Experience the ultimate sealing solution with Stan's NoTubes Race Tyre Sealant Quart. Trusted by professional mechanics and athletes at top-tier events worldwide, this formula has been painstaking designed by Stan Koziatek himself for unbeatable performance under extreme conditions.

Our race sealant has been in development for nearly fifteen years, backstage at the most challenging cycling events. It's the secret weapon of the world's top teams, who need their tubeless systems to perform flawlessly even under maximum strain. Now, we're bringing it to riders everywhere.

Stan's Race Sealant features almost twice the amount of our standard sealing crystals, together with our unique ""XL"" crystals that can tackle even larger punctures. This combination of large and small crystals doesn't just seal ? it creates an interlocking lattice that reinforces the puncture area. The result? An unprecedented level of performance, keeping you pedaling when others would be forced to pull over and repair.

Please note, this highly efficient formula must be poured directly into the tyre, as it will clog injectors and small bottles. Stan's Race Sealant is suitable for a wide range of conditions and temperatures and it is environmentally friendly, being comprised of natural materials.
