"Simply put, this is the most effective sealant ... It plugged holes made by a 6mm-diameter screwdriver with minimal fuss, only losing 5 psi from the starting pressure of 30 psi, and holding 30 psi after sealing.

We spent nearly fifteen years working closely with some of cycling's most successful athletes to formulate the ultimate high-performance tyre sealant. Pushing tubeless systems to the absolute limit year after year on the world stage has given us the opportunity to refine and tweak our formula over countless iterations. The result is an exceptionally powerful sealant that has unrivalled reliability when the stakes are high, and everything is on the line.

Our proprietary Race Sealant formula has close to twice the amount of our regular sealing crystals, plus our special XL crystals, which are capable of sealing even larger punctures. Stan's Race Sealant's combination of large and small sealing crystals interlock to form a lattice that not only seals but strengthens and reinforces the area of the puncture, realising an entirely new level of sealing performance. Our latest revised formula resists balling and clumping under even the most extreme conditions, ensuring maximum performance when you need it most.


  • Even more powerful crystals: The new formula is so thick that you can hear the particles just by shaking the bottle. That means even more flat-stopping performance.
  • The quantity and size of crystals in this special formula mean that Stan's Race Sealant can only be installed directly into the tyre. As a result of its immense sealing capabilities, Race Sealant is not compatible with injector or other valve installation methods, as it will instantly plug syringes and valve stems.
  • Just shake and pour - While the new formula is too thick to inject through valve stems, you no longer need to completely invert the bottle when pouring it, because the latest crystals are capable of floating.
  • Race sealant is a high-performance product that should be inspected every three weeks for best performance. A quick shake of the tyre will help you know where things are at - if you can hear it sloshing around, you should be good for a while yet. How long an application will last will depend on factors such as tyre choice and the environment you live in, although Race Sealant is able to last for months following installation under many conditions.
  • Be sure to rinse Race Sealant out of used tyres intended to be stored/reinstalled.


  • Race Sealant's instant sealing power and high strength make it the best choice for road/gravel applications, where the higher inflation pressures often overwhelm other types of sealant.


  • Race Sealant can be mixed with regular Stan's Sealant in whatever ratios you like.
  • Need to top up a tyre that's set up with Race Sealant? You can quickly inject regular Stan's through your valve stem to keep your tubeless system up and running.
