C-Bear OCM Derailleur Pulleys - Full Ceramic Bearings | 12-speed | for Shimano Dura Ace R9250

For the Shimano Dura Ace R9250 12-speed rear derailleur, the manufacturer C-Bear Ceramic Bearings created the OCM shift wheels with full ceramic bearings. In addition, they are larger than the original shifting wheels, from where the name is derived: OCM = Original Cage Max. Thanks to the enlargement they increase the perfomance of your drive significantly. Gear wheels are the fastest rotating bearings on your bike. A modification to ceramic bearings is therefore the most effective upgrade.

C-Bear Ceramic Bearings is a Belgian bearing specialist for ceramic ball bearings with the best smooth running properties, durability and accuracy of fit. All bearings work without additional spacers and washers.
