Conversion bike, 175 cranks, tiagra (with external bottom bracket= slightly bigger Q factor i think).
pedal strike only twice, once going down a "dropped" curb (its dropped 5" from the curb, so its really sharp) i was turning and it caught, skipped a couple feet, and kept going like i meant to do it.
second time, was moving through gridlock, i got too close to the curb and it smacked down and tossed me up a little bit (it was weird, i had hopped up a bit just so that i could get my bag over a wing mirror, and it struck tossing me up a bit...) but i kept going no problem...
i think I can (as of yet) stay on when stuff like that happens only because of all of my less then skillful mountain bike riding. So I'm use to hitting a pedal from trying to get that extra stroke in before the corner.... my lack of skill on the trails, has increased my skill off the trails... hahaha
