STAN'S race day tubeless sealant - 500ml

Designed for competitive cyclists and long-distance riders, Stan’s Race Day Tubeless Sealant offers exceptional puncture sealing performance to keep you riding smoothly during race day or extended events. Developed alongside world-class athletes and mechanics, this high-performance sealant ensures reliable protection against flats, even in challenging conditions.

Our Race Day formula features the same proprietary blend as our Original Tubeless Sealant but with a 200% increase in sealing crystals. Additionally, XL-sized crystals are added to effectively repair larger punctures. To maintain optimal performance, we recommend visually inspecting the sealant in your tires every 2-3 weeks to monitor liquid levels.

One liter of Stan’s Race Day Tire Sealant can seal up to 16 tires. Please note, it must be poured directly into the tire over the bead—this sealant is not compatible with valve injectors or other installation methods.
