All my Silcas have died of old age, or in one case, being run over by my wife. It's more than a little sad, they are very good pumps. I still have a stash of Campy heads for them though. If it's taking a long time to pump up a tire with a Silca, it's possible that the main tube has developed a hairline crack. That's how my first one died.
I now use a combo CO2/pump. Eric Keller Boalsburg, PA
