SHIMANO GRX Di2 Disc Brake Set Shifter / Brake Lever BL- / ST-RX825 + BR-RX820 Flat Mount | 1x12-speed | single

Ever since Shimano launched the GRX, a specific groupset for gravel riders, it has been synonymous with reliability, durability and functionality. After minor optimizations, the Japanese company has made a major leap with this version. Thanks to the 1x12-speed drivetrain, contemporary wireless control and the usual outstanding build quality, there are no limits to your bike dreams and you will have a loyal companion for your adventures.

The GRX shift/brake levers have a grip geometry and surface texture specially optimized for gravel use. The upper hump has been raised to prevent you from slipping forwards on rough surfaces and the shape has been optimized for wide-spread use.And to prevent your hands from sliding back and forth even when riding in the rain, a non-slip material has been selected which also has good damping properties and therefore increases comfort.
Shifting is done at the touch of a button. This is quick and effortless. The pressure point is so precise that unintentional gear changes are practically impossible. This wireless system is also fully customizable with the help of the Shimano E-Tube app. Among other things, the shifting speed can be set, a fully or semi-synchronous shifting mode can be selected and the program buttons on the lever can be assigned specific functions. Energy consumption is also very low. According to Shimano, the two CR1632 button cells should supply the electronics with power for over 3 years. The absence of wiring not only simplifies installation, but also gives you a neat and tidy cockpit.
The GRX brake lever has been designed so that you can stop quickly from all grip positions at any time. It is slightly bent inwards and the pivot point of the lever has been moved upwards. This improves ergonomics and at the same time reduces the manual force required. The lever has an anti-slip coating to ensure that your fingers rest securely on it, even on bumpy roads, and the grip width can be individually adjusted so that even bikers with smaller hands can ride comfortably.
The flat-mount brake calliper improves braking performance and modulation under all conditions. Maintenance work, such as bleeding or changing pads, is also easy to carry out. The L05A Brake Pads with cooling fins help to keep braking temperatures low, especially on long descents.
