Dura-Ace Di2 SW-R9160 11-Speed TT Shift Switch

Shimano Di2 offers faster and more precise gear changes compared to traditional mechanical systems. The electronic signals used in Di2 eliminate the friction and lag associated with cables, allowing for smoother shifts, especially under load. This means you can focus more on your ride and less on gear management.

Shimano Syncro Shift automatically manages gear shifting between the front and rear derailleurs, ensuring you are always in the optimal gear combination. This feature simplifies gear management, allowing you to concentrate on your performance without worrying about shifting at the right moment.

Aerobars are specialized handlebars that allow you to adopt a more aerodynamic position while riding. By reducing wind resistance, they help improve your speed, especially during time trials and triathlons. The design includes arm rests, which provide comfort and stability, enabling you to maintain a powerful and efficient pedal stroke.

Bar end shifters are strategically placed at the ends of your aerobars, allowing you to change gears without moving your hands from the aerodynamic position. This is crucial for maintaining speed and efficiency during races, as it minimizes disruptions to your riding posture and keeps you focused on the road ahead.

The programmability of the Di2 system allows you to customize how the shifters operate according to your preferences. You can set specific functions for button presses, such as choosing whether a press results in an upshift or downshift. This personalization enhances your riding experience, making gear changes more intuitive and efficient.

Yes, you can upgrade your existing bike to include Shimano Di2 and Syncro Shift, provided your bike is compatible. This upgrade can significantly enhance your shifting performance and overall riding experience. Consult with a local bike shop or a professional mechanic to determine the best options for your bike.
