The product comes with both CeramicSpeed Standard and Coated pulleys with a 6 years warranty on the coated version and 4 on the standard version.

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.
