Silca, hands down. No idea how old mine is: I bought it 10 years ago, used, at a local consignment store. I've replaced the rubber gasket in the head a couple times, and the leather one on the plunger a couple times, and it's still going strong. Literally EVERYTHING is replaceable and available at my LBS. And what's more fitting for pumping up the tires on your C&V bike than a classic pump?
