Work well
Items as described, work well in my mtn bike. I end up needing to replace mine every so often as I use slim in my tube and it ends up effecting the sealing ability of the valve stems. Read more
Sturdy Build and Great Value.
My cores got clogged by sealant and I couldn’t inflate the tubeless tires on my bike. I cleaned off the gunk, but then the core leaked. My LBS mechanic recommended that I replace the core when it gets clogged rather than trying to clean it. These are well made and a really good deal. Read more
Good for the price
Good cores for the price. Cores get gummed up from tubeless sealant, I'm using these as replacement when needed. Haven't had issues with leaks yet. Read more

Tastes great, less filling... They're valve cores, just buy them if you need some.
Presta valves - - if you use tubeless sealant in your bike tires, you're going to end up with clogged valve cores eventually. Seems like I have to replace mine about every other year, and these are cheap and work as they should. Read more
