Discover the Shimano GRX Di2 Shift Lever Kit + ST-RX825(R) Rear Brake + BR-RX820(R) at Escapa , featuring dual-control shift levers designed to optimize comfort and control while delivering the powerful braking performance of the BR-RX820 brake calipers.
Wireless Cockpit designed specifically for Gravel
At the front of the bike, the 12-speed GRX Di2 features a wireless Gravel-specific Cockpit, with ribbed rubber grips and non-slip brake levers that ensure excellent hand grip, no matter how intense your ride gets. Grip is further enhanced by the placement of the third Di2 button on the inside of the grip, just as with the original GRX RX815 Di2 shift levers. This third button is yet another way to get the most out of your Shimano Di2 electronic system—you can use it as an additional shift position or to navigate your GPS screen so you don’t miss the next turn on your ride.
The new Di2 system also supports additional shift buttons—yet another advantage of electronic shifting. By connecting any of Shimano’s satellite buttons—whether on the topstops, standard handlebars, or aero handlebars—the rider can maintain a more consistent effort without having to move their hands. Just as with the third button on the GRX Di2 dual-control shifters, you can assign these satellite buttons to various functions—whether for shifting either derailleur, controlling compatible lights and GPS devices, or timing your workouts.
The new dual-control shifters also feature a Gravel-optimized cross-section, allowing for seamless integration with widened handlebars. With a rounder shape, the transition from the handlebars to the shifters’ rubber grips is smoother and creates a larger contact surface, which helps eliminate pressure points. All so you can ride more comfortably and extend your ride a little longer.
E-TUBE PROJECT Customization
With Shimano’s E-TUBE PROJECT Cyclist app, riders can choose from different shifting speeds, customize the functions of the shift buttons, program various shifting modes such as synchronized and semi-synchronized shifting, fine-tune shifting, or connect to external bike computers.
The launch of the RX825 coincides with the rollout of Shimano’s new FRONT SHIFT NEXT feature. This firmware update allows you to use the simple Cyclist app to program any of the RX825 Di2’s buttons to shift the chain to any chainring you’re not currently using. In addition, you can assign the FRONT SHIFT NEXT function to any of the three shift buttons on the RX825 dual-control shifters. This will allow less experienced cyclists to shift more easily and intuitively, and veterans to make decisions faster in the heat of competition.
But in addition to greatly simplifying the shifting process, Shimano’s FRONT SHIFT NEXT function can free up other buttons and assign them to different functions—whether to navigate through the screens of a GPS, turn lights on and off, or use the bike computer’s stopwatch function—so you don’t have to take your hands off the handlebars, even during the most intense moments of effort.
