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.

Shimano’s GRX RX825 Di2 front derailleur delivers quick and precise front shifting even under heavy loads. Designed for a wider, 17T gear range, it utilizes a +2.5mm chainline for improved tyre clearance. The FD-RX825 is compatible with Full, Semi-Synchronized shift modes as well as the new Front Shift Next function for greater rider customization.

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.
