I took a look at my Scott today cause I need to replace some cables. I discovered that all my cable housings ends with a steel "shoe". Where can I buy those ends to the cable housings? Or do I have to take them off my existing housing and try to fit them on the new housing? That would be a real pain I guess. OR, in case of emergency, could I just pull out the cables and try to fit the new cables in the existing housing, and in that case, should I clean them internally and how do I do that?
