Purpose-built for SRAM's AXS road cranksets, these X-SYNC 107BCD chainrings bring the wide-narrow tooth engagement system to road drivetrains. The asymmetric 107BCD bolt circle is unique to SRAM's AXS road crank platform, ensuring precise chain line and shift ramp positioning from the start.

Highlights

  • 107BCD asymmetric bolt circle — fits SRAM AXS road cranksets
  • X-SYNC wide-narrow tooth profile keeps the chain locked on under sprint loads
  • Hard-anodised aluminium — lightweight and wear-resistant
  • Compatible with SRAM AXS 12-speed road chains
  • Available in multiple tooth counts

Wide-narrow teeth on the road

X-SYNC tooth shaping alternates wide and narrow profiles to match inner and outer chain link gaps. This tight mesh reduces chain lift and audible chain slap, keeping the drivetrain quiet and efficient whether you're in the drops at race pace or grinding a long climb.

Fit and compatibility

Designed for SRAM AXS 12-speed road drivetrains using the 107BCD asymmetric crank pattern. Confirm tooth count against your gearing requirements. Not compatible with older SRAM road cranks using symmetric BCD patterns.
