SRAM Xx1 Eagle Axs Upgrade Kit

Straight from the World Cup cross country circuit, the XX1 Eagle AXS drivetrain is now available for privateer racers and die-hard XC riders to enjoy the low maintenance and crisp, reliable shifting of a wireless electronic drivetrain. If your featherweight race steed is already equipped with an Eagle 12-speed drivetrain, the XX1 Eagle AXS Upgrade Kit is all you need to make the switch to wireless shifting. The kit includes the XX1 Eagle AXS derailleur with battery, the Eagle AXS shifter (called the Controller by SRAM), and a battery charger, allowing you to use your existing Eagle cranks, cassette, and chain to save considerable money compared to buying the groupset as a whole.

The truth is, electronic shifting is actually easier to maintain than its mechanical counterpart. AXS shifting removes the hassle of routing cables and housing through the frame, and you'll never have to worry about cable stretch or wear. This means crisp, responsive, consistent shifting that rarely needs any adjustments. You'll also enjoy a cleaner cockpit thanks to one less cable, and you can customize the buttons on the shifter to do exactly what you want. Setup is as simple as mounting the derailleur and setting limit screws, installing the shifter, and then powering on the system and pairing the two.

Compared to mechanical Eagle groupsets, the Eagle AXS derailleur has been contoured around the frame design a bit more, which translates to increased chain wrap, improving both load distribution and durability, reducing wear and tear on your chain and cassette for better longevity of components. This new positioning also offers a whole 10-millimeters of increased clearance over mechanical Eagle rear derailleurs, meaning you're less likely to encounter interference or damage while riding.

The XX1 Eagle rear derailleur provides instantaneous shifting from a single touch, even under the heaviest of loads, and features a shorter cage that allows for 10mm more ground clearance and more chain wrap on the cassette. The Eagle AXS controller offers a unique wireless shifting experience with ergonomic touchpoints that are customizable to your preferences through the AXS App, allowing you to choose what each button does.
