DescriptionMore than a mechanical derailleur with a battery and motor, the Eagle AXS rear derailleur is the intelligent heart of the entire AXS ecosystem. Its shorter cage offers 10mm more ground clearance, increased chain wrap, and a more tucked-in position compared to mechanical Eagle. Shifts are instantaneous from a single touch, even under the massive chain loads seen in World Cup racing. With IP69K water and dust protection, this derailleur performs flawlessly no matter what race day throws at you.
