The CyclingCeramic OSPW Pro 2.0 derailleur cage is an upgrade that improves the performance and efficiency of Ultegra & Dura Ace rear derailleurs.

The CyclingCeramic Oversized Pulleys are equipped with aluminum pulleys, combined with a light but strong carbon back plate and an aluminum front plate. This material mix ensures significant weight savings and offers a robust construction. Perfect for the demands of high performance road cycling. The sleek, aerodynamic design of the wheels contributes to better drag of your drive train.

The high-quality ceramic bearings significantly reduce friction during gear changes, leading to a smoother drive and noticeable energy savings. This allows for a more efficient pedaling motion and helps you optimize your performance while climbing and sprinting.

The CyclingCeramic pulley wheels have been extensively tested by Frictions Facts, an independent laboratory that specializes in measuring friction and efficiency of drive trains in cycling. The test results show that CyclingCeramic’s ceramic bearings are among the fastest on the market, with an extremely low friction value of only 0.033 W.
