The debate about greasing pedal threads, my bike shop buddy went off on me.
So I was in my local shop, Bikes Direct in Portland, and I'm chatting with the head mechanic Dave about installing new pedals on my commuter. He says I gotta grease the threads on the crank arm, no exceptions, or they'll seize up in six months. But then another guy, a customer waiting for a tune-up, jumps in and says grease is a bad idea because it reduces friction and the pedals can back out on their own. Dave nearly flipped his lid, saying that's only if you use too much or the wrong compound. Who's right here, has anyone else seen a pedal actually back out from a little grease?
