Unless you have an obvious puncture and see sealant spray and stop is it really Working? I hope not to find out. I have had thorn, tacks and road ash flats in the past. When I set up new tires I installed Muc-off no hassle inner tube sealant. I have aprox 1500 miles on the tires and no flats. I have had some gashes that I found on inspection but no leaks.It takes a little patience to install the sealant through Presta valve stem. Just follow directions and go slow. Valve core must be removed. I will use this product in my other tube setups.

Some might say it's not ideal to carry a few ounces in case of a puncture, but it has helped me. Add a few ounces to a flat and save yourself the tire change until you get home...or maybe not at all. Works well for tubes and tubeless.

TLDR; Working with Presta? Get an injector.Sealant worked well with my own injector, but the tube it comes with wouldn't seal onto my inner tube's valve steam. Feels like it is meant for Schrader rather than Presta, but I haven't checked. Didn't see an adapter in my box. If it lasts as long as they claim I'll update to a 5 star.

Much Off Sealant doesn't work on inner tubes... Pinhole punctures would not seal. I removed the tube and no pink sealant had gone to the puncture. Figured I'd use the rest of the bottle and go tubeless again. It wouldn't run to the bead of the tire like, Stan's or Caffee latex. I needed to manually coat the whole bead with it. Time will tell if I actually have a seal. Stan's does oxidize aluminum rims which is why I stopped using it and started with tubes again. That said it does the job. I actually ate a hole in some road wheels. That being said I'm guessing some oxidation may also occur by the nature of air against the rim. Tubes don't allow air and moisture to contact the rim. I now ride in an area with lots of cat brier so Stans and tubeless is my only alternative to numerous flats. If I ever switch to carbon (no oxidation) road or mountain tubeless and Stans are a no brainer.

I know this is advertised as an inner tube sealant. (I should have double checked before I purchased, but I thought I'd give it a go with my tubeless setup with my hyper scooter). Holy heck. Not only did it seal a flat I had, but a week or two later, someone deviously rammed a 2" long nail into my tire while it was locked up outside and it didn't go flat until I removed the nail a couple miles down the road. Very impressed.

Das Zeug ist echt gut. Hoffe ich zumindest :-D. Das Einfüllen ist keine große Baustelle. Im Karton liegt neben der Flasche auch gleich ein Ventilschlüssel aus Plastik und zwei Dichtungsringe mit bei. Einfach den Reifen plätten, das Ventil herausschrauben und den Dichtungsring über den Rest vom Ventil stülpen. Dann den Rüssel aus der Flasche ziehen. Ich habe den bei mir einmal leicht eingeknickt. So hatte ich einen besseren Winkel und konnte das andere Ende fester gegen den Dichtungsring am Ventil pressen. Ohne das Knicken ist erst mal ein bisschen daneben gelaufen. ICH würde dem Hersteller ja vorschlagen, den Schlauch etwas flexibler zu machen. Das Ding ist einen tacken zu starr. Aber das ist nicht meinem Baustelle. Es war bei mir genug Flüssigkeit für 3 Reifen in der Flasche. Je 100ml. Also musss ich doch noch eine Flasche nachkaufen für den zweiten Reifen am zweiten Bike. Ein Schelm wer hier böses denkt ;-). Aber wir sind ja generell alle sehr zufrieden mit den Muc Off Sachen. Gute Arbeit macht ihr!

I only topped up existing fluid in tyre as was leaking air. Used 70-100mm and worked perfectly. This was in tubeless bicycle tyreI did spin tyre and did this every few minutesDown side is the straw is not flexible and leaked a little but not much.

I purchased my first 'Tubeless' kit from a Magical place in Chorley. I was apprehensive at first as the reviews of Muck-Off were crapI purchased this top up item because I found Muck-Off not to be crap I installed tubeless to my rear wheel only around Jan 2024 so needed a 'maintenance' productSorry for the waffle but during October '23 through Jan '24 I had 3 punctured a week. I installed the tubeless to rear only and I've never looked at my oily palms again.Now you may question why am I leaving a review for a product bought elsewhere. The reason is because when purchased this item I was expecting to have use of frequently.The YT videos aren't always correct. The product works for me. I've never had a slash in a tyre. Only hedgerow.All's good.P.S. Thank you for reading. I only put a p.s. on to see if you gave continued to read ..ðŸ‘😂

Je ne saurais jamais totalment si ça fonctionne ou pas, car j'ai mis en prévention; mais de toutes façons pour mon VAE je voulais faire tout de mon possible pour éviter les pneus crevés.Je conseil le produit.
