Description

SHIMANO GRX Disc Brake Set Shift | Brake lever ST-RX820 + BR-RX820 Flat Mount left

With the GRX, Shimano brought the first gravel-specific shifting group onto the market. Since then, the range of uses and the range of gravel bikes has expanded significantly. Shimano takes this development into account by also expanding the range of the GRX group. With 12 sprockets on the rear wheel and the option to choose between a 1-speed and 2-speed setup, you can adapt your drive even better to your needs.

The GRX shift-brake levers have a grip geometry and surface texture specially optimized for Gravel use. The upper hump has been raised so that you cannot slip forward on rough ground. A thumb cut-out ensures a firm grip in difficult terrain at all times. And so that your hands don't slide back and forth when driving in the rain, a non-slip material was chosen, which also has good damping properties and thus increases comfort.
As usual, the dual-control lever of the GRX series offers outstanding ergonomics. The crisp switching operations are short, precise and can be carried out with little finger strength. This means you never lose control of your bike, even in hectic situations.
The brake lever was also designed in such a way that it can be stopped quickly at any time from any gripping position. It is slightly bent inwards and the axle of the lever has been moved up. This improves ergonomics and at the same time reduces the manual effort required. In addition, the reach of the brake lever can be individually adjusted so that bikers with smaller hands can also ride safely.
The flat-mount brake caliper improves braking performance and controllability in all conditions. Maintenance work, such as venting or changing the pads, can also be carried out easily. The L03A brake pads with cooling fins help to keep the brake temperatures low, especially on long downhill runs.

servo wave action
The Servowave Action technology allows you a short brake lever travel until the pads are in contact with the brake disc. After the brake pad has come into contact, the power transmission factor increases quickly, so that a large part of the lever travel is still available for targeted braking force dosing.
