It works for cars, so why not bikes? Just like that fix-a-flat stuff you wonder about using, this milky goo seals small leaks and punctures, up to 1/4in. And the stuff works really well. The kit can convert most tubed tires to tubeless. And if you're already riding tubeless, it makes running low pressure and riding through thornbushes, glass gardens, and herds of goathead thorns all the safer.

For those who are wondering, no the sealant doesn't freeze, doesn't alter the balance of the wheel, and can work in any kind of tubeless tire when combined with a UST or tubeless-ready rim. If you have a standard clincher wheelset, bear in mind that you'll still need to prep your wheels with a tubeless conversion kit before taking advantage of this sealant. The one-quart container can seal up to 16 tires.

Only way to go.

    If you ride mountain bikes then you already know all about Stan's. It is the staple when it comes to converting your ride to tubeless. It's relatively cheap and works like a dream. Get on that train and go tubeless, you won't be disappointed.

    Still works

    • Familiarity: I've used it several times

    I started using Stans on my mountain bike 12 years ago. I just went tubeless on my road bike. I expected some fancy new product for road tires. Good old Stans was the recommended product and it worked perfectly. I just had a flat on my wheel barrow. Poured in some Stans and pumped it up, no problem. I guess if it works don't fix it.

    What everyone else said!

    • Familiarity: I've put it through the wringer

    I'm about the stans, works great! I've had it in my tires for 4 years and have sealed even non-tubless tires (though you have to re-up more often). Just got the injector too, GAME CHANGER!

    You could make your own, but why? This stuff works great and your time is better spent making homebrew Skr@tch (Tums, fruit powder, honey, and salt to taste ;)


      This product is one of those that has such a loyal customer following that if you're reading this, it's only likely to pat yourself on the back and join in the love for Stan's no tube tire sealant.

      Used for years, now using on a new fatbike tubeless setup, it works great!

      Sixteen years on this stuff!!!!!!!!

      • Familiarity: I've put it through the wringer

      I have been riding and racing mountain bikes in western Virginia since 1993. Flats were always a problem on the sharp rocks we ride on our side of the state until my buddy turned me onto Stan's tubeless system before my first mountain bike vacation to Northern California and the land of thorns. We had no flats that entire trip. There are many other formulas out there nowadays, but Stan has earned my business. Looking forward to trying his new Raceday formula this spring. Don't be surprised when you call the service number with a question when Stan himself answers the phone. I'm stoked that carries his products.

      Sixteen years on this stuff!!!!!!!!

      The One True Sealant

      • Familiarity: I've put it through the wringer

      All hail lord Stan, King of the Tires and Lord of the Tubes. His realm stretches from the inner rim to the spoke lands, and his dominion over these lands is complete.

      Works great!

        There is a reason this stuff is what everybody uses. It works great! Really can't go wrong with this product

        Highly Recommended

        • Familiarity: I've used it once or twice and have initial impressions

        After buying a ton of tires all summer due to goat heads, the local bike shop suggested a big bottle of magical sludge. We figured we'd give it a try. So far so good!

        Seals your Tire

        • Familiarity: I've put it through the wringer

        Easy to apply in your tire, and works great!
        Been using it on my bike for several years and the only time I've ever had a flat on trail is when i got a small hole, and did not realize I had actually run out of Stans in my tire. Really recommend using on any tubeless setup.

        No tubes, no problems.

        • Familiarity: I've put it through the wringer

        Sealing my tires when I rip off lugs is a lot to ask from some liquid I pour into my tires, but NoTubes seem to crush it. Getting the most out of my tires, and preventing flats left and right, I'm always happy with Stans.

        Adequate for the job, but wanting more

          I've always used Stan's for the tubless set up, but recently I've been wondering whether there's something better out there. The handful of times I've had a puncture, Stan's just hasn't sealed like it claims it should. Perhaps it's running a lower tier pressure (24PSI) but rarely does a puncture seal without the need to utilize a CO2 to over-inflate and seal the hole by directing the sealant. That's a far cry from promotional videos showing a bike riding dozens of times over nails and self-sealing.

          I know Stan's has their Race sealant, which would seemingly be better for punctures, but the last time I had that product in my tires it seemed to dry up in about 1/2 the time of the regular sealant (just under one month in normal summer temps of 75 - 85F) - far too soon to know if it worked in a pinch.

          I'll keep using the remainder of my bottle, but looking for a replacement faster sealing capability and a longer inner tire life.


          • Familiarity: I've put it through the wringer

          I have been using Stan's for a long time and it has always amazed me at how well it works. Great for tubeless setups and for adding to tubes to prevent flats.

          The original

          • Familiarity: I've put it through the wringer

          Have been using Stan's ever since I switched to a tubeless setup. It's always worked well for me. My only complaint is that it sometimes gunks up your valve stems which can make it difficult to add or remove air. But I think that's likely a problem with any sealant.

          Good stuff

          • Familiarity: I've put it through the wringer

          I think Stan's is the best out there for sure. Sometimes though I get very small punctures and I lose a lot of fluid before it 'clots' up. I find myself adding a couple OZs after 100 miles of riding

          The original, the best

          • Familiarity: I've put it through the wringer

          What i use exclusively for sealant. I've heard good things about orange seal but havent had any issues with this so i've never bothered with anything else. Seals up small cuts and punctures with ease.

          easy to clean up

          • Familiarity: I've put it through the wringer

          Easy to clean up and does a great job sealing goat head holes.

          Doesn't last forever and needs to be refreshed depending how much riding you are doing. I like using the Stan's no tube injector so I don't have to bust the beed.

          Magic liquid

            It sealed up a decent size hole in my tire and is still holding up after a few rides. Easy to install and performs well. Definitely would recommend this if you are setting up tubeless.
