SRAM XX1 Eagle AXS Upgrade Kit black

This SRAM Upgrade Kit is compatible with XX1 Eagle drivetrain components (X-DOME Eagle cassette, crank and chain) and replaces rear derailleur and shift lever with AXS electronic components.

Derailleur
More than a mechanical derailleur with a battery and a motor bolted on, 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. Instantaneous shifts from a single touch even while under World Cup-winning chain loads recorded in the heat of racing and affirmed in the test lab. Tested to IP69K water and dust proofing standard so whatever race day brings, you’re ready.

Controller
It’s simple. It’s about performance. The pure shifting performance of Eagle AXS is the real difference maker. Shift under load, over the roughest terrain, uphill, without changing your grip on the bar. Eagle AXS changes your level of control on the bike when you’re under pressure and pushing hard into the red. But more than that, it changes your relationship with the bike. No cable, housing or wires to manage opened up design and engineering possibilities with the Eagle AXS controller. Helping SRAM pioneer a completely new shifting experience with new ergonomic touchpoints that take just enough effort to press. Touchpoints that are totally customizable to your preferences, allowing you to choose which button does what through the AXS App.

Battery Charger
On the road or at home, the SRAM battery charger contains everything you need for re-charging your eTap or AXS batteries.

The AXS App
The AXS App is the mobile component software with which you can program and personalize Eagle AXS according to your preferences. The app lets you customize controller assignments for shift commands and your electronic reverb seat post directly from your mobile phone. Turn your left controller up or down. Assign your AXS-enabled reverb a button that's most intuitive for you. For the first time, AXS gives the driver the digital freedom to freely customize, personalize and enhance the operation. So you can create your own Eagle AXS "fingerprint".
