SRAM Eagle X-SYNC 2 Chainring

The 3mm offset indicates this chainring is designed for Boost spacing, which is the standard for most modern mountain bikes with wider rear axle spacing. You should check your current chainring or crankset specifications to ensure your bike requires a Boost-offset ring to maintain proper chain alignment.

This chainring is specifically optimized for SRAM Eagle 12-speed chains. While it may physically fit other systems, the X-SYNC 2 tooth profile is engineered to work precisely with the geometry of Eagle chains to ensure optimal retention and quiet operation.

The direct mount interface attaches the chainring directly to the crank arm using three bolts, eliminating the need for a separate spider. This design reduces overall weight and simplifies maintenance, while also providing a stiffer, more direct connection for power transfer.

Yes, the X-SYNC 2 tooth profile is specifically shaped to reduce friction as the chain engages and disengages. By minimizing the metal-on-metal contact and improving how the chain sits on the teeth, it significantly reduces the noise typically associated with aggressive 1x drivetrains.

This chainring uses the SRAM 3-bolt direct mount standard. It is compatible with most SRAM Eagle cranksets, but you should verify that your specific crank model uses the 3-bolt interface rather than the newer 8-bolt standard.
