3 of the bikes in my "fleet" have OP with Ceramic. I have these on my Spectrum Ti touring bike and have been through plenty of rain, including descents in the Alps. Braking performance in the dry is like the first time you drove a car with power brakes --but you quickly get used to it. Performance in the rain is excellent --at least relative to a normal rim. My touring bike has Campy Record brakes and their standard brake pads. I wore out a set of these within a few hundred miles when the bike was built. But since, I have used the same pads for several years. The ceramic does not wear off, but is smoothed out. It is still effective. I have also used those green ceramic-specific pads on my other bikes, and they are fine as well.
