CeramicSpeed OSPW X for SRAM Eagle AXS Transmission

The CeramicSpeed OSPW X for SRAM Eagle AXS Transmission rear derailleurs is made to push the efficiency of your MTB drivetrain. This system combines cutting-edge design with premium materials to improve your Transmission drivetrain’s performance. Featuring a lightweight carbon fiber derailleur cage and redesigned shape, the OSPW X is lighter and stiffer than ever. The ALPHA Disc pulley wheels use a narrow-wide tooth profile for additional durability and noise reduction. Made from solid aluminum discs, these pulley wheels eliminate debris from entering the system. Additionally, the carbon cage design not only improves aesthetics, but also makes the derailleur cage stronger. This provides better shifting, especially under load.

This OSPW also 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 OWSP X is a premium upgrade for SRAM Transmission rear derailleurs.

 

Product Details

Key Features of the OSWP X for SRAM Transmission

  • Oversized Pulley Wheels: Larger pulley wheels reduce chain articulation and increase efficiency.
  • Active Debris Remover: Redesigned dust shields make it virtually impossible for dust and dirt to enter the bearings.
  • CeramicSpeed OSPW X: Redesigned for improved stiffness and efficiency, this OSPW features a lighter and stiffer cage for improved shifting.
  • Premium Ceramic Bearings: Helps to reduce drag as your chain moves through the derailleur cage.
  • Clean Aesthetic: A visually sleek setup that improves the look of any bike.

Compatibility

The CeramicSpeed OSPW X works with SRAM Transmission rear derailleurs and SRAM T-Type chains. See Compatibility tab for more details.

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 upgrade for XC and trail riders who are looking to maximize their drivetrain efficiency. Although OSPWs are traditionally used on road or gravel bikes, these can help you minimize drag while also being an aesthetic upgrade for your drivetrain.
