E-TUBE
E-TUBE is Shimano's “service” that uses websites or apps to maximize the enjoyment of riding a bicycle by connecting the riders, the bicycles and SHIMANO. SHIMANO’s genuine application E-TUBE PROJECT for Mobile allows you to customize your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get the more detailed bike maintenance by connecting to your bike by wire with E-TUBE PROJECT for Windows V4 application.

Bluetooth LE
The most groundbreaking technology featuring  is a new wireless Bluetooth connection to Shimano’s E-TUBE program, which is the system Shimano uses to set up and control the Di2 shifting behavior. Through Bluetooth technology riders or mechanics can wirelessly communicate with their computer, tablet or a smart phone via the wireless unit (EW-WU101/EW-WU111) or the system information display (SC-MT800/SC-M9051) and a new battery (BT-DN110) or battery mount (BM-DN100). As well as allowing wireless workshop customizability, it allows riders to customize their shifting preferences on the trail via an app on their smartphones.
