X01 Eagle Has Landed

If your bike is already equipped with a SRAM Eagle drivetrain, the X01 Eagle AXS Upgrade Kit allows you to make the switch to wireless electronic shifting without needing to buy the entire AXS groupset. The kit includes the XO1 Eagle AXS derailleur with battery, the Eagle AXS shifter (SRAM calls it the Controller), and a battery charger with charging cable. These components are all you need to make the switch, which means you can continue using your existing Eagle cranks, cassette, and chain to save yourself a bit of extra cash on the upgrade.

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 adjustment. 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.


  • Convert your Eagle drivetrain to wireless shifting with this kit
  • Includes derailleur, battery, shifter (controller), and charger
  • Enjoy crisp, consistent shifting with low maintenance
  • Keeps your bike clean with completely cable-free construction
  • All new shifters are fully programmable and intuitive to use
  • Derailleur sits with 10mm more clearance than mechanical version
  • Overload clutch disengages on impact to protect derailleur motor
  • Easy to use AXS smartphone app lets you monitor and program the system
  • Includes derailleur, controller, bar clamp, battery, charger, charger cable, B gap adjustment gauge
  • Available in Lunar or Red colorways

    You don't NEED this

    You don't NEED AXS...but once you have it, there is no going back. I work in technology so I definitely appreciate innovation and products that greatly improve the user experience. I am fortunate to be able to purchase this upgrade kit, and fully acknowledge that even at the discount BTD is offering it at, it is very much a luxury spend. But wow it's a game changer. I just applied for a home equity line of credit so that I can outfit my road and gravel bikes with this e-bling. Kidding. When I first saw AXS come out a couple years back, I figured there was NO WAY I would ever own it...just can't justify that kind of cash over a mechanical set. I was wrong. The shifting is UN-FREAKING-BELIEVABLE. On my first ride, I had some issues with indexing that I literally fixed on the fly. I think the best part is being able to shift a bit more effectively under load. And if you're wondering it will work FINE with a Shimano crankset and 12 spd chainring.

    mandatory on FS

    I have finally gave up on cable actuated shifting on full suspension. especially long travel, the cable routing is just too much to deal with. this went on my Ibis Ripmo that had XX1 mechanical. i have XX1 axs on my Blur, and X01 transmission on my Pivot. I like the shifter in this upgrade the most! And it shifts just as well as the XX1. If you have 12 speed eagle already and the cash this is a great upgrade.

    AXS upgrade

    Upgraded my Trek Farley 9.6 from mechanical to Eagle AXS. Extremely easy install and flawless shifting; I can�t ask for anything more.
