Shimano GRX 815 Di2 2x11-Speed Gravel Groupset
A big advantage of GRX is that it is not just a single groupset but rather a family of components that can be purchased in pick ’n’ mix fashion to take on different guises across various price points. GRX can be configured as 1x or 2x, so take your pick as to whether you go for the road or MTB influence, but either way there are sufficient options to ensure no one should be left wanting when it comes to setup options.
Electrifying Shimano's 11-speed gravel component family, the 2x11-speed GRX RX815 Di2 components combine Shimano's unrivalled electronic shifting with optimized gearing options for riding, racing, and all-day adventures.
Included in the groupset are six SD300 E-Wires, use the What's in The Box tab to view the wire length included. If you require different lengths please add a note within your order.
Shimano GRX RX815 11-speed is a wired electronic groupset based upon Shimano’s 11-speed electronic road bike groupsets, with wired shifters and wired front and rear derailleurs. It is pitched at roughly the same level as Shimano’s Ultegra Di2 R8100 and Deore XT M8100 components and is only available as a double or 2x12 groupset.
The groupset does not include rotors.
The groupset does not include Shimano BCR2 charger.
