Stans NoTubes TYRE SEALANT RACE QUART (32 FL OZ)

The Next Level in Sealing Power from the People Who Invented Tubeless Conversions.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, and formula notes by the man himself, Stan Koziatek.For nearly fifteen years Stan has been quietly formulating a special racing version of his legendary sealant for many of cycling's most successful teams. Working with athletes pushing themselves and their tubeless systems to the absolute limit, they've developed a proprietary sealant formula with nearly twice the amount of the standard sealing crystals plus their 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.The quantity and size of crystals in this special formula means that Stan's Race Sealant can only be installed directly into the tyre. As a result of its immense sealing capabilities, Race Sealant is not compatible with injectors or other valve installation methods. Race sealant should be inspected every 2-3 weeks for best performance. Be sure to rinse race sealant from used tyres intended to be stored/reinstalled.They are now making their Race Sealant available to riders everywhere. Stan's Race Sealant is only available in 946ml bottles.Race Sealant is incompatible with sealant injectors or other installation methods through the valve. Race Sealant must be poured directly into the tyre.
