What is the SRAM X-Sync 46T 4-Bolt Chainring?

The SRAM X-Sync 46T Chainring is a 4-bolt, 107mm BCD replacement ring for SRAM road cranksets using the 107mm spider interface. X-Sync narrow-wide tooth profile alternates between wide and narrow teeth to engage inner and outer chain links, providing outstanding chain retention without a chain guide in a 1x setup. The 46T size suits a wide range of road and gravel gearing configurations. Compatible with 12-speed AXS Flattop chains.

Confirm your crankset uses a 107mm BCD 4-bolt spider interface before ordering. This is the correct chainring for SRAM road cranksets with that specific spider, not for direct-mount or Thread Mount cranksets.

FAQ

What cranks use a 107mm 4-bolt BCD?

The 107mm 4-bolt interface is used on SRAM's road AXS cranksets including Force AXS, Rival AXS, and compatible Quarq power meter spindles. Confirm your crankset's BCD before ordering.

What is X-Sync?

X-Sync is SRAM's narrow-wide tooth profile for 1x drivetrains. Alternating narrow and wide teeth match the chain's inner and outer links for superior chain retention without a chain guide, particularly useful on rough terrain.

Is this compatible with SRAM Flattop chains?

Yes. The X-Sync 46T 12-speed chainring is designed for use with SRAM's Flattop 12-speed chain used in the road AXS ecosystem.

Best For

Road and gravel riders running SRAM 12-speed AXS 1x drivetrains on cranks with a 107mm 4-bolt spider who need a replacement or upgraded chainring.
