Peaty's Holeshot Biofibre Tubeless Tyre Sealant, Fast Acting Puncture Repair, Seals Up to 6mm holes for MTB, Road and Gravel Bikes, Uses Biodegradable Sealing Fibres

As with all of peaty's products, this works extremely well. I've only had one puncture that it was unable to seal permanently, but even that was still restricted to slow puncture (dropping by a couple of PSI per hour).I've also not had issues with valves clogging.

Great sealant. Used many types over the years but this seems to work well. Just having Steve Peat behind the product sits well with me. Top downhill champion now selling Ggreat products👍👍👌

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….

Just a shame that it only lasts in the tire for 6 months. It said it on the bottle but I only saw it once it arrived

I have always used Stans fluid in the past but thought that I would give this a go on a set of new gravel tyres.First ride in and a puncture in the side wall. Sealed almost instantly with minimal loss of fluid. So far so good.

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

Very good, does what it says on the pack

Initially thought Peaty's was great for my road bike as it the tyres held pressure much longer than with Stans. However when I did actually get a puncture it would not seal properly and blew out every time it was pumped back up. Pumped it up to only 40psi and it held for a bit, so I thought it was sealed. Topped up with more sealant for the next ride but it blew out again and would not hold this time. The hole was <2mm and too small for a plug. Had to put in a tube - Very messy and ruined the matt finish on my carbon wheels! Cue Muc off sealant remover and a lot of scrubbing but the wheel will never be the same! This stuff is thicker than Stan's and much harder to clean off.Have lost faith in tubeless now and considering going to TPU tubes for the road bike.
