I'm considering fitting Di2 to my P3. I don't like the downtube battery mount so wondered if I could hang the battery between the tri-bars, swapping the A- and B-junctions over (I could position the junction A on the chainstay) to save on those expensive wires.

With a proper tube clamp and not the 'Heath Robinson' arrangement here, I reckon it'll work. My question is, why have I never seen anyone else do this? What am I missing? To me, there is little aero drag induced by this as the flow will already be turbulent by the time its gone over my hands and G500!

The main difference in swapping junctions is where in the chain the battery is. I don't know what the ramifications are of having the battery before the front junction. If I was going to do something semi-custom on a p3, I'd put the battery behind the seatpost clamp, right above the rear brake. Could improve aero there.

True, but how do you run a wire to it? Would you have to run it on the outside or drill?
