I like riding with crank bro's pedals and love the simplicity of the design but, I've had numerous issues with them, including a candy 3 completely seizing. An LBS mechanic recently told me they won't carry crank bro's pedals because they have quality control issues. I'm considering converting to speedplay frogs; a bit more expensive than candys, and i don't think they're double sided. Anyone else commuting on them and if so what do you think of them?
