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, it is recommended to visually inspect 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. Cannot be installed through a valve – must be installed directly into the tyre over the bead.
