Anyone who rides tubeless tyres knows No Tubes. The American sealant has been sealing holes in tubeless tyres for years. The Race Sealant is now brand new: with larger latex particles for larger holes.

Anyone with open eyes at the Stan's stand at the BIKE Festival in Willingen stroll past, it's not just the new Stan's logo that will catch your eye. Mareen Werner, Marketing Manager at Sport Import, has also the new Race Sealant from the American manufacturer in your luggage - or in this case in your hand.

More particles with a larger diameter

The Race Sealant has been diligently tested in the professional circus for several years and is now finally available for end consumers. The sealing milk contains around twice as many latex particles as the standard milk, and the bottle also contains so-called XL particles. These are designed to reliably seal even large holes up to eight millimetres in diameter. Stan's has also worked on the liquid itself. Holes in the tyre sidewall should now be sealed even faster than before.

Minor disadvantages in the application

However, the Race Sealant also has a few disadvantages due to its ingredients. Due to the extremely high proportion of sealing particles, the milk cannot be poured through the valve as usual, as it would otherwise clog. In addition, the Race Sealant will only be available in a 946 ml bottle because the contents would clump together too quickly in smaller packaging.

Incidentally, the standard sealant will still be available. We have already stuffed a few bottles of the new Race Sealant into our pockets and will be reporting on it in more detail soon.
