i'm really short, like 5'2", but have always run 170mm cranks because that's just what came on my bike. but i'm starting to think I'd be better suited to 165s. i'm going to try borrow a crank for the fall and seeing if i like it.
related - if i make the jump i'll need a new pwoermeter. don't really have funds for a quarq. does anyone have experience with the pioneer single leg meter?
