Just had my first puncture where sealant wouldn't 100% seal. Riding on 9W yesterday and was pulling up to a stoplight and noticed speckles of sealant on my rear seat stays so I pulled to the side on a busy intersection and rotated my wheel and added more air. I got about a mile further and stopped again to check if the tire was holding and the tire had bubbles of sealant. I pulled out my Dynaplug kit and pushed in a plug and refilled the air and as of this morning the tire has held completely. Now to be fair this kind of puncture would of 100% killed any kind of tube. Besides having to wash off the sealant, going tubeless and using Dynaplugs was super easy

Good job. No doubt the tubeless cynics would be horrified at having to wipe a bit of sealant off the frame! 😂

Yeah, not a big deal if you have disc brakes. However, it is a bit tedious getting the sealant out of the nooks and crannies of a rear rim brake.

Perhaps a soft bristle brush would make quick work of it? Maybe even an old toothbrush?

fwiw: I use Orange Seal, and have disc brakes. It never takes more than a minute to wipe off the sealant after a puncture.

Can you say *******??

edit: apparently not.

It's amazing how the sealant can find its way into tiny spaces on a rim brake. I used to resort to Q-tips or the ultrasonic cleaner to get it all out. I only use tubeless on my bikes with disc brakes now, so it's not a problem anymore.

I am sure if you absolutely can't get a tubeless tire to seal it would be like hell but all the "horror" stories I have heard are a bit dramatic IMO. The splatter you see is due to me running much higher pressures than I should be since at my weight I should be running 60-65 PSI but I was running 80 PSI. Number two, people always complain how sealant got everywhere and how they magically were soaked with sealant, yet if you are running road tubeless there there really shouldn't be more than 2oz in each tire thus how soaked can you get, since my clothing kit was completely clean. Lastly, all of these sealants are water soluble thus cleaning them is super easy unless you let it caked on and let them completely dry out for days on end. I literally sprayed down my bike and got 80% of the sealant off and then wiped down with a microfiber cloth and got the rest off. Frankly this was no dirtier than cleaning after a wet ride.

Dynaplugs are genius.

As for the rim brakes, I don't bother cleaning it off them. You do get a bit of clag on the middle of the caliper but no worse than any other crudenate.

Jrasero: Semi-related question: Does the Varia work OK when covered with sealant as shown in your first photo?

Good to have feedback on the product. Seems to work well.

Coincidentally had my first tubeless puncture on the go last week (mtn not road bike) and the Blackburn kit I've been faithfully carrying for a year didn't seal the small hole, only slowed the leak and I had to pump every couple miles to get home. Now am wondering if it's the condition of the patches, the patch material, my technique, door #4. Can switch brands if warranted.

Back home I scraped the fluid reside off the carcass from the inside and applied a tube patch. Worked, back in business.

Also found my pump with its thread-on chuck would unscrew the valve core on removal. Great. Might swap for a flip-lock pump if this proves chronic.

Learning this system is a process, but it took a year to get a not self-sealing leak, so that's a plus.

p.s. Anybody know why some sealant brands want CO2 flushed from the tire after using a cartridge? Does it got into solution like a carbonated drink?

still worked lol

One claimed advantage of Dynaplug is that the plug is supposed to be a permanent solution that does not need to be removed and the tire does not need to be patched afterward.

This is not a tubeless sealant answer, but CO2 is a smaller molecule than air (i.e., mostly N2 and O2) and thus more prone to leak out of the tire (or tube), so it is recommended to deflate and re-inflate with air after returning home.

I think CO2 (330pm) is bigger than O2 (292pm) or N2 (300pm)

but they’re all a similar size.

Pretty much any plug is a permanent solution. If it holds air on your ride home, it’ll hold air until the tire is shot.

This has been my experience too, especially with mountain bike tyres. When I was running UST tubeless without sealant I plugged loads of punctures with simple bacon strips and never had one fail. Dynaplugs are just easier to use.

I always wonder about tubes + sealant. Which is common with tubulars. Would plugs work with a tube?

Dry sealant is no longer water soluble. Ammonia works to get it off.

I was referring to their respective kinetic diameter.

Molecular Weight (Da) and Kinetic Diameter (Å) of Gases Encountered in... | Download Table (researchgate.net)

But after further reading, it appears CO2 leaks much faster than air simply because of the concentration differential between the interior vs. exterior of the tire or tube.

I very much doubt plugs would work with a tube. Plugging a hole in a 3 mm thick tyre is a lot easier than plugging a hole in a tube. It would be like trying to plug a balloon. Maybe someone has tried it?

It would be like trying to plug a balloon… That is inside a bicycle tire.

I am also a massive fan of DynaPlugs. So easy to use and super effective. Sure they're not exactly cheap compared to some other options, but 100% worth it!

Yeah quite expensive. The Micro Pro Pill kit with like 4 plugs is a staggering $64 however it is very small and comes with various tools like a small blade to cut off the excess plug. Refills are $12-$15+ which again is insane since you are getting only 5 plugs at most, granted the whole system is easy and works insanely well plus I hope I am not running through plugs and two I am hoping these help stop prematurely replacing tires which are also very expensive.

I agree Dynaplug is insanely expensive in terms of hardware, but the concept and execution is faultless. So far I have used 3 plugs in 4 years and the tool will last forever. So cost is pretty negligible after the initial hit. I would imagine there are some Chinese knock-offs for a fraction of the price too.

I agree that I think for the money it will last and that I shouldn't be plugging everytime out, but compare it to your cheap $12 kit from Amazon yeah Dynaplugs are quite the luxury tool. I still love it but if you just are getting into tubeless this wouldn't be high on my list, but it would make a great gift to anyone running tubeless

Yeah, the tools are expensive, and the refills are expensive. But if you're looking to save money, you've chosen the wrong hobby. It might be better to take up something cheaper, like heroin.

I've probably gone through 16-18 of the plugs in the 1.5 years I've had a Dynaplug Racer Pro, which helps reduce the cost per use of the tool. When I have the luxury of fixing a slow leaking puncture at home, I use a regular (cheaper) bacon strip -- and I marvel at how much faster and simpler it is with the Dynaplug. For racing, it's indispensable for me.

I also recently bought a Dynaplug Racer Pro on sale which is still pretty damn expensive, but all the online reviews say that it is much easier to use in the field than bacon strips, and you guys have confirmed it.
