Product information "GRX ST-RX400+BR-RX400 2-speed Disc Brake front"

A central concern of Gravel riders is a reliable braking system with sufficient power reserves, the Shimano GRX 2-speed ST-RX400 STI with BR-RX400 Flat-Mount caliper for hydraulic disc brake is characterized by excellent deceleration performance to maintain control on steep, demanding or even surprising descents (no box packaging).

For gravel, road and cyclocross use: Shimano 2-speed STI Dual Control ST-RX400 + BR-RX400 Disc Brake front

All STI Dual Controler feature an 18mm higher brake lever pivot axis, a curved lever shape and non-slip textures on the contact surfaces for optimum grip even in the roughest terrain.

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.
