I’ve got a whole load, built up over the years. Prefer screw-on to push-on.
Cheaper ones are better IMO. The Topeak and Lezyne ones are a good size and push air in at a decent enough rate, but have a bad habit of not only removing valve cores but also – from time to time – refusing to let go of the head of the valve core, which is disastrous.
Best ones I have – a cheapo from Decathlon (like this: https://www.decathlon.co.uk/p/mountainbike-hand-pump-black/_/R-p-306754?mc=8543432&c=black) that just fits into my small Evoc hip pack, doesn’t eat valve cores and puts in air at a ridiculously high rate, and a small French supermarket-looking effort that Mrs Tyred found lying on the ground at the top of Mt Ventoux years ago that’s still going strong.
The Decathlon one was a short-notice emergency purchase for one of the kids, but it’s a brilliant piece of kit. If it was 5cm shorter it’d be a total winner.
