ALUGEAR 1x 110×4 Chainring for Shimano 12-Speed

The ALUGEAR 1x 110×4 Chainring for Shimano 12-Speed is compatible with R7100/R8100/R9200 cranksets and is designed for both road and gravel riding. This chainring is made using an updated construction that adds strength and stiffness while maintaining a light weight. ALUGEAR chainrings use a unique tooth profile that eliminates chain noise, reduces wear and provides a more efficient drivetrain. It is CNC machined from 7075-T6 aluminum and are anodized to provide protection from mechanical impacts.

You can also pair this chainring with an ALUGEAR Aero Cover. This eliminates any gaps between the crank arm and the chainring, providing additional aero benefits. Each aero cover (7100, 8100 or 9200) is designed to match the finish of the crank arm.
