Shimano EW-EC300 Charging Cable

The Shimano Di2 Charge 12-speed cable is designed to charge your Shimano Di2 12-speed groupset. The Shimano R7170, R8100, and R9200 Di2 groupsets can be charged via this cable on the rear derailleur. The Shimano Di2 Charge 12-speed is also suitable for charging your power meter.

Shimano Di2 app:
All adjustment options, such as assigning shift buttons, shifting modes, or adjusting shifting speed, are available via the Shimano Di2 app. The function of the shift buttons can be individually configured. Synchronized shifting or semi-synchronized shifting, where the front derailleur automatically shifts to maintain the ideal chainline, is still possible.
