SRAM Rival 107BCD chainrings use X-Range gearing geometry — smaller inner and outer rings paired with a 10-tooth cassette start for an overall gear range that rivals a traditional compact 2x system. A tight 13-tooth gap between the inner and outer rings keeps front shifts accurate and chain drop to a minimum.

Highlights

• 107BCD asymmetric bolt circle — fits SRAM Rival AXS cranksets
• X-Range gearing — smaller chainrings paired with 10-tooth cassette start for full gear coverage
• Tight 13-tooth gap between inner and outer rings for accurate, dependable front shifts
• X-SYNC tooth profiling for secure chain engagement
• Available in multiple tooth count combinations

X-Range: smaller rings, same range

X-Range shifts the chainring sizes smaller and compensates by starting the cassette at 10 teeth rather than 11. The result is the same overall gear range with physically smaller, lighter chainrings that also improve ground clearance and reduce rotational mass. The 13-tooth gap between rings is designed to keep front shifts crisp and predictable.

Fit and compatibility

107BCD asymmetric bolt circle — fits SRAM Rival AXS road cranksets. Confirm tooth count combination and inner/outer ring requirement before ordering. Compatible with SRAM AXS 12-speed chains.
