Shimano GRX - Explore Beyond
Instead of telling gravel bikers what they should use on their tours, Shimano thought about what cyclists need for their off-road adventures. The result is the Shimano GRX components, which together form the first group that was specifically developed for use on rough routes and gravel. The Shimano GRX sets itself apart from the rest of the component world with its gravel-specific ergonomics, optimized gradation options, proven robustness and a quiet and stable drive.

Shimano GRX ST-RX600 shift/brake lever
The hydraulic Shimano GRX ST-RX600 shift/brake lever offers ergonomics tailored to gravel use, both in the area of ​​the bracket, which allows it to be mounted on any type of handlebar, and in the handle itself, which has a curved shape and with has an anti-slip coating, which ensures more control in constantly changing terrain. When it comes to shifting performance, the 2x11-speed GRX STI levers are in no way inferior to the high-quality Shimano road bike shifters. The rotation axis of the brake lever is 18 mm higher to improve braking performance. In order to meet the individual needs of the driver, the reach of the brake handle can be adjusted using a tool.

Shimano GRX BR-RX400 disc brake caliper
With the hydraulic Shimano GRX BR-RX400 brake caliper, even the toughest terrain can be attacked without hesitation. Take care of it
Ice Tech brake pads for excellent heat dissipation and in conjunction with the 2 pistons of the BR-RX400 for stable braking performance in all conditions. The disc brake caliper is attached directly to the frame or fork using a flat mount. The proven One Way Bleeding system and the Easy Hose Joint System, which make replacing brake lines significantly easier, ensure smooth and easy maintenance.

Ice Technologies
Brake fading impairs braking performance when used continuously for a long period of time. Shimano has introduced Ice-Tech brake discs and pads to create cooling technology for consistently high braking performance. The brake disc has a three-layer sandwich structure made of stainless steel on the outside around an aluminum core. It radiates heat better and reduces the surface temperature. The brake pads have aluminum cooling fins, which further optimize the radiation properties. The design of the disc in conjunction with the cooling fins results in longer durability of the pad, less braking noise, less fading and also reduces weight.
