    Ever since I switched to tubeless tire, I have had numerous tire punctures (maybe 10?). 9 of out the 10 times, it just sealed itself without me doing anything other than getting off the bike and spin the tire for couple of mins. It does got messy when the sealant sprayed everywhere but it is also beautiful that it usually stops after a few mins. I use the Orange sealant exclusively. I think the recommendation is to change it every quarter, but I found that I can stretch it to 9 months and the sealant is still ok.

    It is a good sealant on road bike wheels. I was using stans on MTB for years without any problem. When the tubeless trends on roadies I add stans as well but it seems not good at all. Then I purchased this orange sealant and the flat problem never stopped me again. I will recommend this one.

    I use it in my tubeless gravel bike. Has saved me on multiple occasions. I even had a cut in the sidewall of a tire that sealed and lasted about 500 miles. Only reason it didn’t last longer is I replaced the tires because they were bald

    It was really easy to clean this out of tires, making tire replacement really easy. The sealend works amazing and lasts long aswell

    Definitely works well and holds air like a champ. I would highly recommend the Sealant to anybody looking for something durable and for us free. Change about every 60 days and you’re good to go.

    Setting up tubeless tires can be messy. This stuff is great in that context. Its easy to clean up, easy to use and is eco-friendly.

    I had a tire that didnt look worn. Only had 400 miles of use. But Id run out of Stans Race Sealant, so I mounted it with regular Stans because thats what I had on hand. And at 400 miles, that thing turned into a sealant sprinkler. Innumerable tiny holes would spray sealant all over on my commute, then seem to seal -- only to start spraying again next time I tried to ride. After a few days of that, and topping off with more Stans, I thought I was going to have to replace the tire even though it didnt look worn. I still hadnt been able to get Stans Race at any reasonable price, though, so I ordered a bottle of this stuff hoping to actually get a lasting seal on those pinholes. It worked. Ive got 900 miles on that tire now and it hasnt shown any sign those pinholes exist, or of any other trouble, since I first added this sealant to the tire.

    This sealant is easy to install and is not as gloopy or smelly as some others I use in road and MTB tires.

    Use a third less than recommended. My 29x3.0 tires only needed around half. Seals instantly, 1400 trail miles and no flats.
