Shimano’s new Ultegra electronic shifting is faster and more accurate shifting than any mechanical system available on the market today. It is everything you want in your shifting system: short finger strokes and now with a simplified modular wiring system. Ultegra Di2 makes it easier than ever to add digital electronic shifting to your riding experience.

Dura-Ace Di2 has been proven over and over by professional riders for the past 4 years through the highest mountains, the worst cobbles and through the most extreme weather conditions imaginable. It's just the same as for Ultegra. Changing gears becomes easier, effortless and faster by simply touching the shift buttons. Control at your fingertips. Additional benefits include an automatic trimming front derailleur, great accuracy plus easy adjustment and installation.
