Developed alongside World Cup mechanics and world champion racers. Peaty’s Holeshot Tubeless Sealant is packed full of biodegradable fibres & sealing particles to give a fast and strong seal.

The biggest change with the holeshot sealant is the addition of biofibres. Fibres tangle up with particles and latex to create a faster, more durable seal. Our original sealant didn’t have any fibres. This is because the most common - and easiest - way of achieving a fast seal is by using microplastic fibres. These are very cheap and easy to get hold of, but they’re terrible for the environment, so we stayed away from them. It’s taken us years to find a biodegradable fibre that seals holes well, yet also lasts a long time in the tyre. To get a good seal you need fibres of a really specific size, so after years of testing and development we’ve finally found a fibre which gives incredible sealing performance, while remaining super durable.

We’ve also made the sealant slightly thinner, for easier initial setup, and added higher concentrations of sealing compounds - to work with the fibres and platelets and give a better / more durable seal. That sounds easy right, just add more sealing stuff yeah? The problem is, the more sealing ‘stuff’ you add, the less room there is for other ingredients. Adding more of one thing then throws out the balance of other ingredients, so the more unstable it becomes. Perfecting a sealant which flows easily, seals quickly, works in a good range of operating temperatures and remains super durable has been a long and arduous journey. But we’ve finally got there!
