Shimano GRX FC-RX810-2 Crankset

The GRX FC-RX810-2 is specifically designed for gravel drivetrains and features a wider chainline optimized for 135/142mm road disc hubs. While it uses the standard Hollowtech II interface, you should verify that your frame's chainstay clearance and front derailleur are compatible with the GRX-specific chainline before installing.

No, the bottom bracket is not included with this crankset. You will need to purchase a compatible Shimano Hollowtech II bottom bracket separately based on your frame's specific shell standard, such as BSA threaded or PressFit.

This model features a 48/31 tooth chainring combination. This sub-compact gearing is specifically engineered for gravel, offering a lower gear range that makes steep, loose, or technical climbs significantly more manageable compared to standard road gearing.

The FC-RX810-2 is optimized for Shimano's 11-speed gravel drivetrains. While it may physically fit other setups, it is designed to provide precise shifting performance specifically within the 11-speed ecosystem, so we recommend sticking to that configuration for the best results.

The 110mm asymmetric BCD is a proprietary Shimano design that places the chainring bolts in specific positions to optimize stiffness and weight. When it comes time to replace your rings, you will need to source specific Shimano GRX-compatible rings rather than standard aftermarket 110mm BCD options.
