We built the incredible new XX1 Eagle drivetrain to work quietly, intuitively, precisely and perfectly. Whether you’re an hour and twelve minutes into a World Cup XC or, just about to hit the top of Pearl Pass - XX1 Eagle is ready for that and every place in between.
This cross-country-optimised drivetrain combines our newest generation of SRAM 1x drivetrain technological advancements with lightweight materials.
With a greater gear range of 500%, XX1 Eagle gives you smoother, more precise shifts with greater durability for long lasting performance so you can spend more time in the gear you want.
XX1 Eagle just rewrote the rules of freedom.

Features:
Shifter:
Tucked neatly beneath your handlebars, the XX1 Eagle X-ACTUATION trigger shifter is the nerve centre of the Eagle drivetrain. Its internal works have been updated to include a 12th gear, and improved to enhance trigger feel, precision and durability. Whether you’re 3 laps into your race or 150 days into your season, the XX1 Eagle trigger shifter is your faithful 1x touch point.
• New mechanism creates a smoother and more precise shifting system with exceptional reliability
• Carbon trigger and cover reduce weight
• Customisable setup via the adjustable pull-lever and MatchMaker X
Rear Derailleur:
This new derailleur not only answers the Eagle drivetrain’s need for greater capacity, but is also the next evolution of our proven, 1x-specific X-HORIZON design. The larger, 14-tooth X-SYNC lower pulley, allows 10- to 50-tooth cassette capacity in this compact design, and also adds to Eagle’s overall smooth-peddling feel. Our new, Type-3 ROLLER BEARING CLUTCH features a smoother torque curve for a quieter, more consistent operation and feel. CAGE LOCK has been moved back and out of the way, protecting it from trail debris. A redesigned, robust mounting system further improves the Eagle derailleur’s performance and overall durability.
• Completely redesigned rear derailleur incorporating our proven X-HORIZON design and new Type-3 ROLLER BEARING CLUTCH technology
• Re-engineered mounting system and repositioned CAGE LOCK add robustness
• Eagle pulley technology provides greater efficiency, crisper shifting and quieter operation
• Carbon cage and lightweight hardware make it light and tough
Chainset:
True competitors are always looking for a performance advantage - a relentless pursuit of equipment that is lighter, stiffer and stronger. To create the best drivetrain possible, we started with a completely reengineered crankset design. Our all-new XX1 Eagle crankset is the lightest, stiffest and strongest on the market. A special hollow internal architecture, combined with our proprietary CARBON TUNED lay-up, allows us 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 a new Eagle direct mount chainring, and as an integral part of the Eagle drivetrain, the new XX1 Eagle crankset puts more focused power into every ride.
• The lightest, stiffest, strongest crankset available
• All-new crank-arm design optimised for cross-country and trail applications
• All-new SRAM CARBON TUNED crank technology provides extreme stiffness and light weight
• All-new chainring technology is designed specifically for Eagle chains and drivetrains
• The X-SYNC 2 chainring provides significantly quieter performance, with better mud clearing and extraordinary durability
• Crank arm length: 175mm
• Chainring size: 32t
Chainring:
The radical new look and feel of our X-SYNC 2 Eagle chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. We subjected every size of chainring to untold environmental and mechanical tortures, abuse and neglect, in both lab and real-world settings, to come up with a chainring that would augment the Eagle drivetrain’s performance in all conditions. The longer, positive-rake tooth shape has been designed to work perfectly with the new Eagle chain to increase chain retention and overall pedalling efficiency, while decreasing friction, noise and wear.
• X-SYNC 2 chainring design increases chain retention, wear life, and reduces friction and noise.
• Designed to be used with Eagle chain
Cassette:
Take a quick look at the new X-DOME Eagle cassette. The last dangling shred of an argument in favour 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% 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
• All-new shifting features create a smoother, quieter system with enhanced inboard and outboard shift performance
• XD driver body compatible
• Ratio: 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50
Chain:
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.
• Groundbreaking new chain design and technology
• The Eagle chain has been completely re-engineered, and is produced with new manufacturing technology
• All-new Eagle PowerLock chain connector with FLOWLINK technology provides better chain-guiding and increased longevity
• The XX1 Eagle chain is the quietest, strongest and most wear-resistant chain in the world
• Unique features and design also provide significantly improved wear resistance on Eagle cassettes and rings
