You asked. We listened. Introducing the long-awaited Round Chainrings for Shimano® GRX® cranksets using the 110 BCD outer and 80 BCD inner 4-bolt configuration. Designed specifically for compatibility with Shimano FC-RX810-2 cranks for an easy chainring upgrade. See the chart below for tech specs.
Compatible with Shimano® GRX® crankset (FC-RX810-2), Shimano® GRX® 11sp groupset, and either Shimano® 11-speed chain or KMC 11-speed chain.
•Our 2x rings for GRX do not include chainring bolts. They are designed to use the stock Shimano bolt set.
