Any of these gearing combinations pairs with Shimano’s latest carbon gravel wheels, the WH-RX880. With 25-millimeter internal width and updated DIRECT ENGAGEMENT freehub, the RX880 wheels provide a vital connection between rider and road, however remote or rugged.
Unrivaled Shimano Di2 Electronic Shifting for Gravel
Like its 12-speed DURA-ACE, ULTEGRA, and SHIMANO 105 Di2 siblings, the new GRX Di2 system is wired where it makes sense, featuring a central, multi-port battery that supplies stable, long-lasting power to both front and rear derailleurs. Smaller diameter wires connect directly from the battery to each derailleur, eliminating the need for junctions and streamlining the build process. The central internal battery also simplifies charging and remains secure over the roughest roads, trails, or whatever less traveled path a rider may choose.
