They are priests valve cores. Should be easy right? Not. I tried 2x other valve core listings on Amazon. For some reason my pump wouldn’t lock on to them and they wouldn’t allow me to add air. Refrained from valve cores on Amazon as a result till the bike shop had none in stock. Needed some desperately so I tried these. They worked perfect. Will order more in the future.I don’t know how valve cores aren’t pretty standard but the last 2 listing didn’t work at all. Been a competitive cyclist for 35 years. Never seen a valve core that don’t work but some how Amazon has some listing that don’t.

If you're using tubeless tires, then you must adapt your bike maintenance habits.One useful tip is to be sure to have a handful of spare valve cores on hand.It's common for valve stems to get gunked up with sealant, causing them to stick and become difficult to loosen.I've found it convenient to replace the valve cores every few times I've topped up the sealant to ensure everything is functioning smoothly.These cores from GXXMEI are inexpensive and well-built. Throw a bag of them in your toolbox, and you'll be set for a couple years.

These are generic valve cores - absolutely nothing distinguishing them from the countless others available on Amazon and elsewhere. They're all about the same price, and do exactly the same thing. Sometimes valve cores get bent or clogged and you have to replace them - simple as that. Nice to have a bunch on hand at all times. These will do the job.
