Stans NoTubesTire Sealant 16oz(Return to Product Page)

Stans Sealant just works. I have used it on road, gravel, and mountain bikes, all tubeless. On road with tubes I would get two or three punctures on a single ride. After switching to tubeless and using Stans, I rode over 1700 miles without a flat. The only issue I ever had was recently with one set of Maxxis Velocita tires where (quite a few) goat head thorns would puncture but break off and stay in the tire, leaking slower than what is needed to activate the sealant. Stans even worked for a ghetto tubeless conversion on an older (non-tubeless wheels and tires) mountain bike.

Stans NoTubes is a kickass company. Quality products just like this sealant. It's a classic.

I had waited too long to add sealant to my tires but had everything purchased when I picked up a nail on a ride. I noticed the nail when I got home but waited to remove the nail until I was ready to add sealant. Since the old sealant was dried up, the tire immediately went flat when the nail was pulled. Once sealant was added and the tire was pumped up, the sealant filled the hole within a minute. The hole was almost large enough to require a plug, but the sealant stopped the leak!

What can you say? Stan's is great - seals my gravel tires nicely. Usual great price and service from biketiresdirect.

Works great! Fill the tire once and it's good for, well almost forever, or at lest the lifetime of the tire.

I regularly ride areas with a basketful of hazards, thorny cholla balls being most prevalent, and all I do when I get home is break off the spikes at tire level and leave them in the tire.

I just replaced a tire I wore the tread off and it still had the original fill of Stans doing it's job. When I took the tire off, the inside looked like a forest of spikes, made up of all the spikes picked up in the lifetime of the tire.

Way to go Stans!

I recently replaced my tubeless tire for the first time and so its the first time I have ever used tire sealant in this application. That being said, I have already tested it and it works great. I broke the sidewall of the tire while hopping up a sharp lip. I was devistated at first but when the 316 gap started to seal up I was super impressed. I thought such a large slice would surely be unrepairable but this sealant closed it right up and I have been riding on that tire ever since. Long story long, I highly recommend this product because it works

I use it for my tubeless tires and it works just fine. I have used it in the past with good success. I will use it again.

Tubeless road is amazing. Stan's makes it that way.

Stans NoTubes Sealant! It just works as it is prescribed. Follow their direction and get the protection!

Best thing I did to completely stop goat head flats.

Seals small holes and is easy to add after removal of the valve core. I've had practically no spillage.

I've used Stans on my tubeless mountain bike tires for a number of years. I've never knowingly had a puncture and certainly not a flat, while many people riding with me have had numerous flats (very annoying slowing down the ride like that). Well maybe I'm lucky and maybe its the Stans. Certainly easy to use. With UTC tires I would seldom have to add air. A little more frequently with TR tires.

First time using tubeless on cross bike, holds pressue great. After installation no lose of pressure, went a week before i had to top off.

Installation was pretty easy. Works good so far.

Converting my tires to tubeless was a breeze. Stan's tire sealant is reliable and lasts a long time.

Used for sealing both Road and MTB tires no problems

I put about 2 oz. in my 23mm road tire. So far I have not had to plug a leak.

Stan's works really well in the tubeless tires....make sure you put enough in as it eventually does get dry. Definitely helps if you get a puncture!

Used Stans for years. Great stuff. Lots of miles and lots of trails. Works very well.

Works very well seals holes very quick. Don't have to put air in tires as much on road bike or mtb.
