Developed with world-class athletes and their mechanics, the Race Day Tubeless Sealant provides highly effective puncture sealing performance to riders of all levels during their own race or long distance event.The Race Day formula begins with the same proprietary mix as the 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, No Tubes recommend visually inspecting Race Day sealant in tires every 2-3 weeks to monitor liquid levels.One litre of Stan's Race Day Tire Sealant will seal up to 16 tyres depending on volume. Cannot be installed through a valve-must be installed directly into the tyre over the bead.FEATURES:Tested and developed with world class athletesRecommended for race day and long-distance event useImproved sealing capabilities compared to Original Tubeless Sealant formula200% more sealing crystal than our Original formula, with added XL-sized crystalsMust be poured directly into tyre, not compatible with injector or other valve install methodsTyre Size: Recommended Sealant Amount:29" x 2.5" 5 oz (148 ml)29" x 2.4" 4 oz (118 ml)29" x 2.3" 4 oz (118 ml)27.5" x 3.0" 7 oz (205 ml)27.5" x 2.5" 5 oz (148 ml)27.5" x 2.4" 4 oz (118 ml)27.5" x 2.3" 4 oz (118 ml)700c x 40 mm 2 oz (59 ml)700c x 38 mm 2 oz (59 ml)700c x 32 mm 2 oz (59 ml)700c x 28 mm 2 oz (59 ml)650b x 48 mm 2 oz (59 ml)
