The Stan&';s Race Day Tubeless Sealant is a high-crystal-concentration tubeless tire sealant developed in collaboration with world-class athletes and their mechanics, targeted at riders preparing for race day or long-distance events. Built on the same proprietary liquid base as Stan&';s Original Tubeless Sealant, the Race Day formula increases sealing crystal content by 200% and adds XL-sized crystals capable of repairing larger punctures than the standard formula. The sealant must be installed by pouring directly into the tire over the bead - it is not compatible with valve-core injection or syringe-style installation tools. Stan&';s recommends visually inspecting sealant levels every 2-3 weeks to monitor liquid volume, as the Race Day formula has a faster dry-out rate than the Original. One liter seals up to 16 tires, with per-tire volume requirements varying by tire size - consult Stan&';s sealant volume charts for tire-specific guidance. Formula contains 200% more sealing crystals than Stan&';s Original Tubeless Sealant formula Added XL-sized crystals extend puncture repair capability to larger cuts and holes Shares the same proprietary base formula as Stan&';s Original Tubeless Sealant Must be poured directly into the tire over the bead, valve-core or injector installation is not compatible Stan&';s recommends inspecting sealant levels every 2 3 weeks to monitor liquid volume Store in a cool, dry place away from direct sunlight and extreme temperatures to maximize shelf life Stan&';s Race Tubeless Tire Sealant Tubeless Sealant UPC: 847746067825
