This weekend I experienced the joy of a nonfunctioning pump far from home. Turns out the female threads on the plastic pump head didn't seem to match the threads on the pump end (also plastic). Why it stayed together this long I don't know. I hadn't stripped this one down for cleaning and shining since it was headed for a user bike. Just greased the cup. Won't be doing that again! I vaguely remember that there were different ends but of course didn't pay attention. I thought the Campy head replaced the standard pump head but there were others?
