Shimano GRX Di2 RX815 Disc 2X11-speed 3-port electric gravel groupset

Specially designed for gravel, the Shimano GRX 2x11-speed Di2 drivetrain provides a reliable and high-performance solution for intensive use in extreme conditions. Inspired by the Japanese brand's high-end road and mountain bike groupsets, it features flagship technologies such as the Shimano Shadow RD+ rear derailleur system, which ensures optimal chain tension to maintain precise and smooth shifting even on rough terrain, while preventing derailment. Disc brakes are standard for this group, with a hydraulic system that provides remarkable power and progressive braking, thanks in particular to the ergonomic levers. The crankset is available in 48-31 teeth, allowing you to tackle even the most technical challenges with enough torque to get over the bike. Di2 derailleurs guarantee impeccable precision and ease of use that you won't be able to do without, as they can be operated with a light touch on the controls without having to make any big movements.
