Shimano GRX - Explore Beyond

Instead of telling gravel riders what they needed, Shimano asked them what they wanted for their offroad adventures. The result are the Shimano GRX components which represent the first series especially developed for riding on rough roads and through gravel. The Shimano GRX sets itself apart from the rest of the component world with its gravel specific ergonomics, optimized gearing options, rugged reliability as well as a quiet and stable drivetrain.


Shimano GRX ST-R4600 shift/brake lever

The Shimano GRX ST-RX400 dual control lever provides Gravel inspired ergonomics both for the bracket design to accommodate every kind of drop bar and for the lever itself featuring a curved shape and an anti-slip coating for greater mixed-terrain control. In terms of shifting performance the 2x10-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.
