Overview
Shift/Brake Lever Shimano 105 Di2 ST-R7170-L 2-speed (2x12)
The new SHIMANO 105 Di2 ST-R7170 left shift/brake lever introduces Di2 electronic shifting to the 105 series for the first time, delivering precise and intuitive front shifting to a wider range of road cyclists. Reach adjustment and customizable button functions allow fine-tuned ergonomics.
Inspired by SHIMANO’s The Science of Speed philosophy, the next-generation 105 Di2 delivers fresh momentum, comfort and control. It encourages riders to explore the open road with confidence and efficiency.
Drawing technologies from DURA-ACE and ULTEGRA, SHIMANO 105 Di2 transforms the road cycling experience for riders upgrading from mechanical shifting. A shared Di2 platform, refined ergonomics and a powerful hydraulic disc brake system define a new era of accessible performance.
The wireless minimalist cockpit eliminates visible cables for a clean and aerodynamic appearance. New Dual Control levers provide excellent comfort in all hand positions, especially on long rides. Battery life reaches up to 3.5–4 years using two CR1632 batteries.
