Inside Stan's simple black bottle is a product that's changing cycling. Just two ounces of Stan's Tire Sealant in a converted standard tire or tubeless tire can repair punctures up to 1/4" almost instantly to keep you rolling.

Arid conditions require more frequent monitoring of sealant levels, but anti-freezing agents in our special formula allow Stan's Tire Sealant to be used in temperatures as cold as -30° F.
