Works ok and is better than Finish line sealant. Could be better. But if you want to convert to tubeless it will work. I used it with a set of Panaracer Gravel King SK's and DT Swiss C1800's. It seemed to hold up well until I took it off road and then it decided to start leaking for some unknown reason. I could not identify any punctures or any apparent reason for the leak. So maybe it was just a bad match of tire/rim. I just don't know. But it does work for seating a tubeless tire and does hold air over decent periods of time. So it might be worth trying to see if you have better luck than I did.
I've discovered that a little bottle of sealant is de rigueur for your trail kit while bikepacking, that's why I got this. I'm sure it'll work fine. This one is the smallest I've seen. Orange seal has one with a better install system but the bottle is not as small. I've been told that white-colored sealants will play nice with other white-colored sealants.
Injecting Stans Tire Sealant into presta valves tubes using 2 oz plastic bottle is complete disaster and doesn't work. You cannot put the bottle nozzle on top of the Presta valve opening and expect to inject the sealant without half the bottle of fluid running everywhere else except in the tube!. To successfully make it work.. buy the Sealant Injector for another $9.95.
I had the misfortune of having three flats in two weeks. I normally get one a year. I initially blamed my new wherlset - I was frustrated after using oodles of glue - I ride tubulars. I tried many competitor products after the puncture occurred. Stan's no tube worked amazing not only sealing hole but fixing the hole - I have since clocked 2 months without an issue - my tubular has a latex inner tube so perhaps the best combo. I since placed Stan's prophylactically in both tubulars - front and back. I ride 300-400 km wk
I've been running tubeless on my mountain bike for a few years now and I haven't had a flat or issue. You can run low pressures that would normally guarantee a flat with tubes, but not cause any issues with tubeless. When the tire starts to run low after sitting for a few days (like mine did) you squirt it thru the valve stem with the handy dandy top of the container and voila your back in the game.
Kinda expensive. But it works. It's not really something one would review in a WOW, THIS IS GREAT sort of way, now is it? So. Put it in your tubeless tires, and most of the time it will seal a puncture. Sometimes it will not. If you think it will seal every puncture, your expectations are unrealistic. But that's not the product's fault. Nuff said?
Works on punctures and cuts less than 1 mm.
Works better on puntures compare to cuts.
Borderline on 1-2 mm cuts. May be ok for same size (1-2 mm puncture)
Does not work on cuts more than 2 mm. 2mm cut under pressure it will fail.
You can wipe out the liquid easily if you make a mess. even without water. Doesn't stick or leave stain on your cloth after washing.
I recommend this product because if you can't fix the flat with this you won't be able to fix it with Vittoria pit stop either. Yet Stans is alot cheaper.
I wrote a comment on Vittoria pit stop if you are interested.
I had bought Tufo sealant also but have not tried it yet.
If you have multiple sets of tubless wheels, or frequently refresh your sealant, the large jug of Stan's sealant is more economical and eco-friendly. However, these little 2 oz shots are good to carry on travel for backup, or while riding for emergency repairs. You can also re-use the bottles to ensure you're adding consistent doses of sealant from the big jug to your tires. With higher volume tires (e.g., 29 x 2.2-2.4), I need 3-4 oz for a good initial tubeless seal. For lower volume road tires, one 2 oz bottle per tire should suffice.
This is the perfect amount to turn one wheel into tubeless. The big bottles typically dry up before you can use it all, unless you work in a shop or are setting up a bunch of bikes with tubeless. You need a tubeless capable tire and rim. I have run tubeless from the first year mavic came out with UST. Back then stans' wasn't a good product, now it is great. Running this with my UST rim strip and UST capable tires saves tire weight (good place to save weight on a bike) and still allows me to run 25psi on my 2.4/2.2 tires. I had a thorn on my second ride using this and sealed up and I didn't have to throw away a brand new tire.
If running tubeless this is definitely the way to now
Stans is a brand you can trust. Their sealant bottles fit easy into a valve core. Just remember to refresh the sealant 2-3 times a year. I use these small bottles when I travel with my cross bike for backup.
