Rohloff shift cables for a folding bike?

With the EX box, the cables and EX box stay with the front half of the frame when you split the couplers.

The cables run under the bottom bracket and then under the left side chainstay.  There are some cable holders on the left side chainstay that allow the cables to be hook into the holder or unhooked without tools.

In the first photo those hooks under the left chainstay are visible below the word Thorn, the photo was not taken with showing those hooks in mind so the photo is not that great for your purposes.  But I think you get the idea.  I have no idea if the way those cables are hooked in is patented or not.

Second photo, the cables and EX box stay with the front frame member, as does the handlebar because of my rear brake cable.  This bike uses full length outer housing for the rear V brake too, I disconnected the cable from the rear brake.  I have changed my Rohloff shifter placement after this photo was taken, so disregard the shifter part of this photo.

I can think of other options if you do not use full length outer housing, either that use cable splitters or cable stops on the frame.  But I am sure your frame builder could think up anything that I could dream up.

Third photo is of my Raleigh Grand Prix, that bike uses the Ritchey Break Away system (competitor to S&S couplers), although the bike does not use a Rohloff you can see in the photo that there are cable splitters on the gear cables under the downtube near the coupler.

What Mick wrote.

Our Thorn tandem uses the same system and it is easy enough to roll up the cables with the ex box and attach to the front half of the bike. I use an old toe clip strap to secure it.
The rear brake cable un couples with a screw thread connector and then we have two halves of our tandem.

CanAmSteve:
Many thanks for the helpful information and tips. I agree removing the shift box and coiling cables with the front frame half seems the best solution. If I go with a mechanical rear disc brake then I can use a cable splitter on that run. The tip on using tube sections to reduce grit in the couplers is also heandy. Thanks again
