The Shimano GRX Di2 1x11 Custom Groupset is the first truly gravel-specific groupset, calling upon Shimano’s decades of experience making some of the best bike components on earth. The GRX Di2 series uses Di2 electronic shifting technology to make shifting faster, more precise, and more customizable than ever before, with Shadow Plus rear derailleur design and a clutch mechanism for improved off-road performance. The 1x11 design simplifies finding the ideal gear, by eliminating the need for a front derailleur, ideal for technical off-pavement riding. This complete groupset includes the majority of components you need to build up the gravel bike of your dreams—or make some major upgrades to your existing gravel rig.
