Ospw campagnolo blk coated

Developed and designed entirely by CeramicSpeed, the Campagnolo oversized pulley wheel system is advanced for optimizing bike performance. Everything from the bearings to the cage is made from the highest quality materials. The oversized aluminum pulleys are equipped with standard or coated ceramic speed bearings, which reduce friction to a minimum. The 13-tooth / 19-tooth OSPW for Campagnolo provides 40% less friction over a standard 11-tooth Campagnolo pulley wheel and fits a 32-tooth cassette. The OSPW for Campagnolo is compatible with all Campagnolo electronic derailleurs (EPS) and all rear derailleurs with mounting sleeve, regardless of age and model. At this point, this OSPW system is not compatible with Campagnolo 12-speed Record and Super Record gears.
