Developed in collaboration with world-class athletes and their mechanics, Stan’s Race Day Tubeless Sealant delivers highly effective puncture protection for riders of all levels during races and long-distance events.
The Race Day blend starts with our Original Tubeless Sealant and boosts the sealing crystal content by 200%, then adds XL-size crystals to tackle even larger holes. For best results, visually check liquid levels every 2–3 weeks to ensure optimal performance.
One liter of Stan’s Race Day Tire Sealant will seal up to 16 tires—see our sealant volume charts for detailed guidance. Note: it cannot be installed through a valve; install directly into the tire over the bead.
