I don't know if this of help to anyone, maybe its old news or doesn't matter, but I figured I'd post it anyway. I don't really like to buy anything new if I can help it, and I recently discovered how to un-stick really tough old bicycle brake cables (-this probably works on shifter cables too). If you have tried Kroil/Wd-40 and gentle working of the cable and can't get it freed up, You can pull the housing straight, clamp it gently (but tight enough to withstand some pulling) in a vice, and clamp vise grips on the ball end and pull it free with a little effort. (Just be careful not to pull too hard and pull the cable through, because the brake cable ends are usually frayed and don't push back through easily). I've done this a couple times, it seems to work great and doesn't hurt anything. Save $15 and keep those old cables. :lol: Hope this is useful.
