Shimano GRX RX810 groupset 1x11 40

The Shimano GRX RX810 1x11 complete 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 crankset with a 40-tooth chainring, rear derailleur, disc brakes with a right-hand STI shift/brake lever, chain, and cassette (Ultegra or MTB). Rather than telling gravel specialists what they should ride, Shimano asked them what they wanted to ride. That meant exploring countless unpaved trails, racing cyclocross, going on bikepacking trips, eating plenty of dust, and getting covered in mud. The result is the world's first gravel-specific component group: Shimano's GRX.
