GCN shows you how to install a Shimano Di2 electronic groupset. If you have Di2 on your bike, the chances are that it either came pre-installed, or that you had it installed by a bike mechanic.

GCN breaks down the complex aspects of the installation of an electronic groupset, making it a more approachable task.
