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 Di2 ST-RX815 STI shift/brake levers with gravel-specific ergonomics are your control unit for maximum electronic shifting performance and outstanding control on rough terrain. 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 cyclocross rides. Yet, the GRX levers also impress with high comfort and reliability on bikepacking 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. Fast and precise shifting, bite point adjustment and a wide lever reach adjustment range top off the package.

Tip:
When using the GRX Di2 ST-RX815 brake/shift lever combination together with an uncomplicated 1×11 drivetrain, you can use the buttons of the left lever to control compatible third-party devices like lights or bike computers. (EW-WU111 Wireless Unit (product code:. 2238564) required!)
