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.
