Compagnolo 12-Speed Road Ceramitech OS Pulley Set (12T upper/14T lower, set of 2)

Rock solid chain control means crisper shifts while Ceramitech bearings channel all your hard work to the ground.

Our BBInfinite Campagnolo 12-speed compatible ceramic pulley set features a DELRIN® 510GR construction, a fiber reinforced polymer specially suited to high strength situations where resistance to deflection is paramount, such as every time you shift. The Ceramitech bearings are in-molded for absolute security and durability as well as ease of maintenance.

Our BBInfinite Campagnolo 12-speed compatible ceramic pulleys blow the stock pulleys away when it comes to spin, and the oversize diameter reduces chain pin working angles to eliminate every bit of friction possible.

These pulleys are specifically designed to FIT Campagnolo 12-speed and 13-speed road and gravel drive trains.

It's a mystery to us why major manufacturers ignore bicycle bottom bracket and derailleur pulley performance and continue to pump out under-performing products that sap wattage from riders who are working like mad to get faster. You have the BBInfinite bottom bracket with Ceramitechs already, and you've experienced the tremendous gains. It's time for another step forward toward your goal.

WARRANTY:

BBInfinite Ceramitech pulleys have a 1-Year warranty.
