CeramicSpeed OSPW X Alpha for SRAM RED E1 XPLR
The CeramicSpeed OSPW X Alpha for SRAM RED E1 XPLR rear derailleurs is an oversized pulley wheel system designed specifically for gravel bikes. Made for riders who demand the most efficient drivetrain possible, this system combines cutting-edge design with premium materials. It features composite teeth to make it more durable and uses solid pulley wheels to eliminate debris entering the derailleur cage and clogging the system. Featuring a reinforced carbon fiber derailleur cage and redesigned shape, the X Alpha 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 14T upper and 20T 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 E1 XPLR rear derailleurs.

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 great choice for gravel and adventure riders that are looking for maximum drivetrain efficiency. This OSPW uses only the best materials to save watts. While it does not feature SRAM’s Magic Pulley Wheel to clear debris, the solid pulley wheel discs eliminate this issue.
