I have OP Ceramic rims on 3 of my 4 bikes. Definitely find this an excellent product, especially in the wet. In dry,they are a bit touchy, but nothing you cannot get used to. I have Campy Record brakes on all these bikes, and use the standard Campy brake pads. They may wear quickly early on, but my experiance is that they will then be quite stable for some years. Not to dis' the use of those specialized green ceramic specific brake pads, but just to note that some standard pads work well, too.
