Keep your 12-speed Eagle drivetrain running at its best with a genuine SRAM X-SYNC Eagle 104BCD replacement chainring. The 104BCD 4-bolt pattern fits a wide range of SRAM and compatible MTB cranksets, making these a go-to upgrade or replacement for Eagle builds.

Highlights

• 104BCD 4-bolt mount — fits most SRAM and compatible MTB cranksets
• X-SYNC 2 tooth profile — alternating wide-narrow teeth lock the chain on under load
• Designed for SRAM Eagle 12-speed drivetrains (GX Eagle, NX Eagle and compatible)
• Hard-anodised aluminium for durability and weight savings
• Available in multiple tooth counts

X-SYNC 2 tooth engagement

X-SYNC 2 chainrings use an alternating wide-narrow tooth profile shaped to match both inner and outer chain link gaps. The chain snaps on quickly and stays put through rough terrain and hard efforts, dramatically reducing the risk of chain drop without needing a chain guide.

Fit and compatibility

Designed for SRAM Eagle 12-speed chains and drivetrains. The 104BCD 4-bolt pattern fits SRAM GX Eagle, NX Eagle and many compatible aftermarket cranksets. Confirm tooth count and crank compatibility before ordering. Not compatible with non-Eagle (10 or 11-speed) chains.
