Trail Proven Reliability, No More Pinch Flats

- Reviewed in the United States on January 18, 2021Size: 16-OunceVerified PurchaseIf you go to your local bike shop and ask if you can put sealant in your tubed tires (inner tubes in your tires) to stop all the flats you are getting, and they say "no, it's meant for tubeless only", you can tell them they are wrong, leave their shop because they are incompetent, and buy this stuff for your inner tubes and put it in yourself using a syringe kit on Amazon for this purpose.
Stans No Tubes website FAQ has a question which says, "Can I add sealant to my tubes or tubular tires?" And they respond: "Yes, if the tube or tubular has a removable valve core. If there are two opposing flat surfaces just below the top of the valve, you can use our valve tool to unthread the core and sealant can be installed. We recommend injecting 1-2 ounces (30-60ml) of sealant into tubes or tubular tires. Sealant will not damage tubular tires."
So, there you have it! Use it in your stinking tubes to stop thorn flats and make riding and commuting better!
If you do decide to do a tubeless conversion with Gorilla tape or whatever around your rim, this stuff works too! I converted a non-tubeless-compatible rim to tubeless using Gorilla Tape and this stuff, by following a couple tutorials online, including one Instructable.
This sealant is AWESOME! IT WORKED!
I've had the sealant in my (now tubeless) tires for 98 miles now, and about 30 miles ago this happened: I was riding around with my kids. In order to stay next to them while we rode, they rode on the sidewalk while I rode on the grass/dirt between them and the road. As a result, it turns out, I ran over a *lot* of thorns unknowingly. When I got home, I saw little wet spots all over the tire--about **7** or **8** per tire. Each wet spot was a thorn sticking in the tire, and the wet stuff was the sealant that had leaked out and sealed the hole. But..the tire didn't leak. The sealant worked! I pulled out all 16 thorns, and each time I pulled one out the tire hissed loudly, as the air rushed out pretty fast. My tires would have emptied from 50 psi to 10 in probably 1 to 2 minutes. So, after I ripped out 8 of the thorns in the front tire, I lifted up the front of the bike and hand-spun my wheel for several spins. I could already tell the sealant was getting into the holes and slowing the leaks. I then did the back tire too, removing all thorns very quickly. Then, I jumped on the bike and rode quickly around the neighborhood for 10 minutes or so to ensure the sealant was well-distributed. Within only seconds of being on the bike I couldn't hear the leaking anymore. When I got home I refilled each tire back up to 50 psi. The front tire leaked a little over night that night but held enough air I could have rode it the next morning. The back tire leaked just a few psi. I filled up both tires again, and have been riding many times the past couple weeks with no further issues. The sealant works. Much better than the green Slime!
- Reviewed in the United States on January 18, 2018Size: 16-OunceVerified PurchaseI used this to seal the Mavic Yksion Elite All Road tires I purchased here on Amazon for my Diamondback Century 4 Carbon bike. I wanted to go with a tubless setup as I was tired of getting pinch flats from running over sticks and the like on rougher trails.
Using it is easy enough. I used this sealant injector that I got here on Amazon: Tubeless Sealant Injector Syringe and Presta Valve Core Removal Tool by KOM Cycling - Designed for Stans No Tubes sealant and other sealants
Steps to mount tubeless tires (for road bike/gravel/cross tires, mountain bike is similar but amount of sealant will be about double and pressure to inflate to is around half, just look at the sidewall for max PSI when seating the bead):
1. Make sure your rim is tubeless ready, and seal spokes with Rim Tape if needed. I used Stans No Tubes Rim Tape: Stans No Tubes 10yd x 21mm Rim Tape
2. Install Valve Stems. Get the ones with removable cores; it helps with injecting sealant. I used these 35mm stems from Stans No Tubes: Stans No Tubes 35mm Presta Universal Valve Stem (Carded Pair for Mountain)
3. Install Tire on the rim. Try your best to not use tire levers, as it can mess up the bead on the tire. Tubeless tires typically have a VERY tight bead, to keep the tire from "burping" off the rim. They sell lubrication to get them on, but I just used a bit of soapy water on the one tire...the other one I was able to get on no problem. Tip: Install the label on the tire above the valve stem. It looks clean and helps you easily find the valve to inflate tires.
4. Seat the bead. This is the trickiest part. If you have an air compressor, I'd recommend using it here. You want as much air through the valve stem as possible (remove the valve core at this point). I had to get a special inflator gun for me to get enough air through the valve for it to work. I used this one: TYH Supplies Tire Air Pressure Gun Inflator Gauge with Chuck, PSI / BAR Dual Measurement up to 174 PSI, 1/4-inch Flexible Hose, Accessory Kit, Schrader to Presta Valve Adapter, 20 Valve Caps. If you have problems getting the bead to seat, you can put a tube in, inflate the tube, which will seat both beads; then CAREFULLY remove the tire by popping ONE bead off. This will leave only one bead for the air compressor to seat, and works much easier if you're having difficulty seating both beads at once.
5. Once the bead is set, fill the injector with 2-3 oz. of tire sealant, and inject it through the valve stem. I recommend angling the valve stem so that it's not directly at the bottom of the tire, but rather off to the side, at about 4 oclock or so; this prevents the sealant from wanting to come back out of the valve.
6. Reinstall the valve core, and inflate the tire to close to it's max pressure, typically 70-90 PSI will do the trick. You may hear the tire pop a bit as the bead settles into it's final position.
7. (optional) take bike for a short ride just to make sure the tire is seated okay. I took my bike for maybe a 5 minute, 1 mile ride or so just to quickly ensure they were seated.
8. This is one of the most important steps in my opinion. Get a cardboard box and fold the flaps in so you have a nice, level method of lying the tires on their sides. Lay each tire on its side for 24 hours, to allow the sealant to get into the tiny crevices of the bead. After 24 hours, reinflate, and flip them over to the other side, and wait another 24 hours. Then you should be good to go.
After following these steps, my tires have held air incredibly well. I read a lot about how you need to inflate your tires more using a tubeless setup, but my tires have not lost any appreciable amount of pressure in the 3 weeks it's been since I've completed the steps above. If you get a slow leak or it doesn't seem to be sealing well, add another ounce or so of sealant..sometimes it just wants a little more and that's enough to solve the problem.
So far I've been super impressed by how well this has worked, and I love the tubeless setup. So much nicer to not have to worry about pinch flats, and I can run 30ish PSI less than I used to without sacrificing efficiency, and the ride quality has improved tremendously. I highly recommend going tubeless if you are on the fence!

5.0 out of 5 stars Buena calidad
Size: 16-OunceVerified PurchaseHe probado varios líquidos para tubelizar, de varias marcas (en concreto tres, con éste), y siempre usando la misma candidad (yo utilizo unos 90ml para un neumático de 29" y balón de entre 1,9 y 2,1). Mi impresión personal (es algo difícil de medir) es que este líquido sella mejor, y dura más sin deteriorarse (tanto dentro del neumático, como en el bote), que los otros que he probado, por lo que he vuelto a repetir compra.
El precio me parece correcto, no es el más barato (ahora mismo es en torno a un 40% más caro que las otras dos marcas que he probado) pero en mi opinión merece la pena, es un producto que no estás usando todos los días, y de momento para mi es la mejor relación calidad - precio. El ahorro está en que me dura más tiempo, y tengo la sensación de (ya digo que esto es difícil de medir) que usando esta marca uso menos cámaras de repuesto en ruta, por pinchazos que no sellan. Esto último no sólo es una ventaja económica, es sobre todo comodidad y seguridad.
Yo lo recomiendo.
