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, 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.

• Biodegradable fibres and particles bind together with the fast-acting latex to create a clot (like platelets in your blood) to quickly and effectively seal holes and tears up to 6 mm.

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. 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.

Wait, is that plastic glitter?!

• Hell no! No micro-plastics or microfibres here… The platelets in 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 fast acting sealant form an even stronger bond with the rubber in your tyre.
