SRAM X01 Eagle AXS Dub Boost 12 Speed Electronic Groupset

At a glance the SRAM X01 Eagle AXS DUB Boost Mountain Bike Groupset brings the real benefits of wireless electronic shifting to the mountain bike. On a deeper level, it offers discerning riders unprecedented personalisation and control of the drivetrain,on the bike and off. Deepening the relationship between machine and rider. This addition to the Eagle ecosystem enhances capability. Removes complexity. And provides riders an experience like never before.

Both XX1 Eagle AXS and X01 Eagle AXS combine the proven, dedicated 1x backbone of Eagle with a connected wireless electronic derailleur and controller. With completely new inputs at the bar that initiate a shift with a touch. It’s an all-new derailleur that’s specifically designed and optimized to be motor-driven instead of cable-actuated, to truly leverage what this allows. AXS powered components enable customization and scale to an individual rider’s liking via the AXS App.

The pure shifting performance of Eagle AXS is the real difference maker. Shift under load, over the roughest terrain, uphill, or without changing your grip on the bar.

Bolt it on. Set three limit screws. Press the pairing buttons. And go. Eagle AXS is trimmed and adjusted electronically for a perfect chainline. There is no additional effort to shift or idiosyncrasies to learn. AXS unlocks an entirely new way to personalize the key interface with your bike – all controlled from your phone via a simple AXS App. Unless you’re looking to set it and forget it. Because you can do that too.

There’s an element of the unknown when it comes to running new trail and racing blind. Enduro spec follows suit. X01 Eagle AXS utilizes the proven backbone of SRAM 1x. 500-percent gear range. More secure and longer wearing X-Sync 2 chainring. The resilience of an aluminium cage paired with the connected components of Eagle AXS. Ready for the new gen of super bikes.

Eagle AXS Derailleur

The Eagle AXS derailleur is the heart of the whole AXS system. 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.

Eagle AXS Controller

No cable, housing or wires helped pioneer a completely new shifting experience. Allowing you to choose which paddle does what through the AXS™ App. Choose from: Inboard shift. Outboard shift. Dropper.
