SRAM Eagle AXS - Technology For Simplicity
At a glance, Eagle AXS™ brings the real benefits of wireless electronic shifting to the mountain bike. On a deeper level, it offers discerning riders unprecedented personalization 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 imagined.
Pioneering upon a proven backbone
The XX1 Eagle AXS™ combines the proven, dedicated 1x backbone of Eagle™ with a connected wireless electronic derailleur and controller (shifter). With completely new inputs at the bar that initiate a shift with a touch. It is an all-new derailleur that is 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 (for Google Android and Apple iOS platform available).
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. 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.
SRAM XX1 Eagle AXS™ - XC spec and ready for the trail
Combining lightest weight materials and a 500-percent gear range. Featuring a more secure and longer wearing X-SYNC™2 chainring. The pinnacle of performance, paired with the connected components of Eagle AXS™.
SRAM XX1 Eagle AXS Type 3 X-HORIZON Rear Derailleur 12-speed
More than a mechanical derailleur with a battery and a motor bolted on, the Eagle AXS™ derailleur is the brain of
the whole AXS™ system. Trim it at set-up for zero rub, making the near-silent operation of Eagle™ even more stealth—all while improving drivetrain longevity.
It features a shorter carbon 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.
And of course it features SRAM's proven, 1x-specific X-HORIZON™ design. Large X-SYNC™ lower pulley, allows 10- to 50-tooth cassette capacity in this compact design, and also adds to Eagle's overall smooth-pedaling feel. The SRAM XX1 Eagle AXS™ derailleur uses both Type-3 roller bearing clutch and Overload Clutch. Type 3 roller bearing clutch is used to control cage movement and chain management. The Overload gearbox clutch protects the
derailleur’s wireless motor in the event of impact. The CAGE LOCK™ function allows for an easy servicing. A robust mounting system further improves the Eagle™ derailleur's performance and overall durability. Thanks to titanium hardware the weight could be further reduced.
A bit about the battery
Yes, Eagle AXS™ uses a battery. One that is removable for easy recharging after 20 hours of ride time*. One that only weighs 25g and is detachable with a single clip. One that is "hot swappable"" if needed—from derailleur to your Reverb AXS™ seatpost or even your SRAM RED eTap AXS™ road group. And it only takes an hour to charge.
Derailleur compatible with Eagle™-Cassette 10-50 teeth only.
SRAM XG-1299 Eagle Cassette 12-speed - Rainbow Color
Take a quick look at the new X-DOME™ Eagle™ cassette. The last dangling shred of an argument in favor of a mountain bike front derailleur is now officially dead. Designed for use with our proven, reliable XD™ driver body, this 12-speed, 10- to 50-tooth cassette offers an optimal 500-percent gear range at a considerably lighter weight than 2x systems. It carries with it the X-DOME™ architecture, which, independent tests have concluded, yields the strongest cassettes on the market. New shifting characteristics improve both, inboard and outboard shifting, as well as chain retention.
- SRAM's cassette manufacturing technology provides the greatest durability and lightest weight
- XD™ driver body compatible
- 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50
SRAM Eagle AXS Controller 12-speed
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 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. Choose from three functions: Inboard shift. Outboard shift. Dropper. Use one of the touchpoints to control your electronic Reverb AXS™ dropper seatpost. And the power save mode in the controller wakes up after a single touch to save battery when not in use.
The Secret Sprint Paddle
Beyond the controller’s standard paddle, an included "Secret Sprint" paddle oriented on the front-side of the controller near your index knuckle allows for quick shifts with virtually no change to your grip on the handlebar.

SRAM XX1 Eagle Boost DUB crankset with X-Sync chainring - LIGHTER. STIFFER. STRONGER.
True competitors are always looking for a performance advantage-a relentless pursuit of equipment that is lighter, stiffer and stronger. The XX1 Eagle™ crankset is one of the lightest, stiffest and strongest on the market. A special hollow internal architecture, combined with SRAM's proprietary CARBON TUNED™ lay-up, allows to build a lightweight and ultra-energy-efficient crankset perfectly suited for the high-wattage output and smooth style of cross country riding and racing. Teamed up with an Eagle™ direct mount chainring, and as an integral part of the Eagle™ drivetrain. The DUB (Durable Unified Bottom Bracket) crank spindle, which can be universally used in all common bottom bracket shells, also increases rigidity. The bearing play will be fine tuned with an adjuster ring. It is equipped with a X-SYNC™ 2 chainring providing significantly quieter performance, with better mud clearing and extraordinary durability.
SRAM XX1 Eagle Chain 12-speed - Rainbow Color
It might look normal from the outside, but the engineering inside this incredible new chain design that makes possible a gear range previously found only in 2-chainring drivetrains. And it's also the biggest contributor to the Eagle™ drivetrain's ultra-smooth, precise, durable and quiet performance. The Eagle™ chain's links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. HARD CHROME™ technology extends the chain's optimal performance life, and a Titanium Nitride coating on the Gold and Black models decreases corrosion and further reduces friction.
The Eagle™ PowerLock® chain connector with FLOWLINK™ technology provides better chain-guiding and increased longevity.
