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.
