Technologies

XD Driver body
XD is a cassette driver body design that allows the use of a 10-tooth small cog and provides an improved interface with the cassette.

X-DOME
X-DOME technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.

Eagle
Eagle technology represents our newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 500%, which is equal to 2x11 drivetrains.

X-GLIDE 2
X-GLIDE 2 is next generation of SRAM X-GLIDE technology optimized for the EAGLE 12-speed cassette. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs.
