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 Shimano GRX Dual Control Lever delivers light and responsive mechanical 12-speed shifting for mixed-terrain riding and racing. The ergonomic shifter design improves comfort by decreasing pressure on your palms, while the textured, anti-slip brake lever surface increases control on bumpy terrain.
Technology
Dual Control Lever
DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation.
Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from our MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration, and simply has to be experienced to be understood.
The Dura-Ace / Ultegra / 105 Dual Control Lever have an optimized structure with features that include the lighter weight pivot section in the near side of the shifting unit and the integral shifting cable for lighter steering. Its many component parts are made so compact and precise to achieve unprecedented high-speed performance.
Servowave Action
When you pull a Servowave 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.
Reach Adjust
Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.
Features
- GRX hydraulic disc brake STI's give you control, modulation and power with minimal effort in all riding conditions
- Raised hood head prevents hand misalignment and slippage
- Anti-slip texture and brake lever coating gives higher braking efficiency and reduces fatigue on long rides
