is it possible and/or clever to run EPS/Di2 wires through outer cable?
Pretty astonished that there aren't 500 results for this issue in google already???
Going to hopefully buy a cool 90's ti frame really soon so I'm figuring out how exactly to throw EPS on it.
I've read a small bit about drilling ti and am aware that spots like the end of the chainstay can be drilled without too much risk of frame death but obviously pretty much anywhere on the downtube is a different story
however this thread is NOT about the well covered topic of drilling. its an option, but I'm curious if running the wires through normal outer is actually problematic, or if its just so counter-intuitive to what EPS/Di2 is about that it hasn't occurred to anyone?
I'll be keeping everything on the frame (downtube shifter lugs + adapters etc) to have it set up for mechanical at some point in the future anyway. all those bits are in really good shape - running the wires through outer doesn't immediately jump out at me as being dangerous or silly as it makes adapting an old, non e-group frame VERY straightforward (read no adapting at all). the only downside I can see is adding weight that egroups are primarily designed to erradicate... add that to the battery, brain etc and there would be just about no point unless you have a fetish for clinically good shifting.
thoughts?

The end connectors on the Di2/EPS cables would not fit through any cable outer. Unless you cut the wire and re-attached it. Even then you will still struggle to found a cable outer that's wide enough.
Also you will still have a long section of exposed cable for the downtube and chainstay. Seems like a lot of faffing for such small sections of cable.
What's wrong with just a normal external set up ? If its too much exposed cables, then how does adding normal outer make it any better ?
If you do drill the frame. The bottom bracket shell needs to have 3 holes in it also if it hasn't already.

This works good. I used them for a wired Power Tap.
