Actually, I was able to get it set up internally. It took me a while to figure out which method would work for this bike, but (in case other people find this post) I ended up using a 4' strip of duct tape folded over the long way. Put a washer for weight on one end and secured the housing to the other. Dropped the washer end down the seat tube, manipulate the frame until the washer goes past the bb andfalls down the down tube... Towards the head tube. .. Once it gets to the head tube, just pull it all through, then you can reach in and push the housing to exit the frame. Takes less than 5 min.
