SRAM X-Sync 2 Eagle V2 Chainring in Fat Bike -4mm Offset is a direct-mount, 3-bolt aluminum chainring built to keep modern 1x drivetrains running quieter and more securely in demanding conditions. The X-Sync 2 narrow-wide tooth profile uses a longer, positive-rake shape that’s designed around the SRAM Eagle chain, improving chain retention under load while helping reduce friction, noise, and tooth/chain wear over time.
X-Sync 2 narrow-wide tooth profile - Designed to increase chain retention for 1x setups, especially when pedaling hard through rough terrain
SRAM Eagle and 11-speed Powerchain compatibility - Works with SRAM Eagle chains and compatible 11-speed Powerchain chains for straightforward drivetrain matching
Fat bike -4mm offset - Built to support proper chainline on compatible fat bike crank setups using SRAM’s 3-bolt direct-mount standard
Direct-mount 3-bolt interface - Clean, rigid mounting for precise chainring alignment and simplified service
Includes mounting hardware - Ships with 3 chainring bolts for complete installation
Compatibility note - Not compatible with XX T-Type bash guards
