Shimano GRX Di2 ST-RX815 hydraulic control lever + BR-RX810 2x11S
The Shimano GRX DI2 Dual Control lever guarantees light and responsive shifting for use on mixed surfaces. The ergonomic design increases comfort and the lever with non-slip surface increases control over rough terrain. The DI2 version offers the digital precision of electronic shifting and Shimano synchronised shifting.
Thanks to the low-profile Flat Mount design, the Shimano GRX BR-RX810 hydraulic disc brakes offer more control on mixed terrain.

Technology
E-Tube
The E-Tube platform's “Plug & play” and D-Fly wireless connections make it easier than ever to check the system's status, and apply customized settings to DI2 and Shimano Steps components with a PC, tablet or smart phone.
Benefits & Features
- Wirelessly customize functions like Shimano Synchronized Shift over Bluetooth® while out on a ride.
- Automatically checks for firmware updates on each startup to ensure all components are running the latest version.
- PC, smartphone and tablet applications can help you quickly diagnose errors and simplify the repair process.
- Beautiful visualization of your real-time Shimano Steps riding data on your smartphone.
- Advanced all-weather design resists rusting, stretching, and freezing.
Reach Adjust
Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.
DCL (Dual Control Lever)
It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from Shimano's MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration, and simply has to be experienced to be understood.
The 105 Dual Control Lever has an optimized structure with features that include the lighter weight pivot section in the near side of the shifting unit and the integral shifting cable for lighter steering. Its many component parts are made so compact and precise to achieve unprecedented high-speed performance.
Ice Technologies
The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.
One Way Bleeding
“One Way Bleeding” was developed for quick and easy prevention of air in Shimano's hydraulic system. They've streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.
