SRAM GX Eagle AXS Rear Derailleur - 12-Speed, Long Cage, 52t Max, Lunar

Not only does the SRAM GX Eagle AXS Rear Derailleur get the job done, it features everything you have come to expect from SRAM's AXS connect components . It's able to shift on command, whether that's under climbing load, or sprinting to the stage finish. The derailleur is smart enough to protect itself thanks to its incredibly resilient Overload Clutch. Engineered with a variety of rider preferences in mind, it is compatible with the expanded range 10-52t cassette as well as the 10-50t cassette.
