Stan's No Tubes Race Day Tubeless Sealant

While it works, it is not recommended for daily use. This formula is optimized for race-day performance and requires more frequent maintenance than standard sealants, so it is best reserved for events where speed and rapid sealing are your top priorities.

The sealant contains a high concentration of XL sealing crystals designed to plug larger punctures. These crystals are too large to pass through a standard valve core, so you must pour the liquid directly into the tire casing during installation.

Race Day sealant features a thinner, lower-viscosity liquid base packed with twice the amount of sealing crystals, including larger XL crystals. This combination allows it to seal larger punctures much faster than the standard formula, though it does not last as long between top-offs.

Yes. The formula is engineered to remain stable and effective in temperatures as low as -30 degrees Fahrenheit, making it a reliable choice for cold-weather racing.

Because this is a high-performance, race-specific formula, it requires more frequent monitoring than standard sealant. We recommend checking your levels every few weeks, especially if you are riding in dry or hot conditions, to ensure you have enough liquid to seal potential punctures.
