Eagle AXS

At a glance, Eagle AXS™ brings the real benefits of wireless electronic shifting to the mountain bike. On a deeper level, it offers discerning riders unprecedented personalization and control of the drivetrain, both on the bike and off. Eagle AXS combines the 1x backbone of SRAM’s Eagle™ platform, with a connected wireless electronic derailleur and controller. The pure shifting performance of Eagle AXS™ sets it apart, allowing you to shift under load, over the roughest terrain, uphill, or without changing your grip on the bar. This addition to the Eagle™ ecosystem enhances capability, removes complexity, and provides riders an experience like never before imagined.

The Eagle XX1 AXS™ Groupset

SRAM’s XX1 Eagle AXS™ Groupset provides the complete Eagle AXS™ experience, with wirelessly connected electronic components. Using the lightest weight Eagle™ drivetrain parts, this XC focused system is the pinnacle of performance. The groupset includes the XX1 Eagle DUB crankset with a long-wearing X-SYNC 2 chainring, the AXS™ electronic controller and electronic rear derailleur, and a wide-range Eagle™ 12 speed cassette and chain. All components in this groupset operate together to provide exceptional 500% gear range with the simplicity of a 1x system.

The Eagle AXS™ Controller

The Eagle AXS™ controller pioneers a completely new shifting experience with ergonomic touchpoints that are totally customizable. Using the AXS™ app, you can choose which button does what. Choose from three functions: inboard shift, outboard shift, and dropper. It also features a power save mode to wake up after a single touch to save battery when not in use.

The Eagle AXS™ Rear Derailleur

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. It features a shorter cage for 10mm more ground clearance, and has more chain wrap on the cassette to sit slightly further forward. 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 to provide a seamless experience for the rider.

The AXS™ Advantage

AXS™—SRAM’s bike component integration system—takes wireless shifting to the next level for the Eagle drivetrain. AXS™ lets the rider adjust and personalize controller assignments for shift commands and your electronically activated Reverb dropper post right from the mobile app for total customization. It also allows you to mix and match Road and MTB components for a completely unique experience. For the first time, AXS™ introduces digital possibilities for riders to customize, personalize, control, and improve the ride.
