Shimano GRX Di2 RX815 1x11 groupset - departure into the unknown


The Shimano GRX Di2 RX815 1x11 electronic 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, Di2 rear derailleur, disc brake with STI Di2 right and left shift levers (programmable to 1x = without shift function), 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 electronic component groupset, the GRX Di2 by Shimano.
