The OSPW X System reduces friction 35-40% over stock pulley configuration. The lightweight custom molded carbon fiber cage ensures durability. This design allows the use of the same length chain as stock pulleys. 

The 14-tooth upper and 18-tooth lower pulley profiles ensure stable chain retention without added drag. 

The OSPW X System is developed, designed and handbuilt in Denmark - and test proven globally. 

Only compatible with 1X specific derailleurs.

OSPW Compatibility

Notes:
• Adjustment of spring tension can allow for customization of user experience. Higher spring tension can focus on chain rentention & crisp shift response. Lower spring tension will reduce chain drag and improve overall efficency.
• The CeramicSpeed OSPW cage design has been tested for aerodynamic impacts in multiple wind tunnels. No measurable adverse aerodynamic impacts were measured through a variety of yaw angles.
• Shimano Ultegra R8000 GS, R8050 GS, and 105 derailleurs are not compatible with any CeramicSpeed OSPW system.
• SRAM Rival, & SRAM Apex derailleurs are not compatible with any CeramicSpeed OSPW system.
