CeramicSpeed Alpha RS OSPW for SRAM RED/Force
The CeramicSpeed Alpha RS OSPW for SRAM RED/Force is the most advanced oversized pulley wheel from CeramicSpeed. Built for riders who demand the most efficient drivetrain possible, this system combines cutting-edge design with premium materials. Featuring a lightweight carbon fiber derailleur cage and redesigned shape, the Alpha RS OSPW is lighter and stiffer than ever. The updated cage design not only improves aesthetics, but also makes the derailleur cage stronger. This provides better shifting, especially under load.
Additionally, this OSPW features premium ceramic bearings and 15T upper and 19T lower oversized pulleys. This minimizes chain articulation which reduces drag and improves chain life. The Active Debris Remover shields also make it virtually impossible for debris to enter the bearings. Whether you race, train or simply want the best, the Alpha RS OWSP is a premium upgrade for SRAM RED or Force rear derailleurs.
Please note, it is recommended to use a new chain as the CeramicSpeed OSPW system requires a longer chain than the stock derailleur cage.

Considerations
This is a premium component that has a high cost associated with it. In addition, we have found that CeramicSpeed OSPWs perform best when they are properly maintained (cleaned and greased), so this setup is best for someone who maintains the condition of their bike’s drivetrain.
Advice From Our Staff
We believe this is a perfect choice for road cyclists, time trialists or triathletes who are looking to maximize drivetrain efficiency. Our team uses this OSPW on SRAM RED drivetrains and are happy to report that it shifts like the stock derailleur cage, so there is no loss in shifting performance. This is a great upgrade if you are looking for maximum efficiency or an aesthetic upgrade for your drivetrain.
