Because of the inner housing, there's no way to attach any sort of string or fish line that I could figure out (the inner housing doesn't allow much space for any kind of attachment. I tried super-gluing but it didn't hold. And to make the bend, the FD shift cable can't be too stiff at the leading end).

That sounds similar to my Orbea, that had the thin tubing on the wire inside the frame. I assume it was to avoid friction with some foam pieces inside the frame. It's the same tubing I referenced in
my post above. I slid a long section of tubing onto the end of the wire, and pushed the new tubing into the frame as I pulled on the wire at the front exit.
