Features
The Shimano BL/ST-RX810+BR-RX810 1x11-speed disc brake kit is designed to meet the specific needs of gravel riders but also performs excellently on the road. It consists of Shimano GRX 1x11 BL/ST-RX600 levers and BR-RX400 Flat-Mount calipers for hydraulic disc brakes. These components provide excellent stopping power, essential for maintaining control on steep and demanding descents.
The kit also features a taller 18mm brake lever pivot axle, a curved lever shape, and anti-slip textures on the contact surfaces for optimal grip. It is complemented by the RX800 and RX600 STI 1x11-way for the left without shifting or DSP functionality, including the 1x11 Di2 version (ST-RX815).
The GRX brake calipers have a design reminiscent of SHIMANO Flat Mount models from the road bike sector and offer equally high braking performance. They also feature well-established features such as One-Way Bleeding and the ICE-TECHNOLOGIES heat management system with finned brake pads and rotors for maximum resistance to fade.
