Shimano GRX Hydraulic Disc Brake/Shift Set, ST-RX600/BR-RX400, For 2x11-Speed (Left/Front)

A central concern of Gravel riders is a reliable braking system with sufficient power reserves, the Shimano GRX 2 x 11-speed ST-RX600 STI with BR-RX400 Flat-Mount caliper for hydraulic disc brake is characterized by excellent deceleration performance to maintain control on steep, demanding or even surprising descents.

Shimano GRX ST-RX600 shift/brake lever

The Shimano GRX ST-RX600 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 2x11-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.
