Muc-Off Road & Gravel Tubeless Tire Sealant | High-Pressure Puncture Sealant for Road & Gravel Bikes | Seals Holes up to 7mm | Works Up to 110 PSI

First time going tubeless and the 140mL package was perfect for the job. It was enough to fill both tires (700x28), and I immediately saw the sealant working. While prepping to add the sealant, I noticed couple holes leaking air when I first filled the tire to set the clinchers. I removed the valve core, added the sealant, put the valve core back and refilled with air. Gave the wheel a good shake and voila, no leak! Did not notice any of the sealant liquid coming out of the holes, let alone air!

What can I say, this is my brand. Tried and used many others, but this is the one..

Had an inner valve stem leak, that I didn't have time to take it to a tire shop. This sealed the inner valve stem leak I had. Works very well and a durable fix. Easy to use but must use an install tube makes it easier to pour into valve stem and must remove the inner valve stem core. It's an okay value for the money.

It's a new formula and it works to seal small holes quickly. I originally used Stan's which didn't work at all with road bike pressures. This Muc-Off sealed in seconds, but also struggled on every subsequent ride with pressures over 65psi on a relatively small hole. Searching for something that works better on road pressures .....

Excelente

I love caring these with me on rides as peace of mind if I'm unsure when I last filled my tires with sealant. Just make sure to remember it's sealant and not a gel!

Versatile product

Extremely easy to put sealant into tires without extra equipment.

Easy to use.

I’ve been using Muc Off No Puncture Hassle on my road bike for a few weeks now and it’s already saved me from at least two flats. It seals small punctures almost instantly and I barely even noticed I had one until I checked the tyre later. The sealant is really easy to use and is long lasting and the instructions are clear. I used it with standard inner tubes and it went in smoothly with no mess. It doesn’t dry out quickly either, which is great for longer rides or when the bike is stored for a while. What I love most is the peace of mind it gives me. I ride daily and hate having to deal with punctures, but this has made a huge difference. The bottle design makes it simple to use and there’s plenty of product for multiple applications. Overall it’s a brilliant bit of kit that does exactly what it promises and at great value. I’d definitely recommend it to anyone who rides road or gravel and wants to spend more time cycling and less time fixing tyres.

super efficacité

I wanted to try this I'm not disappointed but it is a little spendy that is for sure. Hechas feliz American see you to the other brighter what I found with some the products is it a rives and Frozen and the Summer season and that to think recogman by the stuff make sure that you bring it When the temperature outside is the nice for some reason last one direction was chunky and disgusting It's Frozen but some point and that key. Ejecting it is very similar the tip will work on a Schrader valve but it doesn't work with the press that you do have to use an injector or pull the tire off the rim that's not my preference it's a pain in the butt so it's just easier to pull the valve stem and inject it but I say to each their own I don't like putting too much in there but overall I like the size of this package cuz I can throw it in my bike bag and gear when we go riding but there's basically enough to do two tires at best.

Ma roue avant de gravel perdait de l'air entre la jante et le pneu seulement 8 mois après l'achat du vélo (de 2,5 bar à 0 en une demi-journée...). Je suis donc allé interroger le vendeur qui m'a dit qu'il fallait remettre du préventif tous les 3-4 mois, ce que j'ignorais. J'ai rechargé avec ce préventif après avoir vu ses éloges sur des vidéos en ligne et sur des commentaires très positifs sur Amazon et sur des sites spécialisés, mais je doutais fortement que cela puisse résoudre les fuites vu leur emplacement. Cette bouteille de 1 litre est livrée avec un tuyau d'une vingtaine de centimètres à insérer entre la bouteille de préventif et la valve, mais j'ai préféré utiliser un kit avec seringue acheté en parallèle, afin de faire la manipulation proprement et sans en mettre partout, et pour faire un dosage précis. N'ayant jamais fait de charge en préventif, j'ai été très soulagé et satisfait : - De trouver sur la bouteille le mode opératoire et une indication sur le volume de liquide à ajouter en fonction des dimensions du pneu (60 à 80 ml environ dans mon cas), - De voir que la bouteille dispose d'une ligne translucide graduée permettant de savoir à peu près quel volume on injecte et combien il reste de préventif dans la bouteille, - De constater que la bouteille peut se recharger. Une fois le volume souhaité dans le pneu, j'ai fait tourner la roue sur elle même à l'horizontale, d'un côté puis de l'autre, et verticalement. J'ai eu la très agréable surprise de constater que mon problème de fuites a été résolu. Ce préventif est donné pour colmater des trous d'environ 6 à 7 mm et je suis certain qu'il fait le boulot d'après ce que j'en ai lu. Je pourrai mettre ici un avis plus éclairé quand j'aurai parcouru quelques centaines de kilomètres avec !
