Peaty's Tubeless Sealant

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 & 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 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!

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.

Does it perform?
The reviews speak for themselves. Peaty's Holeshot Biofibre Tubeless Sealant has been awarded a perfect 5/5 stars from world renowned product tester Guy Kesteven over on BikePerfect.com.

Setup instructions
Shake the bottle vigorously before every use to ensure an even distribution of fibres and particles.
Rinse away any old sealant from the tyre and dry off completely. For brand new tyres degrease, rinse and dry the internal carcass to remove factory mold release agents and other contaminants.
Seat your tyre onto the rim and inflate initially with no sealant, using a track pump, inflator or compressor to pop the tyre bead fully onto the rim.
Deflate the tyre and, with the valve at the three o’clock position, use the flexible injector pipe provided to inject the desired amount of sealant directly through the de-cored valve.
Re-insert the valve core and re-inflate the tyre to desired pressure.
Distribute the sealant around inside the tyre by spinning the wheel and tapping the tyre on the floor.
Listen for any air leaks and orientate the wheel so that the sealant flows around the inside of the tyre to the area required. Continue doing this until you can’t hear any more air loss †
Wash away any excess sealant that may have found its way to the outside of the tyre or rim with water.
Check tyre pressures and ride!
If a seal can’t be made, add more sealant in increments as required
