Have had Mavic ceramic rims on my Spectrum Ti touring bike for 10 years. Can attest to their excellent performance in dry and especially when wet. Major improvement wet vs regular rims. They work well with those (usually) green ceramic specific brake shoes, but at the time of this build there we none of these on the market, so I used the standard Campy Record brake shoes. The first set got chewed up in a few months, but since then, I have used the same shoes for many years. So be prepared for this when you do an install.
