Shimano GRX ST-RX815 11-Speed Di2 Right Drop-Bar Shifter/Hydraulic Brake Lever without hose or caliper

The Shimano GRX ST-RX815 Shifter/Hydraulic Brake Lever delivers comfort and control so you can ride assured and without agitation. The raised hood head optimizes hand alignment, and the anti-slip coating prevents slippage. Braking efficiency is provided by a higher brake lever axis and curved shape, and this also decreases the chance of fatigue when you're spending long days in the saddle.
