Stan's Original Tubeless Sealant

Still works

Have used Stan’s for many years in the rocky gnarly trails of Phoenix. Couldn’t ride without it.

The best out there

Love Stan's for many reasons, it's the easiest to wash out by just rinsing, the bottle has the amount you're supposed to put into a given tire on it, and the easy pour cap makes it easier to load up into a new tire

good stuff

I don't get flats with Stan's. it must be working. i won't ride southern california trails without stan's sealant
