🔧 10-Pack Presta Valve Core: Convenient and Cost-Effective Solution Review

I had some small tire leaks and thought it was the tires. At least that's what I thought when the sealant deflated the tires. However, I bought them as a last resort. It worked and the tires held air for weeks.

After riding without tubes for about a year, I noticed that the airflow in and out of the tire became slower after a few months of using sealant. For just a few dollars, you can easily fix this problem by swapping out the valve cores, and they've worked great for me.

Eventually your valves will stick together when using tubeless pumps. So instead of replacing the whole valve stem, I just keep extra cores on hand for when they start to leak or it becomes difficult to add air. Put in a new core and it will be like new. Good price!

What can I say other than it works. You plug it in and it either works or it doesn't. And this one works. 10 packs may seem like a lot at first glance. If you have a tubeless tire that needs sealant every few months, your valves are going to clog sooner or later. You will eventually use up all 10.

One of the cores of the Presta was bent and not holding air. But the biggest problem is that the main body (threaded part) is made of PLASTIC. In all my years of cycling, valve cores have always been metal. Where the world comes up :-( I wouldn't trust them to withstand regular use or withstand exposure to tire sealant.

In the picture you can see my old OEM tubeless valve core next to this one that replaced it. These cores have a slightly thinner thread and have a smaller mount at the bottom. Once installed they hold air and work flawlessly. No complaints and the price is fantastic. The OEM tubeless cores were $2 each, and these $10 for $7 is a fantastic deal.
