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 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
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.
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.
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?
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.
I hardly even check my sealant, I just carry a 2oz bottle and if I spring a leak on the trail shoot up and keep rolling. This plus co2 of course, to reseat the bead if needed.
Then I can actually refill the little bottle and use saran wrap to create a good seal for next time.
At first, I balked at buying single-shot sealant. However, the small bottles are great if you have to re-seal tires during travel and don't want to pack a jug of sealant. Also, this packaging gives you the right dose for a single tire with the right amount of sealant particles in each dose...BTW, the stuff works. One of my tires (Schwalbe Rocket Ron) recently took a beating on rocky terrain. The sealant plugged several small holes so well that I didn't even notice the damage until I spotted little patches of sealant mixed with dirt stuck to the outside of the tread. Any ride where I don't have to waste time futzing with flats is a good ride.
I've been riding with Stans NoTubes on my road bike with latex tubes for several months, and have had no flats. I did have a puncture - the dreaded hiss - and looked down to see the white Stan's latex squirting out, and thought it had failed. But a few seconds later it worked its magic, sealed up, and I had enough air pressure remaining that I didn't need to stop, and wasn't dropped by my fast group ride.
