Shimano GRX RX810 Chainring 2x
Shimano GRX RX810 Chainring 2x Info
The Shimano GRX RX810 Chainring 2x is a direct-replacement chainring for GRX 800-series double cranksets, engineered to maintain the front-shift performance and chain retention that GRX's gravel-specific drivetrain geometry is built around. Available in 31t and 48t, these rings cover both inner and outer positions of a 2x setup — so you can replace worn rings or reconfigure your gearing without changing the crankset.
The 31t inner ring is suited to loaded bikepacking routes and technical terrain where climbing gearing matters most. The 48t outer ring fits riders mixing tarmac with hardpack and gravel, where a larger ratio keeps you spinning efficiently on the flatter sections. Because both are designed specifically for the RX810 2x crankset, shift timing and chain pickup hold up the way they should on broken ground — where a road-oriented chainring would start to show its limits.
