It's a Centurion Ironman model that I found yesterday (see my intro). The brakes/cables work so I don't think I need to replace them. I'm just wondering how to get them free so I can clean up the rust etc. Do these clips come out of the frame? If not, how to I pull the cable out? It seems stuck in there pretty good. What's the best way to clean up this rust? It's pretty heavy. Lemon juice doesn't seem to be working and it's impossible to get at it with the cable in there. I have a Dremel but I don't want to sand them with cable still in.
