SRAM XX1 Eagle AXS 12-Speed Rear Derailleur

More than a mechanical derailleur with a battery and a motor bolted on, the SRAM XX1 Eagle AXS 12-Speed Rear Derailleur is the heart of the whole AXS system. It features a shorter cage for 10mm more ground clearance, with more chain wrap on the cassette to sit slightly further forward, and further inboard from mechanical Eagle. Instantaneous shifts from a single touch even while under World Cup-winning chain loads recorded in the heat of racing and affirmed in the test lab. Tested to IP69K water and dust proofing standard so whatever race day brings, you’re ready.
