SRAM XG 1299 Eagle cassette 12-speed 10 52 teeth copper

The air is thinnest at the top. That’s precisely where the XX1 Eagle excels. Even within SRAM’s expanded Eagle ecosystem, it’s the groupset for world-class race bikes and absolute dream bikes. Offering top-level performance and compatible with all Eagle shifting systems, the XX1 Eagle drivetrain will remain incredibly precise, intuitive, and quiet, now and in the future.

With optimized chain retention thanks to a new derailleur cage architecture, the XX1 Eagle maintains its position at the pinnacle of mountain bike drivetrains. On top of that, there’s a real boost in aesthetics: with the XX1 Eagle, SRAM launches its coordinated Eagle color system. Shifters, crankset, and derailleur all follow the same XX1 Master color theme, which can be combined with any cassette and chain color to personalize the bike’s design concept—whether it’s black, gold, rainbow, or the brand-new copper. The XX1 Eagle remains the lightest groupset in the Eagle ecosystem. It now boasts an increased 520 percent gear range thanks to our new 10-52 tooth cassette. Stronger riders can choose a larger chainring for more top speed without sacrificing climbing ability.

eagle
Eagle technology represents SRAM’s latest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier-to-use drivetrain. Eagle features brand-new 1x components that deliver even greater durability and performance while offering a significant weight advantage compared to other drivetrain solutions. Eagle technology also boasts an expanded gear range of 500%, making it comparable to 2×11 drivetrains.

XD Driver Body
XD is a drive body design for cassettes that allows the use of a small 10-tooth sprocket and improves contact with the cassette.

X-DOME
X-DOME technology creates an incredibly lightweight, precise, and robust cassette. The open design sheds dirt more effectively, providing smoother shifting performance and extended component lifespan.

X-GLIDE 2
The X-GLIDE 2 is the next generation of our X-GLIDE technology. It has been specifically optimized for our EAGLE 12-speed cassette for fast and precise shifting performance in all gears. The X-GLIDE technology increases chain tension on the larger sprockets.
