Shimano GRX RX810 1x11 40 Groupset

The Shimano GRX RX810 1x11 groupset - made for adventurers

The Shimano GRX RX810 1x11 groupset is the result of two years of close collaboration with Gravel enthusiasts from around the world. It consists of a 1x crank with a 40 tooth chainring, +rear derailleur, disc brake with STI right and left shift levers, chain and cassette (Ultegra or MTB). 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.
