the "normal" range. These cranks are 140's, which is frankly a little on the small side. I've tried everything between 127 (5") to 175 and found that crank length really doesn't make much difference at a normal cadence (90-100 rpm). The short ones offer a small advantage at a high cadence and a small disadvantage at a low cadence. In deep snow, they are a disadvantage (confirmed this morning) but I don't ride in that very often.
