FEATURES: Tested and developed with world class athletes Recommended for race day and long-distance event use Improved sealing capabilities compared to Original Tubeless Sealant formula 200% more sealing crystal than our Original formula, with added XL-sized crystals Must be poured directly into tire–not compatible with injector or other valve install methods DESCRIPTION: Developed with world-class athletes and their mechanics, our Race Day Tubeless Sealant provides highly effective puncture sealing performance to riders of all levels during their own race or long distance event. Our Race Day formula begins with the same proprietary mix in our Original Tubeless Sealant and increases the amount of sealing crystals by 200%. Then, additional XL-sized crystals are added to repair even larger punctures. For best performance, we recommend visually inspecting Race Day sealant in tires every 2-3 weeks to monitor liquid levels. One liter of Stan’s Race Day Tire Sealant will seal up to 16 tires, consult our sealant volume charts for more detailed guidance. Cannot be installed through a valve–must be installed directly into the tire over the bead.
