    Ive been running this sealant with my Mavic Comete tubless setup since the begenning of the season. Ive had several small punctures that have sealed almost instantly with virtually no pressure loss as well as a larger (thumb tack size) puncture. The larger puncture sealed fully within about a minute of fast riding while losing about 20 PSI. This was right before a rain storm and I was glad to be able to keep going rather than stop and change a flat during a downpour.

    Just broke the bead on my tires for the first time since going tubeless in early April. To be fair, this is my 1st time trying tubeless, Id avoided it due to concerns about it being a mess to swap tires... I also didnt get (that I could see anyway) any punctures to really test it out, but then Ive never gotten many flats anyway, part of why I never saw the need to go tubeless. My rear tire had a film of latex (I guess its latex?) but did still have liquid, maybe an ounce or so. The front lacked any film, and only had maybe half an ounce of watery orange liquid... thats probably on me. Interestingly enough, I noticed the rear losing air more so than the front, but that could be due to my narrower rear tire and the higher PSI I keep it at. Either way, both tires stayed rideable for at least a week between top-offs. Cleaning the dried film out of my rear tire was pretty quick & painless, other than right on the beads it peeled off in huge sheets. So while I cant vouch for its puncture sealing abilities, it does a good job of keeping tires airtight otherwise, and seems like the 6+ month lifespan is right on. Which is what I was more concerned about anyway, personally... I didnt want dismount, clean, and reseal tires to be something I did a couple times a season. I killed what was left of my original 8oz bottle on this use, and have a 2nd on the way so I can add a little more and have some on hand. While I never really had major issues with tubes, this stuff is convenient enough that I had no thoughts of going back.

    Been using Stans race day almost exclusively in (700x28 GP5000 70psi) as it is the only thing that seems to actually work, but tried this in the hope that it would laster longer than the 4 weeks of the Stans. It lasts longer but just doesnt seal most of the time, I dont get it, everybody raves about the long life, but if it cant fix the hole like ever, then it really doesnt matter how long it lasts.

    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

    After reading about different tubeless tire sealants I decided on Orange sealant. A lot of sealants react to C02, but not this one. I already had about 4 punctures and it sealed everyone of them. Excellent choice.

    Perhaps its too early for five stars, since Ive only gone tubeless on my mountain bike for about a month. But this stuff really works for me. I ride on a trail with lots of gravel, sharp rocks and fallen branches. After sealing punctures on both my front and back tires, i pump up the 29x3 tires to 30psi and they just keep rolling.

    This is what Ive used on the Great Divide Mountain Bike Route and never had a flat. I guess another sealant could have worked but I know this one did work. It tests well in reviews and I trust it.
