Stan's NoTubes Extra Tubeless Valve Core $3.00
We sell this Stan's No Tubes Extra Valve Core because valve cores are inevitably easy to lose. The O-ring that seals the valve core inside the stem can also be damaged, causing leaks in the system. So whether you've lost yours or simply need a replacement to restore the performance of your tubeless tire system, this valve core will get the job done.
What community has to say
Like carrying a a tube
You're valve core will fail and need to be replaced at the worst, most inconvenient time. I carry an extra in a little pouch with extra chain leak and tire boot. You can prepare to handle repairs, or prepare to walk.
Good To Have An Extra
My pump destoyed one of these. Probably user error. Now I keep a few extra in my toolbox.
