Shimano GRX ST-RX825 Di2 Shift-Brake Levers with Calipers. Flat Mount

The Shimano GRX ST-RX825 Di2 Shift-Brake Levers with Calipers for flat mount disc brakes deliver fast and reliable wireless shifting to your gravel bike. Shimano has updated these brake levers to be rounder and they now use a textured brake hood. This helps you easily grip the levers, even in the worst conditions. They have also been redesigned to match the profile of flared drop handlebars which makes it easier to shift and brake in the drops. These levers are also now fully wireless so installation is a breeze.

In addition, Shimano has added an auxiliary button on the inside of the right shifter. In the E-TUBE app you can customize your shift logic and assign any of the shift buttons to Shimano’s new FRONT SHIFT NEXT function. A single press of this button means the front derailleur will shift, making it easier to change gears on any terrain. Additionally, the Shimano GRX ST-RX825 Di2 Shift-Brake Levers are compatible with three additional Shimano satellite shifters. With Contact Point Adjustment and Reach Adjust you can also adjust your reach exactly to your liking.
