What am I supposed to use here as a cable ferrule for a normal derailleur cable (the short piece that attaches between the actual derailleur and the frame)? A normal cable ferrule doesn't work because it is too wide to insert into the cable stop braze-on. Last time I used a raw cable without any ferrule, it started coming right through the cable stop braze-on. I'm surely botching terminology. I don't know what to call this stuff.
I see old-school bikes with a short wire coil that appears to be just the inside of a modern cable, but slightly wider.
