Shimano GRX Di2 ST-RX825 hydraulic control lever + BR-RX820 12V

The SHIMANO GRX Di2 12-speed Dual Control Lever ensures fast, wireless shifting for gravel riding and mixed terrain.

The ergonomic lever features raised hoods, a sculpted surface, and a non-slip coating on the brake lever to provide greater safety and control. The hood body has been optimized for perfect integration with flared handlebars and retains the third-button position specific to gravel riding. Completing the cockpit, the RX825 levers are compatible with three satellite shifter options and offer the SHIMANO Front Shift Next function, maximizing customization possibilities.
The GRX BR-RX820 disc brake caliper delivers new levels of control for road cycling, with improved modulation and a more immediate brake engagement point. Despite its more compact design, the system is quieter than ever and easier to maintain.
