Have you tried Red?

I tried it didn't get on with double tap.

I think Di2 is too first generation. I rode it (150km over a weekend) and it shifted flawlessly. For pure bling's sake the battery and the cables were an eye sore.

My vote:

- If you get an internally routed Di2 frame then get Di2

Personally I would get 7900 and upgrade other parts. maybe go full custom on the frame.

Hey, it's a great "problem" to have!
