Orange Seal Endurance Formula Bicycle Tire Sealant for Road, Mountain Bike, CX, BMX, and Tri Bikes (8oz)

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.

Fat bike

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.

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

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.

Works like its suppose to and at a really good price. This one does not have the tube for dispensing fyi. So you will need some small tubing in order to get the fluid into the tire through the valve stem.

Used this on a tire that would not seal even though the bead was set. This was NOT a tubeless tire, but rather a wire bead tire. When I tried the strap around the tire trick to force a seal it wouldnt take. I thought, what the heck, let me try the sealant. Did the same trick and literally saw sealant seeping out of multiple rim/tire interfaces on both sides of the tire. I kept pumping for a few minutes and suddenly it started to inflate. I removed the strap and successfully got the tire up to pressure. After cleaning off the sealant mess I decided to test it out. I went down to a low pressure (tire rated 30PSI min, I did 15PSI) and took the bike on a tough gravel hill climb. It did excellently and the pressure was the same after the ride! Unfortunately I tried to add more sealant and couldnt get the seal to stick this time. Perhaps I kinked the wire bead. Dunno. But I was convinced that if this sealant could seal a tire with that much leaking air AND handle a rough ride on a NON tubeless tire set up for tubeless, then it should do great on a real tubeless tire. Best of luck to you

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.

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.
