Shimano GRX RX400 - 2x10 gravel derailleur

The new Shimano GRX group dedicated to gravel bikes makes riding both asphalt and off-road a pleasure. It is not a road or mountain group with a "new sticker". This equipment has been designed from scratch with the use of refined technologies. With the Shimano GRX RX400 you will discover completely new paths. Have you always wondered where this road in the forest leads, which you have always driven along the road? Take it and see for yourself! The SHIMANO GRX RX400 has an integrated chain stabilizer (RD +) mechanism that tightens the chain so it does not jump over bumps. This reduces the risk of the chain falling off and translates into more precise shifting. Stabilization can be turned off with a switch located on the shifting carriage.

Shimano GRX RX400 - hydraulic gravel brake
SHIMANO GRX RX400 hydraulic disc brakes are a low-profile, flat-mount model that is the twin brother of road bike brakes. It has been tested by many cyclists. So it is a proven brake with high braking power, which is very necessary when driving off-road. After all, gravel was created for this! So, it's good to have gravel brakes that can handle whatever challenges you may face. Since the GRX RX400 is a hydraulic brake, changing the wheel or inner tube is extremely simple and does not require the subsequent setting of the brake pads as is the case with the use of rim brakes. The brakes work with the K03S, L03A and metallic K04S blocks.
