Shimano ST-RX600 GRX Mechanical 2×11 Speed STI Levers

In terms of shifting performance the 2×11-speed GRX STI levers are at the same high level like Shimano's top tier group's road bike shifters

In contrast the braking performance is optimized by the brake lever's rotary axle which is positioned 18 mm higher than usual

In order to meet the individual needs of the driver, the hydraulic brake lever offers a tool-based reach adjustment as well.

Raised hood head prevents hand misalignment and slippage
