Front brake caliper Shimano Hydraulic BR-RX400 Flat Mount

The GRX brake calipers have a design reminiscent of the SHIMANO Flat Mount models of the road bike industry and offer equally high braking performance. They also have established features such as One-Way Bleeding and ICE-TECHNOLOGIES heat management system with pads and brake discs with aletta for maximum fading resistance.

SHIMANO's GRX, the first family of gravel-specific components designed both for fast progress and for safe handling of bicycles on loose surfaces, is the result of an intense and extensive research, testing and development process that incorporates information and feedback from countless pilots on trails, forest tracks, gravel and asphalt tracks around the world.
