Product Details

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 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 10mm of cable stroke for compatibility with many dropper post options. As far as braking is concerned, it provides 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.
