Shimano GRX - Explore Beyond

Instead of telling gravel riders what they needed, Shimano asked them what they wanted for their offroad adventures. The result are the Shimano GRX components which represent the first series especially developed for riding on rough roads and through gravel. The Shimano GRX sets itself apart from the rest of the component world with its gravel specific ergonomics, optimized gearing options, rugged reliability as well as a quiet and stable drivetrain.

Shimano GRX brake set consisting of the BL-RX600-L brake lever for safe control and the hydraulic BR-RX400 caliper for solid braking performance.

Shimano GRX BL-RX600-L disc brake lever

The Shimano GRX BL-RX600-L provides Gravel inspired ergonomics both for the bracket design to accommodate every kind of drop bar and for the lever itself featuring an anti-slip coating for greater mixed-terrain control. In order to meet the individual needs of the driver, the hydraulic brake lever offers a tool-based reach adjustment as well.

Shimano GRX BR-RX400 disc brake caliper

Never hesitate to tackle rough surfaces with the hydraulic Shimano GRX BR-RX400 caliper. In doing so Ice Tech ensure excellent heat dissipation while the BR-RX400's 2 pistons guarantee solid braking performance under all conditions. The Flat Mount system makes it possible to attach the disc brake caliper directly at frame or fork. Trouble-free and simple maintenance is provided by the proven One Way Bleeding concept and the Easy Hose Joint System which simplifies brake hose exchanges.

Ice Technologies

The fading which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice-Tech disc brake rotor and brake pad to realize the cooling technology for consistent performance. The disc brake rotor blade which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving a lower surface temperature. Aluminium cooling fins have been adopted the brake pad improving the radiation performance even further. In combination the disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.

J-Kit (Easy Hose Joint System)

At brake systems with J-Kit hose joint the brake lever features an integrated olive what makes an easy brake hose installation and removal possible.
