Make flats a thing of the past.
Stans NoTubes Tire Sealant uses proven "sealing crystals" to repair small punctures and larger cuts. The low viscosity formula allows it to coat the entire inside of your tire for effective protection, wherever you need it.
Two ounces is all you need to seal most road or MTB tubeless tires. Stans Sealant can also be added to any inner tube or tubular tire with a removable valve core. The sealant stays liquid for 2-7 months, and is non-hazardous, non-toxic and safe for the environment.
32 ounce bottle (up to eight applications).

I have been using Stans-no-tubes for years. I have tried others, and keep on coming back to Stans. I do not care for the "race sealant" version, since it clogs valves and does not work with a sealant injector.
With spring approaching itï¿½s time for me to start getting my bikes ready for the new riding season. Although my tubeless tires are holding air, that doesnï¿½t mean they are ready for the new season. Part of my spring maintenance routine is to dismount my tubeless tires, clean out the old and dried sealant, remount the tires and refill them with fresh Stans sealant. That way I know that my tires will function as expected if I get a puncture. I've found that I can alway depend on Stans.
I am new to tubeless road tires. I ran tubular tires since the early 70s. Since switching to tubeless I have had two incidents. The first incident was a shredded tire and nothing could have saved it. The second incident Stan's sealed almost instantly and continued on my ride without a second thought.
I've used tubeless for road, cx and mtb for many years now. The sealant has sealed countless flats. Tubeless can be a pain to set up and but once dialed in it's great-often, but not always, seals punctures, can prevent catastrophic fails, and improved ride quality are all pluses. Stan's used to be the only name in the game but now there are many alternatives. Some wheel manufacturers (Shimano) void their warranty if you use Stan's due to a small amount of ammonia in it and worries about nipple corrosion. Stan's disputes this and I have never had a problem. Between Stan's and Orange Seal Stan's seems to dry out faster but I have had Orange Seal fail due to the latex drying out but there still being plenty of whatever the liquid base is. That said, I use both since my LBS stopped carrying Stan's-I bought some through this site. And they're both pretty pricey, but worth it overall in my opinion.
I'm new to no tube tires. Stan's No Tubes products came highly recommended by all my fellow riders. This has been my product of choice over the last year for a road bike and mountain bike setup. No flats, no complaints. It's my understanding to add 2oz's every year to each tire to keep tires trouble free. So far so good. I recommend.
Purchased Stan's sealant when I started riding my road bike with tubeless tires. The sealant works. I haven't had to repair a flat tire in 4 years. I also use Stan's sealant in my cyclocross tires. How do I know it works? Occasionally I will have a puncture and I will hear air leaking and notices a small amount of sealant exiting the puncture hole. After a few revolutions the puncture is sealed, and I keep on riding. I regularly pull goat head thorns out of my cyclocross tires and watch the sealant fill the holes while a small amount of air escapes. The sealant does evaporate so you need to add more sealant, frequency depends on temp and humidity. One thing to be aware of, most of the sealant is liquid with lots of particulate suspended in the liquid. I think the particulate is what actually fills the puncture holes. When you get to the bottom of a bottle of sealant there is usually not much particulate left. At that point your better off not using the remaining sealant. Best to start a new bottle with more particulate. Check out Stan's No Tubes web site on for useful tips on going tubeless and using the sealant.
I don't recall the name of the first sealant I used, so I bought this sealant based on price and recommendation of a friend. I am very happy with it. I used for some 650b tires on new wheels. Initially I put my "normal" amount in, but noticed that I was losing more air than i usually would. Put in 2 extra ounces and now sealed great.
On sale, the price was good, but I think you still pay for "Stan's" name, I do recommend this, as long as you can get it on sale.
Had my first puncture last week on my Conti 5000 TL. Happened about a mile into my ride. I stopped, gave the tire a quick spin, put my finger over the puncture to give it time to seal, and after a minute, I was on my way. I lost about 10 psi but felt no need to top off the air. The cut was a little jagged, maybe a couple millimeters or a 16th of an inch, so I'm thinking a small piece of glass, but the air and sealant blew it out so don't really know what it was. All I know is I stopped but for a minute and was soon on my way.
