Shimano Di2 Setup Using E-Tube App: Synchro Shifting, Gear Changes & More!

In this video I explain how to customize your Shimano Di2 electronic drivetrain using Shimano’s Android or iOS E-Tube Project Cyclist smartphone app. While this tutorial uses the iPhone version of the app, the Android version works the same way. I am demonstrating the app using the Dura Ace Di2 9170 disc groupset, but the app is used the same way across all of the Shimano Di2 groupsets for road, mountain and gravel.
