GRX ST-RX810 Left Brake Lever for Dropper Seat Posts incl. BR-RX810 Calliper

Explore beyond!
Discover the almost endless possibilities of modern road cycling with SHIMANO GRX components. The RX800 Series at Ultegra/XT level represents the performance-oriented top range of SHIMANO’s gravel- and cross-specific GRX groupsets.

The GRX ST-RX810 STI shift/brake levers with gravel-specific ergonomics are your control unit for maximum shifting performance and outstanding control on rough terrain. The left GRX BL-RX810 brake lever for easy 1x11 drivetrain configuration comes without shifting function, but instead with the option of operating a mechanically-driven dropper post. The STI-lever can also become a remote lever for the dropper post. So your dropper post integrates visually with a gravel or cross bike, while also being fast, easy, and intuitive to operate.

Featuring an 18mm higher axis point than “traditional” SHIMANO road shifters, a curved brake lever profile and an anti-slip textured finish, the levers offer best grip on rough gravel roads and challenging cyclo-cross rides. Yet, the GRX levers also impress with high comfort and reliability on bike-packing adventures with lots of luggage and on daily commutes to work.
In combination with a powerful hydraulic BR-RX810 Flatmount disc brake, SHIMANO offers you a braking system with great braking performance and comfortable braking power modulation thanks to the SERVO-WAVE technology. This provides high safety when riding your gravel bike in bad weather. A wide lever reach adjustment range tops off the package.
