When i'm exerting a whole lot of force on my pedals (climbing) I feel on the upstroke (both sides) a click and some movement upwards in the cleat. I'm not sure if it always happens, could just be that i'm not pulling hard enough sometimes but i will keep checking.
The pedals are new Look Keo Carbon (from probikekit, but i hope they're still kosher) and my shoes are entrance level Sidi's from a year or two ago (they're the rare model with straps that go inward - the dumbest idea ever and the only such model i've seen - cutting them down was the only solution i could come up with since they hit the crank as the leather stretched and they got too long).
Anyway, I'm wondering whether anyone else has come along this phenomenon with the LOOK Keo's, otherwise I'm going to assume it's the connection between the cleats and the shoe plate that's giving. I haven't been able to make the cleats move from the shoe off the bike because it's hard to get enough force on them.
Any help would be much appreciated, thanks.
