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 520%, which is equal to 2x11 drivetrains.

X-GLIDE 2 is the 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. 

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