Shimano GRX ST-RX825/BR-RX820 Shifter/Hydraulic Brake Lever Set

The Shimano GRX ST-RX825/BR-RX820 Shifter/Hydraulic Brake Lever Set pairs wireless 12-speed Di2 shifting with hydraulic disc braking in a single J-Kit package built around the demands of gravel riding. The ST-RX825 lever is designed specifically for flared drop bars — the raised hood profile, smoother hood-to-bar transition, and textured anti-slip surface give you a more secure grip when conditions turn rough and your hands are working to stay in place.

On the shifting side, the completely cable-free cockpit runs on long-lasting coin cell batteries and supports satellite shifter compatibility, including a new third button position suited to gravel-specific hand positions. Front Shift Next and synchronized shifting let you dial in how the drivetrain responds to your inputs across varied terrain. Paired with the BR-RX820 hydraulic caliper — which features ten percent more pad clearance to reduce brake rub and a simplified bleeding process — the system is built to stay consistent and easy to maintain through long days in the dirt.
