use shorter cranks (165). Pedal strike can be an issue though its nothing I've personally experienced. The most annoying part is when im close to a curb and i smack the pedal as its comming down. Thats usualyl a lowspeed, trying to sneak around a car thing. i sometimes do a little skip if i think im going to fast, or skid through a corner if im feeling a little reckless and its a route im familiar with (and know where all the potholes are)
