Shimano GRX BR-RX400 + ST-RX600 disc brake set - makes off-road riding safer

With the Shimano GRX BR-RX400 + ST-RX600 disc brake you don't have to shy away from rough surfaces. The GRX BR-RX400 brake calipers follow the flat-mount design that has proven itself in recent years as the standard for Road disc brakes because of its user-friendliness. They convince through excellent heat management and simple setup. The GRX ST-RX600 Dual Control Technology shift/brake lever has an anti-slip surface and its shape has been adapted to the ergonomic requirements of Gravel riding. The smooth shift function has been taken from the Shimano top-lever groupsets. So don't hesitate to use the BR-RX400 + ST-RX600 brake for your next off-road ride.

STI Dual Control (DCL)
DCL stands for Dual Control Lever. It has braking and shift functions and allows easy operation. The improved ergonomics is probably even more important for the high standard than more range. The shift levers bring the stability of Shimano MTB technology and work so precisely and smoothly that it is possible to shift gears both front and rear with just one finger. This is a highlight of Shimano's " Total Integration" (STI). To believe it, you just have to experience it for yourself.

Optislick cables feature a minimal and uniform electrically coated layer that improves cable routing efficiency and provides excellent corrosion resistance.

One-Way Bleeding is designed to quickly and easily prevent air from entering the hydraulic system. Shimano has optimised the brake fluid flow path throughout the system to prevent air bubbles from being trapped in the system.
One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.

Fading of the brake during prolonged uninterrupted operation, e.g. downhill, impairs braking performance. Shimano has introduced brake rotors and pads with Ice-Tech technology to create a cooling technology for consistently high braking performance. The brake rotor has a three-layer stainless steel sandwich structure on the outside around an aluminium core. It radiates heat better and reduces surface temperature from 400° C to 300° C, for example. The brake pads also have optional cooling fins. The design of the rotor in combination with the cooling fins results in a longer service life of the pads, less braking noise, less fading and lower weight.
