How can I load the Di2 on the ST2 S or ST5?

The Shimano XTR Di2 is the first electronic mountain bike circuit. In place of a mechanical connection between the shifter and rear derailleur, the switching pulses are transmitted electrically. This provides Shimano a precise 100% control. Because there are fewer mechanical parts, there is lower maintenance and improved gear changing.

Wherever there is electronics, there is also a controller. This is completely integrated in the Di2 display, with the XTR Di2, all important information such as state of charge, gear position and change mode are shown here. Also the battery is charged via the display.

Is the battery in your Di2 circuit empty? - no problem. The ST2S is equipped with a USB charging socket.

You must consider the following when you charge your Di2 battery through your Stromer:

  • ST2 Ladegerät an Stromer anschliessen
  • Stromer einschalten
  • Di2 Ladegerät an Stromer USB Ladebuchse anschliessen und mit Di2 Einheit verbinden

Per charging cycle you can cover a distance of up to 2500 km depending on the switching behaviour and temperature. A full charge takes approx. 90 min.
