I guess I'll check all my tubes before I put them in my tool bag, but I'm not happy about this. I ended up getting back on my route by flagging down a cyclist and using his pump, the kind you just push on and pull off.
1973 I went from the hosed Zephal of my Peugeot UO-8 to the HP for my next bike. That press on with clamping lever was so good I have never wanted to go back. Of course, I had to learn to not put my pumping force into the valve stem but that's like learning to walk or tie your shoelaces only easier. And like them, you only have to learn once. Now there are so-called good pumps that feature hoses and screw on fittings. I just shake my head.
