ALUGEAR Oval 1x 110×4 Chainring for Shimano 12-Speed
The ALUGEAR Oval 1x 110×4 Chainring for Shimano 12-Speed is an oval chainring that is compatible with R7100/R8100/R9200 cranksets. It is made for 1x drivetrains and road, gravel and CX riding. This chainring is made using an updated construction that adds strength and stiffness while also being lightweight. ALUGEAR chainrings use a unique tooth profile that eliminates chain noise, reduces wear and provides a more efficient drivetrain. The oval shape also helps reduce strain on your knees and back and improves the smoothness of your pedal stroke. It is CNC machined from 7075-T6 aluminum and 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.
