Hi!
I recently purchased a Scott Plasma TT 2011 frameset and built it up with Ultegra Di2 6770 components. I'll try to answer some of the Di2 related questions.
"For those of you who have the Di2 specific frame, do you know if it's possible to do the entire wiring internally?"
Yes, with the original flat stem and the PRO Missile Evo bar, wiring can be done completely internal (except for the front brake and the derailleur cables). If you'll use another aero bar, most likely at least some cables will be exposed.
"Also, where do people mount their batteries? And i presume i could also get the internally mounted battery?"
I bought a SM-BTR2 internal battery and put it into the seatpost. It works like a charm, no cables exposed and no rattling of the battery.
"Finally, has anyone here managed to put the junction box inside a flat stem?"
I tried my best but unfortunately was not successful. Neither the SM-EW90-A nor the SM-EW90-B will fit. The height would fit after grinding off some plastic elements used for strap mount of the front junction box. Yet the length including the plugged in cables will be too long for the cavity of the stem. I have the 75mm flat stem so possibly the junction box might fit into the 90mm stem.
"Otherwise I assume 300 mm is enough for the FD and Battery (to the rear junction) and 500mm is enough for the RD? Or is 450mm sufficient?"
I used the following cables:
1x 500mm RD to rear junction (450mm will be too short!)
1x 250mm FD to rear junction
1x 250mm Battery to rear junction
1x 950mm rear junction to front junction
The brifters and extension shifters have pre installed cables.
Have a look at
