The rumours were true, and the first 1 x 12 group from SRAM has been officially unveiled. Dubbed Eagle, it runs a massive 10-50t cassette for a 500% gear range and spells the end of the front derailleur altogether from SRAM’s off-road range. Even GripShift is back! And how good does that gold cassette look?
Official Press Release:
Today, Thursday March 24th SRAM is proud to unveil the new SRAM EAGLE™ XX1 & X01 DRIVETRAINS

SRAM introduced the first ever, purpose built 1x drivetrain, and is the absolute leader in 1x technology and innovation. We have manufactured, tested and ridden hundreds of thousands of SRAM 1x™ drivetrains, and have capitalized onthe lessons learned from our experience to createall new drivetrains with Eagle™ Technology. Eagle™ drivetrains provide unparalleled performance, enhanced toughness and durability, and the freedom of a 500 percent gear range.
Introducing SRAM Eagle™ Technology, our most advanced and highest-performing drivetrains to date. The new XX1 and X01 drivetrains, featuring Eagle™ Technology, are collections of components that have been engineered for a whole new level of ride quality and integration. These drivetrains have not only been refined, we have torn them apart, built them up, tested, tweaked, engineered and tested again. Eagle™ Technology delivers a drivetrain that is smoother, simpler, more durable and quieter than anything you’ve ever ridden. Add to that Eagle’s massivegear range, and you have greater freedom to ride how you want, where you want. Performance, durability, simplicity, range, freedom: Introducing Eagle™, only from SRAM.

XX1 Eagle™
New Rules
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-optimized drivetrain combines our newest generation of SRAM 1x™ drivetrain technological advancements with lightweight materials. With a greater gear range of 500-percent, 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.

XX1 Eagle™ Chain
Silence
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.
THINGS TO REMEMBER
· Eagle™ represents our newest 1x drivetrain technologies
· Eagle™ is a lighter, tougher, quieter, more durable and more precise
· Eagle™ features all-new 1x components, engineered for even greater durability and performance
· Eagle™ has a significant weight advantage over other drivetrains—XX1 Eagle™ weighs up to 300 grams less than 2x drivetrains with similar gear range
· Eagle™ technology allows an expanded, optimum, 500-percent gear range—a 20-percent increase over our other 1x drivetrains
FEATURES AND BENEFITS
· Groundbreaking new chain design and technology
· The Eagle™ chain has been completely re-engineered, and is produced with new manufacturing technology.
· All-new Eagle™ Power Lock 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

XG-1299 Eagle™ Cassette
Freedom
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.
FEATURES AND BENEFITS
· 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

XX1 Eagle™ Rear Derailleur
PURPOSE
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-pedaling 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.

Eagle™ Chainring
Integrity
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 pedaling efficiency, while decreasing friction, noise and wear.

X-SYNC™ 2 chainring design increases chain retention, wear life, and reduces friction and noise.
