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

Works great

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. :)

The product gets a 5 Star rating, absolutely the best you can buy! But, be careful of the seller. I received my Orange Seal Endurance on October 5, 2021. The expiration date on the bottle is July 19, 2021. :-(

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

Over the last 10 years Ive tried dozens of different brands of tubeless tire sealants, including the most popular S brand, as well as others and I will say that the best sealing, easy-to-work-with, long-lasting sealant of the bunch is Orangeseal. You wont find any gimmicks here like rainbow sparkle flakes or UV glow - Orangeseal is just a sealant that works. I put 2 ounces in each 27.5 tire of my mountain bike, and that usually lasts about half a year before I notice the sealant level drop (I check the level once a month). When I have to swap tires, the old sealant is simply a layer of coating along the inside of the tire - it doesnt clump up into chunks, and it doesnt create messy spiderwebs of dry sealant that takes hours to clean up (unlike the most common S brand). Ever since I switched to Orangseal, I cant remember the last time I had a real flat tire. This is the good stuff, for sure!

Worked well! Old sealant was dry, just added 4oz in each tire. Will buy again

This sealant is useless. Send it back to the orange julius store. Figured I would try it since it is a little cheaper than Stans but back to Stans it is.

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

This is the best sealant for for east coast riding.
