Campagnolo 11-speed rear derailleurs work better with ceramic speed pulleys, which are a marked improvement over stock. They reduce frictional drag and increase bearing life. Less drag means more power transmitted to the rear wheel.
These are standard aluminum pulleys with stock Ceramic Speed balls installed in our hardened-steel races. These test better than anything else on the market.
These are compatible with all 11-speed Campagnolo derailleurs, mechanical and electronic.
