Un très bon préventif
Impeccable, le Muc off fonctionne très bien pour les crevaison. Je l'utilise pour mon vélo de route et un petit avantage, avec une lumière violette vous pouvez savoir ou vous avez crevé.

Good tubeless road tire sealant
I’ve tried all the popular sealants and this one is the best for the higher pressures of road bike tires. You and your bike don’t get sprayed, seals really fast. Super easy to clean, just scrape it out with a spoon and hot water. Usually lasts about 5 months. And of course it works great for MTB tires.

Easy and amazing sealant.
Great sealant other than the color. Total joke. Works amazing. Great value for the money. Like all sealants just don’t make a mess and it’s not messy. Good thickness. It saved me on my rim tape leaking long story but I prefer muc off rim tape now. I suggest 20 more ml than you think you need. It’s worth it.

Works great; measurement system leaves something to be desired
This stuff is great. I've tried a few different brands, but came back to this one for my road bike tubeless setup. It works well and does the job. My first flat with this stuff was caused by a 1/8" (3-4mm) gash in my sidewall after a lot of use. The product claims to be able to seal that sort of thing, but there's not much hope as there's just not enough sealant to slosh onto the sidewall from the tread area where it naturally collects. This product does recommend using varying amounts of sealant based on the size of tire (tyre) or terrain. They provide a little window in the bag for measurement of the amount dispensed, but it's totally useless. Instead, I would have rather they printed the density of the product (e.g. g/ml) or provided measurements in grams allowing me to use a scale for measurement instead.
