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

This is the best sealant for for east coast riding.

I love this stuff. Lasted almost a year on my Giant TRX1 wheelset with Schwalbe Nobby Nics front and rear. I dont know if Ive had a puncture yet so I cant comment on that. Its also the only sealant Ive used so take this review with a grain of salt. :)

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.

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

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.

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.

Best

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

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.
