The Original - the world's first sealant for tubeless tires. Developed in 2001 by Stan Koziatek, who named both the product and the manufacturing company. What began in a garage back then revolutionized the bike industry. Stan's NoTubes has become the industry leader and remains the top choice for riders around the world when it comes to tubeless solutions. Recommended for general use, it is compatible with all tubeless road, gravel, and mountain bike tires, as well as tire inserts. The original formula is the best choice for reliable puncture sealing at temperatures between -28° and +50° C for up to 7 months. Stan's NoTubes Original sealant quickly and permanently seals holes and cuts up to 6.5 mm in size. Safe for both humans and the environment, the sealant is made from natural latex and contains no toxic or hazardous substances. The bottles of Stan's Tubeless sealant are made from 30% recycled material. For optimal recycling, the labels can be easily removed. One liter of Stan's Original sealant can seal up to 16 tires.
