Peaty's Holeshot Biofibre Tubeless Tyre Sealant - Fast Acting Puncture Repair for Bikes, Seals Up To 6mm Holes, Tubeless Sealant for MTB, Road & Gravel Bike, Biodegradable Sealing Fibres

Been running tubeless for quite a few years now and Stan’s has always been my Go To brand for tyre sealant, but my gripe with Stans is that you can’t (or at least I can’t) inject the fluid through the valve stem after the tyre is in place. This means it can get a little messy pouring the fluid into the tyre then refitting it before blasting the tyre onto the rim which is a pain as you have to seat the tyre in order to make sure it seals properly, then break the tyre bead again, pull on side of the tyre off, pour in the sealant and repeat the seating process again. Not with Peaty’s though. Blow the tyre onto the rim, remove the valve core, pour in the sealant using the handy rubber tube they supply and reinflate. Job done. Haven’t noticed any punctures so it must be doing its job. Easy to clean up as well if you happen to spill….

Peaty’s Holeshot tyre sealant… okay, this is one of those products that’s doing something kind of amazing, and most people don’t even realise it’s happening. So inside your tyre, you’ve got this liquid just… moving around. Quietly. Waiting. And the moment something goes wrong—a puncture, a tear—it reacts. Instantly. It rushes to the problem and seals it. Like a defensive response. Like the system protecting itself. And I think that’s kind of incredible. You’re riding, everything feels normal, and something could have stopped you—but it doesn’t. Because this is in there, doing its job without you even noticing. That’s trust. You’re relying on something you can’t see, and it comes through for you. The consistency is really well judged. Not too thick, not too thin—it flows properly, coats the inside of the tyre, reaches where it needs to go. It’s… adaptive. It responds to the environment inside the tyre in real time. And it handles a lot. Small punctures, thorns, debris—you’d expect issues, but it just… resolves them. Quietly. Efficiently. You keep riding. The system stays intact. There’s also something reassuring about knowing it’s there. Like you’re not alone out on the trail. There’s this layer of protection working with you, keeping things balanced, keeping things moving. And I think people overlook that. They focus on tyres, wheels, pressure—but this? This is part of the ecosystem too. It’s what keeps everything functioning when things don’t go perfectly. Overall: responsive, reliable, and quietly protective. It works in the background, maintaining balance and flow when it matters most. And honestly… I think that’s something worth appreciating.

love the product, but got this delivered without the rubber tube and it's not the first time. I wish they would have a more secure way of keeping the rubber tube attached to the bottle for transportation

Spot on ,used on gazelle bike with road tyres and the small valve so needed to use a syringe to insert the liquid 😉 Spun the wheel up to circulate then inflated and spun for 30minutes Next day the tyre was still fully inflated Brilliant product 120ml was perfect for 2 wheels

Best product on the market, zero flats since using it. Highly recommended

What can I say about this product. I was tubeless virgin, I borrowed a bike a few years ago that was tubeless, it was a royal pain to true and blow up and seal the tyre that had burped on me. Move on 5 years and after purchasing my own bike that is tubeless ready I purchased Peatys on the reccomendation of my brother. Well I could not be any happier, simple tuse, much cleaner than a lot of the competition and in my opinion, it seems to last longer between topups. Which for me as a light user of my bike is brilliant. Nothing more annoying than having to top up everytime I want to go out on the bike. Peaty's solves all of that for me. 10/10

First time moving to tubeless and this was a pain free solution. Big bottle that should last a while. So far appears to work. Not had a big puncture yet but hopeful this will work with Tubless repair kit

I bought this because of the good reviews. I dont know if its possible to have a bad bottle but I used for first time in a brand new GP 5000 s tr tyre. Correct amount put in but first ride I got a small puncture of approx 1mm. The sealant was a waste of time. It ran out of the puncture hole and the tyre completely deflated. Very disappointed!
