It's an all-new derailleur that's specifically designed and optimized to be motor-driven instead of cable-actuated. AXS powered components enable customization and scale to an individual rider's liking via the AXS App. 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. The Eagle AXS derailleur is smart enough to protect itself thanks to its incredibly resilient Overload Clutch. In the event of an impact, the motor gearbox disengages, giving the derailleur freedom to move, and instantly returns back to its position for a seamless experience for the rider. The system is tested to IP69K water and dust proofing standard for creek crossings, mud splatterings and the resulting post-ride pressure washings.Features:- Enduro focus and trail ready- Forged aluminum cage- Stainless hardware- Black/Polar colorways- Eagle technology- Overload Clutch protection- AXS enabled componentry software that makes it possible to both program and personalize new SRAM and RockShox components- System is completely water and dust proof to IPX7- Battery sold separatelySpecifications:- Speed (RD): 12- Max tooth: 52- Pulley bearings material: Steel- Cage material (RD): Aluminum- Part Weight: 373 g
