Shift/Brake Lever Shimano 105 ST-R7170-R 12-speed (2x12) Di2 

The new SHIMANO 105 Di2 ST-R7170 right shift/brake lever introduces Di2 electronic shifting to the 105 series for the first time, delivering precise and intuitive gear changes to a broader range of riders. Reach adjustment and customizable button functions allow you to fine-tune the ergonomics to your personal preferences.

Built around SHIMANO’s The Science of Speed philosophy, the 105 Di2 combines performance, comfort and control in a clean, modern design. The wireless cockpit eliminates visible cables and ports, creating a more aerodynamic and visually refined setup.

The all-new Dual Control lever design ensures excellent comfort and confidence in every hand position. A raised hood peak and longer hood body provide increased hand support, especially noticeable on long rides when fatigue starts to set in. The hydraulic disc brake system delivers consistent and powerful braking in all conditions.

Thanks to its wireless Di2 connection, shifting is lightning-fast and maintenance is reduced. Powered by two CR1632 batteries, the lever offers an impressive 3.5–4 years of battery life. Button functions can be easily customized using the E-TUBE app, while reach adjustment helps you find the perfect lever position.
