It is an entirely new derailleur, specifically designed and optimized to be motor-driven rather than cable-driven. AXS-powered components allow for customization and scaling to an individual rider's preference via the AXS app. It has a shorter cage for 10mm more ground clearance, with more chain wrap on the cassette to sit slightly further forward, and further inward than mechanical Eagle. The Eagle AXS derailleur is smart enough to protect itself thanks to the incredibly resilient Overload Clutch. In the event of an impact, the motor gearbox disengages, allowing the derailleur to move freely and instantly return to its position for a seamless rider experience. The system is tested to the IP69K water and dust resistance standard for creek crossings, mud splashes, and the resulting high-pressure washes after the ride.
