Has anyone had any problems with the Shimano SPD-SL pedals?
I bought a pair of the cheapest (the 105 version) and I had this problem that the cleat would slip on the pedal .This only happened under heavy load, like going uphill, but it was really annoying given that there was an associated sound of the cleat grinding over the pedal. My cleats were very well tightened ,so it wasn't the cleat slipping on the shoe.
I've head so many good things about these pedals ,I was upset to have to return them.
