Sram XX Eagle AXS Transmission

For racing. Dream bike worthy.

This is where imagination, innovation and unprecedented performance meet. The drivetrain of dreams, XX Eagle Transmission has been designed and engineered into tangible technology for the world’s most demanding on the widest range of builds. This is the next level of what’s possible with human only or the added watts of a motor. This is the zenith.

Impossible shifts made possible.

Forget the old limits of performance, this is the only system which maximizes the capabilities of an E-MTB. With hard-wearing components and shifting that literally gets better with more pedaling power, XX Eagle Transmission is ready for the additional outputs of next-gen drive units. It’s simply in a class of its own. 

Seismic shifts.

Say goodbye to anticipatory shifts where the terrain forces your hand. Eagle Transmission gives you the power to shift when and how you want. For the first time, you can pedal at full output while you shift – inboard or outboard. Cassette Mapping provides precise shift points while X-Sync tooth profiles maximize chain engagement, so no effort is wasted in the system to translate yours into one thing – propulsion.

Champions choose carbon.

With multiple World Championship medals, EWS series wins and Olympic gold medals to its namesake, SRAM carbon cranks are proven at the pinnacle. The XX Eagle DUB crank is engineered around a foam core to give both incredible strength and maximized stiffness. Ready for race days or big days on big terrain with swappable direct mount chainrings and first-of-its-kind replaceable and removable bash guards. Nothing comes close to matching the legacy and performance of XX.

The power within.

Built for the most exacting riders on the trail, the XX Eagle Transmission crankset is power meter ready with the superlight DUB-PWR system seamlessly housed within the crank’s spindle. It’s the lightest, cleanest integration of Quarq’s reliable and accurate power measurement, fully compatible with any T-Type direct mount chainring. A minimalist setup for riders who want to maximize their potential, and connect to AXS enabled components.

One, powerful ring.

Taking optimization even further, XX T-Type Direct Mount chainrings are the most advanced E-MTB specific chainring in existence. Bold claim. But with fitment perfected for Bosch, Brose, Shimano – and soon to add TQ & Fazua motors – nearly every E-MTB can run the most secure chain retention tech, at the lightest weight. Pairing with a SRAM crank and GapCap creates a seamless integration between crank and ring. This is the best shift under load and the most striking aesthetics. This is E-MTB specific at its best.

Even more refined for dream builds. Still no excuses.

Since inception, XX left no excuses on the racetrack or mountain. This is the highest performing group set with the full range of ultra-premium build options – all with carbon cranks. Enduro tough. XC light. Super bike ready. Flawlessly shifts with the increased watts of E-MTB systems. With versatility of XX Eagle Transmission, the choice is all yours.
