Product Description
The Shimano GRX ST-RX815 left Di2 shift/brake lever with BR-RX810 caliper is built for gravel and mixed-surface riding where control, comfort, and confident braking matter most. This setup combines 11-speed Di2 electronic shifting with a hydraulic flat mount disc brake, giving riders crisp front shifting and strong brake performance in rougher conditions.
The GRX hood and lever shape are designed specifically for off-road drop-bar use, with a raised hood head, recessed finger notch, and anti-slip texture to improve grip and hand security on choppy terrain and descents. This version comes pre-bled with a 1000mm hose and uses resin pads.
