Electrifying Shimano’s 12-speed gravel component family, the new 2 x 12-speed GRX RX825 Di2 components combine Shimano’s unrivalled electronic shifting with optimized gearing options for riding, racing, and all-day adventures. 

Designed for gravel riders who live to be in the moment, who venture down lonely, unknown dirt roads, who take on routes and races with unpredictable outcomes, Shimano GRX 12-speed Di2 delivers precise, reliable, distraction-free performance in all conditions.

The 12-Speed Shimano GRX Di2 Dual Control Lever delivers fast, wireless shifting for gravel and mixed-terrain riding. The ergonomic lever features raised hoods, ribbed surface texture, and an anti-slip coating on the brake lever blade for increased security and control. Optimized for use with flared handlebars the lever delivers a wireless cockpit that is compatible with three satellite shifter options and features Shimano Front Shift Next functionality to maximize rider customization options.

The new Shimano Front Shift Next functionality is a firmware update which allows users to program any 12-speed Di2 shift button to shift the front derailleur to which ever chainring you are not currently using and then toggle back and forth using the same button. The result is simpler, more intuitive shifting for less-experienced riders and quicker decision-making for veteran riders in the heat of competition. Along with dramatically simplifying the gear-changing process, Shimano Front Shift Next can also free up other switches to handle tasks such as moving through multiple screens on a paired cycle computer, turning on and off compatible lights, or hitting the “lap” button on your cycle computer so you can keep your hands securely in place, even during your hardest efforts.
