I purchased a Shimano Di2 D-Fly Unit (SM-EWW01) and made this video while I installed it on my bike. On the bike I have Shimano Ultegra Di2 6700 and the firmware was too old. I had to go to LBS and ask for an upgrade to make everything working as in video.

What you need:
- Shimano Di2 D-Fly Unit SM-EWW01
- Extra piece of Electrical Cable
- Di2 Plug tool

Enjoy and thanks for watching! #ride4fun
