Shimano GRX BL-RX825 Hydraulic Brake Lever

The Shimano GRX BL-RX825 is a left-only hydraulic brake lever designed to pair perfectly with the right-hand GRX ST-RX825 Di2 dual-control lever. Matching shape, ergonomics and reach adjust make this an ideal option for 1x gravel setups where you want the premium GRX Di2 right-hand shifter but don't need shifting on the left.

The GRX RX825 series is Shimano's 12-speed wireless Di2 gravel groupset. It features a fully wireless STI design with a 3-4 year coin-cell battery life, rounded hoods shaped for flared drop bars, three Di2 buttons per lever with full E-TUBE customisation (including FRONT SHIFT NEXT), and SHADOW RD+ chain stabilisation.

• Left-side hydraulic brake lever, no shift function
  
• Shape and ergonomics match the ST-RX825 Di2 right-hand lever
  
• Ideal for 1x12-speed Di2 gravel setups
