Shimano GRX Brake Lever Remote ST-RX820-LA

Shimano GRX ST-RX810-LA brake lever with remote function for mechanical dropper posts

The Shimano ST-RX820-LA brake lever from the GRX RX820 gravel series is an STI, but instead of shifting, you use it to control a mechanical dropper post. It is mounted on the left side of the drop bars and is therefore perfect for 1x setups, which only require a regular shift/brake lever on the right. The integration of the remote function into the brake lever is not only practical, it also makes for a tidier cockpit. You have a maximum of 10 mm of cable stroke at your disposal. As far as braking is concerned, ST-RX820-LA impresses with more control on mixed surfaces and with ease of use. The lever and lever body ergonomics have been specially adapted for gravel use and for flared handlebars. The aluminium lever has a textured coating to prevent slipping. The reach of the lever can be adjusted with the help of a hex key. The pad engagement point is also adjustable. You also benefit from Shimano Servo Wave technology for a more targeted application and a more efficient use of braking power.

Technology:

Servo Wave
Shimano Servo Wave technology optimises the travel of your brake levers. During the braking process, the brake pads are guided quickly to the brake rotor with very short lever travel. The greater part of the lever travel is reserved for the actual braking force. In this way, you can apply your braking power in a more targeted manner and use it more effectively.
