SRAM Eagle GX 12-Speed Rear Derailleur

Strong and versatile, the SRAM Eagle GX 12-Speed Rear Derailleur is designed to deliver smooth shifting for your cross country, trail, or enduro bike. Designed for use with up to the latest 52t SRAM cassettes, it is compatible with all other components from the Eagle mechanical ecosystem. An all-new cage design improves chain management, providing better chain retention for precise shifting. A roller bearing clutch reduces chain slap for a silent ride on rough trails, without sacrificing shifting performance.
