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.

Seals it up

  • Familiarity: I've put it through the wringer

What more can I say? This stuff seals it up. Works really well in my tubeless mtn bike tires, and also does a surprisingly good job in my CX tubes against goat heads here in SLC. This stuff is magic!

Great product, great value!

  • Familiarity: I've put it through the wringer

I use Stan’s for my road bike and mountain bike, so I bought the quart jug. It’s effective, and the quart goes a long way.

All of the punctures that I’ve had on my treads have sealed, but if you slash your sidewall, nothing is going to save you. I know from experience, dude (said like Chris Farley in Billy Madison).

No More Flats

  • Familiarity: I've used it several times

Used this on my gravel bike and haven't had a flat since. It's super easy to install and not as messy as some other brands. A little bit goes a long way. I put 60ml in each tire and haven't had to put any more in for the two months since I went tubeless. I'm sure I'll have to soon, but this bottle will last a long time!

What More Can I Say?

  • Familiarity: I've put it through the wringer

Not really much more to say here, folks! When I wrote this review, there were 128 other Reviews that have given this a five star review, it's great. I've also used the Stans Race Sealant, but honestly this does the job great. Never had any really issues - anything that the normal Stans couldn't seal wouldn't be able to be sealed by the Race option either.

Do yourself a favor and grab a bottle to have around, never hurts to have some spare sealant. Would recommend also grabbing a Stans Sealant injector (SNT0016) and a Park Tool Valve Core Remover (PAR0273) to make it easier.

Lose the tubes

  • Familiarity: I've put it through the wringer

Stan's sealant hasn't let me down yet. It's good to have a quart of Stans to replenish your sealant every few months. Works great in my mountain and gravel bike!


  • Familiarity: I've put it through the wringer

You can never go wrong with Stan's Sealant, it has been my go to for years.

Back for more

  • Familiarity: I've put it through the wringer

I switched to orange seal for a time because i had a sidewall puncture (a sizeable gash to be clear) that dosing with stans failed to get it to seal and when dosed with orange seal it did finally close up. So I spent the next year going back and forth between both. In the end, both seem to work well in most situations. I have mutliple bikes and switch back and forth regularly (fat, plus, rigid, full squish, hardtail etc.,) so although I abuse them often, there is significant downtime periodcially on a particular bike. What I have found with tire removal, orange seal seems to leave a thick coating on the interior of the tire vs balls/lump that build up with stans (and the stans liquid evaporates away?) . Suffice to say I'd happily use either, but stans edges out of price and perhaps the tire change/cleanup...

This is Good Sealant

  • Familiarity: I've put it through the wringer

This is good sealant. It does the job and the jug means you've got plenty to refresh your tires every few months. It's kind of messy to work with (but what sealant isn't?) and stains concrete and other things when spilled, but it stays fresh in tires for a decent amount of time. I wish it was a bit thicker, but Stan's Race sealant which is much thicker tends to clog up valves and sludge up in the bottle.

Best Option!

  • Familiarity: I've put it through the wringer

The only way to go! I've used Stan's in all of my bikes and have never gotten a flat.


  • Familiarity: I've put it through the wringer

Stan's definitely doesn't stand out. It works for small pinhole punctures, but definitely struggles with larger holes. I love Orange Seal for that reason, but it makes a freakin' mess inside your tire. At least with Stan's there is no mess... you just pay for it with minimal puncture sealing performance.

White Stuff

    I've used Stans tire sealant in my mountain bike, road bike, and cyclcross bike and I've never had an issue. Easy to measure and pour!

    The Good Stuff

    • Familiarity: I've put it through the wringer

    Stan's is just amazing. It has been years since I have had a flat. The last time a had a flat I chose a bad line while ripping through a familiar rock garden and popped my tire. Stan's was everywhere but as expected it couldn't stop the 1/2' gash in the tread. Prior to that my last flat was a pinch flat prior to going tubeless. I once was running too low of tire pressure and folded the tire in a corner pulling the bead off the rim. The gap between the bead and the rim filled with dirt. Stan's sealed it up just fine and I was able to finish the ride with a top off via a hand pump. I could not be happier with the product.


    • Familiarity: I've put it through the wringer

    No more worrying about getting flats! I love the peace of mind when out on a big ride knowing I wont flat everytime things get a little rocky. Lasts forever in your tire so this bottle will go a long way.

    The Original, The Best

    • Familiarity: I've put it through the wringer

    I've been riding w/Stans in my Maxxis tires for about 2 years now. With regular maintenance every 3 months or so, I've never been walking or booting a tire. I've tried another brands with no success so clearly Stans has the winning formula. I hate how messy it is when I get a huge puncture so be sure to clean your bike up as soon as you get home or it's a beast....the only reason I've given it 4 stars. Tire sealant is one of those things you only know when it DOESN'T work so it's easy to hate but I've seen it seal some very large punctures. Stans for life.


    • Familiarity: I've put it through the wringer

    Great sealant for your tubeless setup! Go tubeless and flats are a thing of the past! Easy to use and pretty easy to clean up after those messy tubeless tire setting sessions! It lasts a long time in the tire. I usually only need to replace the sealant maybe once a season. Very reliable. Go with Stans!

    Pesky Flats a Thing of the Past

    • Familiarity: I've put it through the wringer

    Ditch the tubes and go tubeless! I've been running Stans for 3 years now and it is one of the greatest mountain bike inventions in the last decade. Just put about 2 oz of sealant in your tire and it will seal up small holes you might get from rocks, thorns, ect. It really is a must have for any tubeless setup.

    Stan's the Man

    • Familiarity: I've put it through the wringer

    As basically every review here states, stans is THE answer in tubeless sealant.
    It's reliable and a little goes along way.
    I used to be very anti-tubeless, and I finally feel that tire and wheel manufactures have caught up with tubeless technology.
    I've been using Stan's sealant exclusively for a couple of years and honestly cannot remember the last time I got a flat tire.
