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.

toss it in

  • Familiarity:I've put it through the wringer

it's nice to have one of these on the trail, Ive needed to loan mine out to others who have bunged up theirs pumping up their tire and being a little too rough.

You can also steel them from old tubes as well as they are universal and save some dollars. I feel for $3 it may be over priced by $2 but I would pay $20 if I needed one and didn't have one on the trail.


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.
