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

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

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

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

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.

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….

Excellent product

Works well on tubeless set up similar to muc off

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.
