SHIMANO GRX RX810 1X11 42 GROUPSET

The Shimano GRX RX810 1×11 groupset – made for explorers

The Shimano GRX RX810 1×11 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 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.
