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 in 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, Stan's recommends visually inspecting Race Day sealant in tyres every 2-3 weeks to monitor liquid levels.

One litre of Stans Race Day Tyre Sealant will seal up to 16 tyres, consult their sealant volume charts for more detailed guidance. Cannot be installed through a valvemust be installed directly into the tyre over the bead.
