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.

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.
