The last 15 years Stans has been developing a special formula of sealant for the most successful racing teams. Taking into account the needs of athletes who push themselves and their tubeless systems to the limit, a patented sealant formula with double sealing standard value was developed, which, thanks to the addition of special "XL" crystals, can even seal huge punctures. Large and small crystals of Stan's Race Sealant combine to form a mesh that not only seals, but also strengthens the puncture area, taking the sealing properties to a qualitatively new level. The quality and size of the crystals in the special formula require the Stan's Race sealant to be poured directly into the tire. Stan's Race sealant is only available in quart size (946 ml). Specifications: • Purpose: tubeless and converted standard tires • Volume: 946 ml Features: • Depending on usage conditions, one dose of sealant is sufficient for a period of up to 6 months of use • Improved sealing capabilities • "XL" crystals and standard size crystals combined for sealing large punctures • Allows for riding in a wider range of conditions and temperatures • Works at temperatures down to -29°C • Premium latex with low viscosity covers the tire sidewalls for faster sealing • Eco-friendly • Composed of natural materials • Must be poured directly into the tire • Can completely cover any nipple or valve.
