Stan's NoTubesOriginal Tubeless Sealant, 500ml(Return to Product Page)

I have tubeless on my road, MTB and gravel bikes. Use Stans sealant on all 3. Easy to use this for new tire set up and to add an ounce or 2 with injector thru the valve which I do about every 3 months. I have had bad luck this season with a number of pin hole punctures on my road and gravel bikes once I put over 500 miles on each set of tires. The Stans sealant squirts out all over the bike and me and hasn't sealed once.

I was able to plug the holes with bacon strips although the holes were really pin pricks. The sealant then holds on the strip. I have always used Stans, but may try some of the others to see if they seal holes better. My road and gravel bikes were new this past year and both came with Vittoria tires. May switch back to Michelin or Continental as they seem to have better wear life and more robust puncture resistance although I have enjoyed how the Vittoria's run with the Stans from a performance standpoint.

Stan's sometimes gets some negative feedback. It's not as good as they proclaim! It doesn't have glitter in it! The Bontrager Sealant does!

Well, even I think of switching to Orange after all the negative hype, but the truth is that Stans works for me. I've had it seal 8...yes 8 punctures in one ride alone.

A couple weeks ago I was out in a semi-remote part of central Oregon. Of course I picked up a goat head when I was less than half way through my Century. And of course before I could resists pulling it out of my tire, I did pull it out. Yikes the sealant was oozing quickly. Argh, I didn't want to deal with installing a tube for this ride!! So, I rubbed some dirt on it and rode off hoping it would seal and I could forget about it.

I made it home hours later, tire full of air. That was 2-3 weeks ago and it's still holding the same air.

If you need flashy, sparkling glitter in your life, they make a sealant for that. They make snow globes with it too. But the truth is, Stans Still Works as it did when it first was introduced!

Stan's is the best for a flat. I don't ride without it. If you are fixing a flat in the garage or on the road in the middle of nowhere, have some Stan's on hand.

I do not recommend drinking this sealant - but it works great in tires. I started with Stans years ago and tried others lately - none of which worked as well or easily as Stans - so I am back!

Been tubeless for a few years and this has been my goto product. Not had a flat since going tubeless (knock on wood)

Easily handles what rocks and gravel throw at it. I've never been stranded in the hinterlands using this sealant.
