Shimano GRX BL-RX825 Hydraulic Drop Bar Brake Lever

Shimano GRX, with its gravel specific ergonomics, optimised gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world.

The GRX brake lever (For Di2) is a left-only brake lever option that pairs perfectly with a right ST-RX825 dual control lever. It is designed for gravel and mixed-terrain riding. The ergonomic lever features raised hoods, ribbed surface texture, and an anti-slip coating on the brake lever for increased security and control. The hood body is optimised for seamless integration with flared handlebars.

Raised Hood Head

Raised hood head prevents hand misalignment and slippage.

Secure Grip for Rugged Terrain

The textured surface of the GRX hood ensures you're always in control, even on bumpy descents.

Never Miss A Braking Point

The anti-slip coating on GRX brake levers means that even in wet or muddy conditions that you'll always have Shimano's legendary stopping power on demand.

Hood Shape Optimised for Flared Handlebars

With a rounded profile, the new GRX RX820 hood shape distributes pressure over more of your hand, ensuring long-range comfort.

Technology

Servo Wave Action

When you pull a Servo Wave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.
