From Park Tool, an example of crossing over shifter cables along the down tube. I wonder if your internal cables could do this?
In some cases, it is possible to “cross over” the housing, running the front shifter to the right side stop, and the rear shifter to the left side stop. It will then be necessary for the cables to cross back over underneath the downtube. Consider this option, but if the cable ends up rubbing the frame, it is not a good idea. There may be some light rubbing between cables, but this would result in less friction than poorly routed housing.
That's not an option for this frame due to where the cable comes out of the frame at the BB and then goes back into a hole passing through the chain stays then up to the front DR. The other option would be to cross the cables inside the down tube but I don't think that would be a good idea because the cable would rub each other where they cross and that would surely lead to frayed cables and eventual failure.
I think I'll replace the housing (really hating the red) and start with the shifter cables 1" longer than the current left side housing is. The shorted of the 2 is long enough to allow full rotation of the bars. My original intent was to use a new 5800 group on the bike but wasn't able to get the combination of components I wanted when I tried to order. I really like the way everything is working on the bike but I'm thinking that I may want to get the 5800 group anyway for the way both shifter and brakes cables are under the bar tape. Repurpose this group for a vintage steel bike that will be my next N+1.
