The Evolution of 1x Chain Retention

The SRAM X-SYNC 2 Eagle Direct Mount Chainring is the result of exhaustive research into how chains wear and interact with drivetrains. Designed specifically for the high-torque demands of 12-speed Eagle systems, this chainring moves beyond traditional designs to offer a smoother, more efficient pedal feel even in the most grueling trail conditions.

The core of this performance is the X-SYNC 2 tooth profile. Unlike the original boxy tooth shape, these aggressive, positive-rake teeth resemble a shark’s dorsal fin. This geometry allows the chainring to "hook" the chain earlier for maximum retention while letting it glide off seamlessly at the bottom of the stroke, significantly reducing friction, noise, and vibration.

Key Features:

• X-SYNC 2 Technology: An advanced tooth design that increases chain retention and wear life while clearing mud, grit, and grime more effectively.

• 3mm Boost Offset: Specifically engineered for Boost 148mm rear hub spacing to ensure a perfect 52mm chainline and optimal shifting performance.

• CNC-Machined Aluminum: Crafted from lightweight and durable aluminum to provide the rigidity needed for explosive sprints and steep technical climbs.

• Direct Mount Interface: Simplifies your setup by removing the need for a separate spider and bolts, resulting in a stiffer, lighter drivetrain.

• Eagle Ecosystem Compatibility: While optimized for 12-speed Eagle chains, it is also backwards compatible with SRAM 11-speed drivetrains.
