Stone 110BCD 5-Bolt Round Chainring, 4mm Offset for 1x Chainline, 42T–60T, Narrow-Wide for SRAM Red/Force/Rival, Quarq & 110BCD 5-Arm Cranks
The Stone 110BCD 5-bolt round chainring is designed for 1x road, cyclocross, and gravel drivetrains. Its 4mm inward offset helps correct the chainline when converting a bike from a 2x setup to a 1x setup, allowing the chain to run straighter and the drivetrain to work more efficiently.
The narrow-wide tooth profile improves chain retention and helps reduce chain drop, making it a dependable choice for single-chainring riding.

Shimano 12-Speed Chain Notice
When using a Shimano road 12-speed chain, replace the original Shimano 12-speed quick link with another compatible 12-speed quick link, such as KMC, YBN, or SUMC.
The original Shimano 12-speed quick link may be too narrow and can cause chain engagement issues.
