TOKYO, Japan - After 40 years since its first introduction, the Shimano 105 group set is receiving the ultimate upgrade with a move to Di2 electronic shifting technology. This introduction not only delivers Di2 to an entirely new range of riders, but also offers Shimano's flagship 12-speed, wireless shifting with easy operation and increased reliability.

The category of consumers who have traditionally used mechanical shifting systems can now experience the function and technology inherited from Dura-Ace and Ultegra. Shimano 105 Di2 is the culmination of years of research and development, where wireless shifting, tailored gearing, and an exceptional braking system, mark a new era in affordable performance.

The latest version of Di2 features critical functional enhancements”


Shimano introduced its electronic shifting system already 2009. According to the component manufacturer, “the latest version of Di2 features critical functional enhancements, including a wireless cockpit and the jump to 12-speed. Di2 comes with a completely redesigned Di2 system, an optimized 12-speed gearing, refined interface and ergonomics and an enhanced brake system.”

Backwards compatible

The new system is also backwards compatible, meaning you can use your existing 11-speed freehub-equipped wheels with the new Shimano 105 Di2 drivetrain.

Shimano 105 Di2 utilises a hybrid system, featuring a wireless cockpit paired with a wired connection between a single, seat-tube-stored battery and the front and rear derailleurs, ensuring reliability in all conditions. And just like with Dura-Ace and Ultegra the system is highly customisable using Shimano’s user-friendly e-tube project smartphone app. The system can even be paired with most third-party cycling computers, including Garmin and Wahoo, which allows to monitor gear selection or battery status.
