The frame splits in two for easy transport, so I had to think of a way to allow the cables routed to the rear of the bike quick release when the frame splits. Centerpull brake cable yokes are used. They look complicated and scary, and they are a pain to adjust initially, but they work well. Plenty of adjustability with all those barrel sleeve adjusters. The top is for the rear brake, middle for the rear derailleur, bottom for the throttle.

Two (blue) quick release seatpost bolts are used as pinch bolts for the split frame. Then there's a big pin that safeguards the two sides from twisting or coming apart. If you look closely you can also see a small, sheet metal fin brazed on to visually align the main tube halfs so the pin can be inserted easily.
