Description
The ALUGEAR AERO GRX 12-speed outer chainring is designed for 2x11- and 2x12-speed gravel drivetrains. It fits as the large chainring on Shimano GRX FC-RX820-2 and FC-RX810-2 cranksets with an asymmetric 4-arm 110 BCD bolt pattern, and comes in 46- or 48-tooth versions.
Made from 7075-T6 aluminium using CNC machining, it weighs approximately 110 g with 46 teeth and 123 g with 48 teeth. Industrial hard anodising increases protection against mechanical impacts and helps preserve its black finish over time.
Its AERO design follows the profile of the GRX crank arm for visual and aerodynamic continuity. ALUGEAR chainrings are tuned to deliver their best shifting performance in the combinations specified by the manufacturer.
Compatible with Shimano HG+ 12-speed, Shimano 11-speed and KMC 12-speed chains. Sold individually, without fixing bolts.
