As for the housing, I am not sure. Everything on the bike is stock from the complete bike aside from the front rim and spokes, saddle, and accessories I have installed (racks, panniers/bags, computer, etc, etc), bottom bracket, and pedals. That includes the bars, brakes (entire set up - levers, cables, calipers, pads, rotors), hubs, and drivetrain (I only added to the drivetrain, never took anything away - crank and first 3x chain rings are stock). So I don't know what cables/cable housings are on the bike aside from what would have been on it as a complete bike build back in 2014.
