I ordered that cable mentioned above and have a question. In all of the videos and instructions I watched, the cable goes from the lever to the front of the top bar in housing, a ferrule is attached and the bare cable runs along the top bar of the frame, connects goes back into housing at the rear all the way to the brake. Mine goes in housing from the lever to the front of the top bar, a ferrule attaches there but then the cable is run in a thin jacket all the way to the brake, going inside a metal tube around the seat post. I attached some photos. How do I run this new cable from where it comes out of that ferrule in the front all the way to brake? Should I just remove that thin jacket and try to put it on the new cable? Should I run it bare? There is place to attach a ferrule in the rear of the bike.
Cable running along top bar to rear brake.
