Stans No Tubes Race Tyre Sealant

If you've walked the mechanics' pits at any National or International level event, chances are you've seen them: trademark Stan's black quart bottles with no labels. Look closer and you might have seen strange symbols scrawled all over the bottles in a silver marker, letters and numbers, formula notes by the man himself, Stan Koziatek.

For nearly fifteen years Stan has been quietly formulating a special racing version of Stans legendary sealant for many of cycling's most successful teams. Working with athletes who push themselves and their tubeless systems to the absolute limit, they've developed a proprietary sealant formula with close to twice the amount of their standard sealing crystals plus our special "XL" crystals capable of sealing even larger punctures. Stan's Race Sealant's combination of large and smaller sealing crystals interlock to form a lattice work that not only seals but strengthens and reinforces the area of the puncture, allowing for an entirely new level of sealing performance.
