Was hoping for some insight. When I pedal for a while, and then stand on my pedals as if to go downhill, I get a clunk from my cranks. It is definitely not the pedals as I just replaced them and the problem still exists. It seems weird to me because the crank arm interface should not allow any play.
I've checked to make sure everything is tight -- done everything short of completely ripping it out and re-installing, which I'll probably do this weekend. Just wondering if anybody happens to be familiar with what's going on.
