Shimano 105 Di2 12 Speed Disc Brake Groupset

With its original ground-breaking electronic Digital Integrated Intelligence (Di2) shifting system launched in 2009, this latest version of Shimano Di2 features critical functional enhancements, including a wireless cockpit and the jump to 12-speed. And it’s all been done without any sacrifice to the fast, precise and reliable shifting riders have come to expect from all Shimano road groups. Changing gears is simple and consistent all the time, every time. SHIMANO 105 Di2: Wireless where it matters Shimano 105 Di2 utilizes 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 absolute reliability in all conditions. And just like DURA-ACE and ULTEGRA, the Shimano 105 Di2 system is highly customizable using Shimano’s user-friendly E-TUBE PROJECT App on your smartphone. With E-TUBE PROJECT you can set-up your drivetrain just the way you like it, adjusting shift speed, altering the number of shifts per button actuation, and utilizing the Synchronized and Semi-Synchro shifting functionality. You can also pair the system with most third-party cycling computers, including Garmin and Wahoo, which allow you to monitor gear selection or battery status.
