NoTubes Race Day Tubeless Tyre Sealant

Developed with world-class athletes and their mechanics, the Stans Race Day Tubeless Tyre 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. The Race sealant is better performing than the regular but you may need to top it up or refresh it more frequently.

We like this when you want increased confidence in your sealant, be that for a race weekend or a week in the Alps. Otherwise we tend to recommend the regular Stans sealant for normal use as it lasts longer in the tyre. 

One litre of Stan’s 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.
