Other Versions to Consider

Shimano GRX RX810 2x Crankset: If you are looking for a 2x crankset to provide a bit more range in your drivetrain, check out the Shimano GRX RX810 2x Crankset. A 1x can offer the convenience and weight savings of eliminating a front derailleur, but a 2x crankset can provide extra range for rolling or steep terrain.
