The seatpost mount would be ideal, but how many seat posts have holes going from inside the tube to the outside? Neither my Canyon VCLS 1.0 nor Specialized CG-R do. I won't drill a seat post, particularly carbon.
I believe the Easton alloy post I use has such a hole on the top, but begs the question as to how you get the e-tube wire past the battery in the post. Seems you’d have to modify the battery holder.
I would think at that point I’d rather use the bar end A Junction and get a bar designed for Di2 cable. I’m not retentive enough to want to spend the money for a different bar, but if it were a new build and I were buying stem and bar as new, I’d likely go this route.
