Shimano GRX RX810 1x11 Groupset

The Shimano GRX RX810 1x11 groupset results from a two-year close collaboration with Gravel enthusiasts from around the world. It includes a 1x crank with a 42 tooth chainring, rear derailleur, disc brake with 11-speed STI right lever and left brake lever, chain and cassette.

Shimano didn't want to tell the Gravel specialists what to ride, but asked them what they wanted instead. Many unpaved paths were explored, off-road races contested, bikepacking tours undertaken, a lot of dust swallowed and mud bath galore. The result is the world's first Gravel-specific component groupset, the GRX by Shimano.

Additional components needed:

- The bottom bracket is not included. Shimano recommends BBR60 or BB72 Pressfit.
- Rotors are not included and will be specific to your bike & wheel spec. Shimano recommends RT-MT800 (140, 160 or 180 mm).
- An additional 1.85 mm spacer is required if the cassette is to be mounted on a road freehub.
- Brake adapters may be required. Front is supplied with adapter for 140/160mm rotor spec
