Over the years I've had numerous floor pumps, been somewhat of a sucker for floor pump tech
One by one they all developed an issue(s) and parts got hard to get. The only pump that hasnt is my trusty OLD Silca floor pump(s). The one I have now has to be 15+ years old. I pulled it out of mothballs a few months ago after not using it for many years...greased the leather washer, dusted it off and she works like a charm. I'm replacing the hose and pump head to the new Silca Shraeder/presta head and I think she'll give me 15+ more years..
cheers
