SRAM Force Rival XPLR eTap AXS Rear Derailleur Inner Cage with Screws

SRAM rear derailleur cage assembly parts for rebuilding SRAM rear derailleurs.

The CeramicSpeed Oversized Pulley Wheel System provides optimization and increased efficiency of the rear derailleur through its extremely low-friction bearings and unique overall design.

CeramicSpeed’s OSPW Aero system has been developed in close collaboration with one of the world’s leading aerodynamicists. The development process behind the OSPW Aero spanned over two years, where extensive wind tunnel testing influenced multiple design iterations. The end result is an entirely new cage structure wrapped around our existing mechanically optimized design.
