Technologies
X-SYNC™
SRAM’s X-SYNC™ technology features tall, square-shaped teeth that engage the chain earlier and more securely than traditional chainring designs. The narrow tooth profile and mud-clearing recesses improve chain retention, reduce wear, and maintain reliable performance even in muddy riding conditions.
Eagle™
Eagle™ is SRAM’s advanced 1x drivetrain platform, designed to be lighter, stronger, and easier to use than traditional multi-chainring systems. It offers a massive 520% gear range, delivering climbing capability comparable to many 2x drivetrains while maintaining the simplicity of a single chainring.
Cage Lock™
The integrated Cage Lock™ mechanism makes wheel removal, installation, and chain maintenance much easier. Simply push the derailleur cage forward and lock it in place to create chain slack whenever needed.
ROLLER BEARING CLUTCH™
The ROLLER BEARING CLUTCH™ minimizes chain slap and derailleur movement, providing quieter operation, improved chain retention, and more consistent shifting over rough terrain.
X-ACTUATION™
Developed specifically for SRAM 1x drivetrains, X-ACTUATION™ delivers crisp and consistent shifting across the entire cassette, ensuring reliable gear changes under all riding conditions.
X-HORIZON™
The X-HORIZON™ rear derailleur features a straight parallelogram design that limits movement to the horizontal axis, eliminating ghost shifting while reducing shift effort. Its optimized pulley offset maintains a consistent chain gap across the cassette for faster, smoother, and more accurate shifting.
