Sram: More than a mechanical derailleur with a battery and a motor bolted on, the Eagle AXS™ derailleur is the brain of the whole AXS™ system. Trim it at set-up for zero rub, making the near-silent operation of Eagle™ even more stealth – all while improving drivetrain longevity. 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.THINGS TO REMEMBERXC focus and trail readyCarbon cageTi hardwareRainbow colorwayEagle™ technologyOverload Clutch protectionAXS™ enabled componentry software that makes it possible to both program and personalize new SRAM and RockShox componentsSystem is completely water and dust proof to IP69KEagle AXS™ is designed to work with X-DOME™ Eagle™ cassettes only, providing the most precise, silent, and reliable shift performance available.Battery sold separately SPECIFICATIONSSpeed (RD): 12sCable pull ratio: n/aCage (RD): n/aMax tooth: 52Color (RD): BlackPulley bearings material: SteelCage material (RD): Carbon
