you must have missed my first response in the thread...my pedals are campy chorus, but with the same 'squeak' that developed soon after breaking them in from new.
Right after I sent the last post, I saw your original explaination. Thanks to your help and the suggestions of several others, I've solved the problem. I didn't think about using some kind of liner under the cleat until you described how campy sets up theirs. I took gasket paper and traced the outline of the cleat, cut it out, and then used a razor blade to cut out the rectangular holes for the screws (Gasket paper works well because it holds together when it gets wet; you can buy it at any auto parts place). I used lithium grease on the front and rear contact points and, walah (sp?).....no squeak on my 50 mile ride into work. I tried the furniture polish, but it wears off on the long rides. I tried silicon spray, but it has the same problem. It just doesn't stay on as long as the grease. When I took the cleats off, I could see spots on the outside back corners of the cleat where they had been rubbing on the bottom of my shoes (the cleat left some small divots in the bottom where it had been rubbing when it flexed). It was so nice to be squeak free. Maybe there's a marketing opportunity here?
Many thanks.
