I'm planning on doing the above. The first obvious problem is getting the 5mm cables to pass into the frame; do redundant/empty downtube shifter bosses leave a hole that passes into the frame that a di2 cable could be threaded through?
I'd need one hole at the front near headtube, and one at the rear (1x11 setup, so no front derailleur). If I did have to resort to drilling, what locations would least compromise frame integrity?
