This product has been selected to feature in road.cc recommends. That means it's not just scored well, but we think it stands out as special. Go to road.cc recommends
At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Peaty's Holeshot Biofibre Tubeless Tyre Sealant offers impressive performance and longevity, and has good sustainability credentials.
I've been using this tyre sealant exclusively over the last five months. In that time I've reviewed several sets of wheels and tyres for both road and gravel, meaning multiple tyre changes and different setups, and it has always been impressive. I've not had a puncture in any setup where it has been present.
This is a pretty strong indicator of its effectiveness at sealing holes – there is almost no chance that in the same time I wouldn't have got a puncture with inner tubes.
It also has good sustainability credentials, with the main liquid being a water-based latex solution and the biodegradable particles made of cellulose and starches. Despite this, the sealant is nice and thick – I had to shake it extensively just to get everything suspended properly, which is one sign of a good sealant.
I had some 120ml trail pouches of the sealant as well as a 500ml bottle, but while the pouches were good on some valves they were strangely a little too wide for others. In the end I just stuck with the bottle and hose, which was easy to measure out thanks to the marks down the side of the bottle.
At £19.99 for a 500ml bottle (£7.99 for a trail pouch – plus it's available in 1L and 5L bottles) it's good value – Milkit's is a fiver more, and as Stu pointed out in his review, that compared well with options from Challenge and Pirelli.
Overall I have been impressed with this sealant; it's ethically made, effective, and long lasting.
Verdict
Effective sealant that not only plugs holes but also has good sustainability qualities too

Tell us what the product is for and who it's aimed at. What do the manufacturers say about it?
Peaty's says: "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, our 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.
"Our 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."
