With some of the most outstanding race componentry on the market Shimano has been supplying cyclists of every denomination with the parts they need for many years. A perfect example of their dedication to improving cyclists performance and experience with their equipment is their electronic Di2 family of components.

Tested and proven in the pro circuits Di2 is the culmination of decades of research and development. The cleanest most maintenance free system just got a bit more low profile. With the internal battery stashed inside the frame aerodynamics improve, the likelihood of snagged connecting wires is reduced, and the overall aesthetic of the bike is greatly increased. If you haven’t tried a bike with electronic shifting go out and do so now. Trust us, you won’t be disappointed.
