aw man i switch back and forth all the time and last night something horrible happened.
my right crank was in the 11o'clock position and usualy when im on my fixie i push off the ground with my left foot while i put a little pressure on the right pedal while it gets carried around to the front. but this time i was on my geared bike and when i put that pressure on right pedal it just spun the other way and i cracked my nuts on the toptube. it was horrible painful and public. i hope i dont make that mistake again.
