If you do get a pump. Get a hose attachment with it so you don't yank the valve stem out. I know there'll be many thousands who do this successfully with no hose. But do you want to be on the roadside and find out you aren't one of them?
Whoa! Do you mean the valve core got pulled out? Pulling the valve stem out of the tube seems…incredible! If it was the valve core, any idea why they didn’t just screw it back in?
Some complain of Lezyne hose pumps— which thread on— unscrewing valve cores when removed if not done with care, and I’ve pulled a core from a plastic valve stem with a fixed head Specialized Air Tool Road pump once, but I’d have thought that was rare, because most valve stems are metal, I think. Anyway, I was able to screw the core back into the stem without any problem, so maybe it was loose when I started and I only stripped a couple of stem threads pulling off the pump…
But yeah, hose pumps are a lot better to use and I prefer them, too.
