The release of Peaty's original sealant didn't mean that the brand's engineers could sit back and relax. Instead, it was right back to the drawing board to refine a range of sealant formulations having tested over 23 different formulas to develop the new Holeshot Biofibre Tubeless Tyre Sealant.
The most notable new feature found within the sealant is that it now uses fibres that are included to entangle and intertwine with the particles and latex to seal punctures quicker while creating a more reliable seal. The reason why this wasn't included in Peaty's original sealant is that plastic microfibres are pretty bad for the environment and the designers couldn't find a biodegradable alternative that works well and lasts long enough in the tyre, until now.
Along with the biodegradable fibres, Holeshot sealant is also thinner which is said tomake initial setup easier by coating the inside of the tyre quicker. The brand says that it still 'clings' to the interior too.
The Holeshot sealant features a higher concentration of sealing compounds to work with the fibres and particles with the aim of creating a more durable seal. Speaking of particles, they're now all black so if the task of seating tubeless tyres did get messy, there wouldn't be shiny blue bits of glitter everywhere.

It's not all about the new sealant as Peaty's has launched the Holeshot Tubeless Conversion Kit alongside. This comes with everything you'll need to convert your tyres to a tubeless setup, including tape, the brand's MK2 valves and the new sealant. This is available in four kinds developed for road/gravel bikes, xc/trail, DH/enduro and dh/wide, all coming with the correct amount of sealant, the right width of tape and length valve. There are also links inside of the biodegradable packing with full installation instructions hosted by Steve Pete himself.
Prices for the sealant start at £8 for the 120ml trail pouch with 500ml costing £20 and a litre, £30. This is also available in 25L bottles that'll set you back £500. As for the Holeshot Tubeless Conversion Kit, prices start at £45 for the road/gravel kit and go up to £50 for the rest.
