I have the Shimano Dura-Ace SPD-SL 7750 pedals & cleats. It must be time for new cleats, as I've been using the originals for a total of 3 seasons (2 racing). I notice some noise/play when I pull up on the pedals. However, I recall also hearing this sound much earlier on, too - probably at the end of my 2nd season w/them. Is this normal? I wouldn't think so, as the pedal stroke/circle doesn't seem 100% efficient. I know my CrankBros Candy SL's, that are on my cx bike, don't have this issue.
