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™
The revolutionary machined design of the X-DOME™ cassette uses the same grueling manufacturing techniques that produced the PowerDome™ road cassette. With X-DOME™, nine of the cogs are CNC machined together out of a single block of billet steel, creating an incredibly lightweight, precise and strong cassette.

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 2×11 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.
