The hydraulic 2-piston brake caliper Shimano GRX BR-RX400 for rear with Flat-Mount and L03A Resin disc pads with fin.
For gravel, road and cyclocross use: Shimano GRX BR-RX810 Flat-Mount Brake Caliper
The GRX brake calipers have a design reminiscent of the SHIMANO Flat Mount models from the road bike sector and deliver equally high braking performance. They also have established features such as One-Way Bleeding and the ICE-TECHNOLOGIES heat management system with brake pads and brake discs with fin for maximum fading resistance.
SHIMANO’s GRX, the first Gravel-specific component family designed for both fast progress and safe bike handling on loose surfaces, is the result of an intensive and extensive research, testing and development process that incorporates information and feedback from countless riders on trails, forest tracks, gravel tracks and asphalt all over the world.
