Description

The SHIMANO GRX ST-RX400 + BR-RX400 Right Lever and Rear Caliper combines shifting and hydraulic braking in a single Dual Control unit, designed for 10-speed GRX groupsets. Its gravel-inspired ergonomics, curved hood and non-slip finish provide improved control on changing terrain, with shifting performance worthy of high-end road groupsets.

The BR-RX400 Flat Mount caliper delivers consistent braking power thanks to its 2 resin pistons and Ice Tech pads, which optimise heat dissipation. The brake lever pivot, raised by 18 mm, further improves braking performance.

The One Way Bleeding system and Easy Hose Joint connection make maintenance simple, for a reliable set ready to tackle gravel, cyclocross and adventure riding.
