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. Using the latest fast-acting latex, our water-based sealant is ammonia-free, non-hazardous and lasts up to 6 months in the tyre in temperate climates*. It won’t ball up in the tyre and is easily washed out. Our biodegradable fibres and particles bind together with the fast-acting latex to create a clot (like platelets in your blood) to quickly & effectively seal holes and tears up to 6mm
What's new?
We’ve been continually testing and refining different sealant formulations since the day we first launched our tubeless sealant in 2017. Over the last few years we’ve worked with everyone from world cup mechanics and every-day riders to professional product testers, testing over 23 different formulations, with countless revisions, to develop a new sealant formula
Biofibres - for a faster, stronger 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.
Thinner formulation - for a faster tubeless setup
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!
Black platelets - less mess
The shiny turquoise bits we had in our original sealant formula can look a bit of a mess stuck to the inside of your tyre carcass - but they did work real well at sealing holes. We tried loads of different shape / size / thickness biodegradable additives to move away from the glitter bits... And tested removing it completely... But ultimately the original size, shape and material always performed the best so we simply changed them to be black to blend in with tyre carcasses and look far less messy if it gets sprayed everywhere.
Wait, is that plastic glitter?!
Hell no! No micro-plastics or microfibres here… the platelets in our sealant are bioglitter made from a special form of cellulose from hardwoods, primarily eucalyptus sourced from responsibly managed and certified plantations operating to pefc™ www.Pefc.Org standards. They work like platelets in your blood, building up behind holes to help our fast acting sealant form an even stronger bond with the rubber in your tyre.
