Developed over the last 15 years through close collaboration with the worlds most successful cycling teams. Stan's new Race sealant is the product of careful refinement and unrelenting development.

• New XL crystals combined with twice the sealing crystals of standard sealant give the ability to seal larger punctures
• Premium low-viscosity latex coats sidewalls better for quicker sealing
• Must be poured directly into the tire as it will clog injectors and smaller diameter bottles
• Safe for the environment as it is comprised of natural materials
• 32 FL Oz (Quart) Bottle
