Description

The SHIMANO GRX ST-RX610 Left-Hand Lever + BR-RX400 Flat Mount Front Calliper combines a mechanical 2x12-speed dual-control lever and a 2-piston hydraulic brake calliper in a ready-to-fit kit. Designed for gravel riding, it delivers light, responsive shifting and powerful, controllable braking on mixed terrain.

The lever body, with ergonomics tailored to gravel riding, has a textured hood and an anti-slip coating on the brake lever for better control on bumpy or muddy surfaces. Reach Adjust lets you tailor the lever to any hand size.

The BR-RX400 Flat Mount calliper uses SHIMANO ICE TECHNOLOGIES for excellent heat dissipation, with L05A-RF resin pads featuring finned backing plates. One Way bleeding simplifies maintenance, while the J-Kit connector makes installation, maintenance and wheel changes easier.

Designed for left-hand lever and front calliper installation, this kit is compatible with 2x12-speed GRX drivetrains; the brake disc is sold separately.
