Shimano GRX FC-RX810-2 Chainring

Shimano inner / outer chainring for the named series crankset — the replacement tooth ring you swap when the teeth are worn down to the point where shifting gets rough or the chain starts slipping under load. Sold as the specific tooth-count variant matching your crankset configuration; not a complete crankset. GRX is Shimano's gravel / adventure groupset — clutch-equipped derailleurs, wider-range gearing, ergonomics tuned for on / off-road riding and hood-level grip on rough surfaces. This is the Shimano GRX FC-RX810-2 Chainring.
