A friend recently bought an old cruiser from the 70's or so. A quick overlook of the bike that it's previous owner really knew how to take care of it. I'm sure this is rare. Aside from a rear wheel slightly out of true and a barely-loose BB, it was fine. However, she wants to somehow replace the black wire ties that are holding the brake and shifter cables on the top tube. Can you use housing stops for brake cables? I assume you can't considering how tight they would need to be to accommodate braking force.
Just thought of something. White wire ties. The frame is yellow, the housing wight.
