Is this the HOLY grail of Tire sealant

[@seitenryu6844]

The limitation for me has always seemed to be maximum pressure that it will seal. Most narrow(25/28mm) tires simply lack the structure to properly seal medium size holes when used at higher pressures. We're always given the line that "tubeless systems allow for lower pressures", but the part missed is that tire pressure is simply a mechanism to support the mass of the bike+rider system. There's a lower limit that can be tolerated for handling and performance reasons. The other aspect that can be daunting for recreational or casual riders, is the maintenance required to retain the sealing action. It's a lot of marketing to sell a product that may work in many cases, but isn't the cure-all that it's often perceived as. Hopefully we'll see things unify and the issues fade away.

tbh the thing that most excited me was the carbon fiber recycling. we really need to figure out some way to not fill up our land fills with our used carbon fiber stuff

[@joelzylstra2971]

I saw that, Chris King is making rims with it. There’s gotta be a catch though. It would be crazy popular otherwise. Cost perhaps?

[@fleurdelispens]

@@joelzylstra2971 or it's just super new. Takes time for things to catch on

[@tomgeorge3759]

On the other hand, by using it in tyre sealant it just eventually ends up in the oceans no? Whether down the sink or down the gutter it goes into the water cycle. If it gets filtered, my guess is it just ends up in landfill again. Nevertheless that’s no better or worse than all the particles in other sealants.

[@mikepease9858]

The nerd alert podcast has an episode on this subject. It is well worth a listen.

[@sAmiZZle82]

Wayno, the Silca Replenisher is available for topping up. It's just plain sealant without the carbon fibres that can be injected in the valve for convenience

[@andarenbici]

They have a second lighter "top off" sealant that supposedly would work for the applications you mention as limitations here. So they have thought of that to some extent.

[@TonyTurboRST]

Speaking sense there, I like it

[@darrenhaines1]

Occasional riding friend of mine with a giant (factory tubeless) just takes it to the bike shop to replace the sealant every 6 months or so when he goes to ride it and can’t pump up the tyres. So I see the currently model being a win win for bike shops

[@waynosfotos]

Yep, sealant needs to be maintained.

[@Wildschwein_Jaeger]

[@mickchaganis6607]

Just putting my tubeless tyres on some used carbon wheels I picked up, decided to chop up some carbon strands into about 5mm lengths and put about a heaped teaspoon into my tyres then put 40ml of latex sealant in, seemed to mix ok, popped the tyre on and well......who know until/if I get a puncture 🤪

[@savagepro9060]

One day, in the future: Waynos Smart Sealant. This crawls all over the tube or tyre. Finds the puncture, then seals it.

[@hallisoft1926]

The best sealant I've used is Stans Race Sealant. This also must be poured into the tyre because it will seal the valve hole. The issue with this sealant is that the tyre has to be removed to top up the sealant. Silca have removed this issue by providing a top up fluid. The other issue with Stans Race Sealant is that it comes in large bottles and half is wasted because it dries out before it can be used. Silca take note.

[@janeztomazic5546]

agree, I was using the Orange seal that was hyped on forums but its total crap compared to Stans

[@akboiboi]

@RollinRat May I know what you recommend in this case? Im intending to use them in road tubeless tires, thanks!

[@akboiboi]

@RollinRat thanks for such a detailed response, really helped to put things into perspective and manage my expectations! I suffered 7 punctures on my new gp5000 clinchers during my race (mechanics can't determine where was the system repeatedly compromised, rim tape was ok, nothing stucked in tyre etc) and in fact it's running fine 3 months since the race. This experience forced me to take a look at tubeless setups for road, which brought me here 😂😂 Noted on the orange seal regular recommendation, any thoughts about Silca's wonder sealant? seems to attract extremely polarising reviews! 🥶

[@akboiboi]

@RollinRat 🤣🤣 appreciate the brutal upfront truth, i have my clinchers on standby with latex tubes (maybe i'll experiment putting sealant in them). I have 3 months to play around with tubeless before race day. Let's see where this takes me! For now i'll probably heed ur suggestion and go for orange seal (: cheers, have a great weekend!

[@ZenEndurance]

Just take some pet hair or beard trimmings and chop it up into 1-2 cm bits and throw it in the tire with your sealant. It travels with the sealant and helps clog holes. Biodegradable, cheap... it clogs your plumbing pipes, it'll clog tire holes.

[@Hambini]

my solution to tire sealant - use a tube.

[@waynosfotos]

Yep, still works

[@41istair]

I recently replaced my Stans-filled rear MTB tyre due to tread-wear and the old tyre had 17 massive 1-2" thorns sticking into it, from the last couple of years. Sealant lets you ride, saving hours of tube-replacing maintenance! I am currently trying Vittoria sealant and have moved away from FinishLine on my gravel bike, as that gels over time and does not flow to a hole. Latex sealant forms the equivalent of a latex innertube, as it dries over time. Wheel rimtape needs to be replaced every 2-3 years, as air loss will eventually occur through the spokes & nipples. If I had to use tubes again, I would go for slime-filled, based on good experience on holiday bikes over Greek thorn bushes.

[@waynosfotos]

@@41istair if you buy tube with removable valves you can put your favourite sealant in. Easy

[@WonderFlea]

You mentioned running tubulars with sealant, may I ask what you tend to use? I've been using Stans no tubes and have had varying results with different tubulars. That being said, I've put the sealant into the tubular from the beginning, not a patch method like you describe. Personally I'd like to use the patch method because I've noticed that after adding the sealant it doesn't seem to spin as long (I'm suspecting an internal rolling resistance). However, I have also seen a benefit of having the sealant in the tubular from the beginning. I had a puncture while riding, had sealant spray a small stream all over the place and it patched it while ridding, no need to stop.

[@mickchaganis6607]

I wonder how hard it would be to put in a tube at point of manufacturing like ' Slime tubes ' . Like you say a 2 part system, dry carbon blown in then the liquid? I'd pay a premium for that over a standard tube.

[@jamesmckenzie3532]

Tubeless tyres on autos relies on the power of the bead and the thickness of the tyre itself. Mavic, as you stated, tried this. Their tyres were way heavy. Would never be used in racing. For the daily commuter, this wouldn't and shouldn't be a concern. For the racer, they could use tubular or tubed tires...

[@andyeunson270]

Exactly. I used the Hutchinson UST road tires quite a bit with Shimano rims. It worked really well. Those tires had a carbon fibre bead which would not stretch. Those tires weighed more than a regular tire by itself but not that much more than a regular tire and tube.

[@Wireman273]

I use Vittoria tire sealant. I got a 6-7mm hole in my tire and the sealant did the job. I did have to clean sealant off the rim and frame but that was done after my ride. Vittoria can be injected through the valve stem. The Pirelli tires I use make adding sealant before they seat to the rim a deal breaker for me.

[@heywoodjablowme8120]

Good info. Thanks 👍

[@ChrisFacciol_LIFELINEPHOTO]

Bullshit !! Then what did you do? Oh yeah .. you had to take tire off and patch the tire from inside unless you plan to keep riding and praying the carbon threads keep the hole filled … it DOESN’T !! Add into the mix your 4 SCHEDULED FLATS FOR MAINTENANCE and you’re just entering the RETARD CYCLIST zone !!!

[@stephenjohnson4742]

This 2 part system would be a suspension. I think silcas chemist is formulating that process and probably in the future because the tubular and tube tires are still in use.

[@falcoperegrinus82]

Seating a tubeless tire can be done with a conventional pump but it's not reommended. Get a pump with a chargeable chamber, an airshot canister, or a compressor.

[@wasupwitdat1mofiki94]

I can't believe the Silca KZbin Ad. They say they have scientists and chemist on staff, yeah right. Those professionals don't come cheap so how are you paying them. Silca is a well known brand but I doubt they have the budget for that kind of expertise. I believe if scientists and chemist did get involved to produce a product that would actually work I don't think we would be watching this video right now and possibly tubes would be a thing of the past. Honestly, when I have a flat, installing a new tube is not a big deal, not at all. Why do they have to keep pushing tubeless on us?

[@waynosfotos]

You could be right about employees. Normally companies that are small outsources this or buy a known product and re-badge it. I can’t confirm or dispute this comment though.

[@eliprotiva222]

[@markozivanovic8052]

What's your recommendation for putting sealant , beefore or after puncher ?

[@waynosfotos]

I use to put before, but i found the sealant just goes hard and eventually attackes the latex tube. So now i put in after i get a puncture, whilst on the sode of the road.

[@markozivanovic8052]

@@waynosfotos thank you. What do you think about new Vittoria sealant? Do you have a some information about that sealant on road tubular?

Perhaps someone can answer with certainty. I heard (never proven or disproven) that sealant does not work in tubes. I’ve put it in but unfortunately didn’t flat to find out.

[@savagepro9060]

It does not work very well in tubes… but it does seem to work about 30% of the time.

It does work in tubes, i have done it many times. The manufacturers say it works better in a tubeless set up, but i have seen no study to confirm this.

[@jamesmckenzie3532]

Ever heard of Slime? It's basically the same stuff without the glitter. All of the major brands can be used in rubber tubes. It cannot and shouldn't be used in latex.

[@D_H_88_99]

I guess for it to work in a punctured tube it would actually have to seal 2 holes. That means the larger sealant chunks need to be able to get thru the tube first without sealing it. 🤷

[@takuan650]

All these messy, expensive and half arsed contortions. Are there any meaningful advantages to be had? I just install a new tube.

[@jamesmckenzie3532]

When you figure out a way to recycle tubes...just to make this relevant, I have six holes in my front tyre. That would be six tubes. Not to mention the environmental costs and the hit you my wallet at USD 10 each.

[@joelzylstra2971]

Way less punctures, like waaaay less. Despite what the naysayers claim, it really works astonishingly well!

[@veloveritas9963]

Tubeless is faster and has FAR less punctures. It’s cheaper in the long run than buying tubes, even though the tires are a bit more expensive to begin with.

[@87togabito]

The advantage is when your mate rides off, not even knowing that his wheel has a puncture that was sealed while you sit at the side of the road looking pathetic as you replace your tube.

[@manoz6194]

@@veloveritas9963 This is the reason why I am switching my rear tyre to tubeless. I am a food delivery courier and there is so much broken glass in my city. I use marathon plus tyres with a heavy inner tube and inner tube sealant but despite that I get punctures and lose business. Today I had a puncture, pumped it back up, it sealed but then after a few hundred metres it burst again and didn't hold air. I hate having to walk home in the middle of a shift

[@MrChippiechappie]

I would call running tubular tyres a major negative, get some tubeless clinchers and put this stuff in and forget about punctures.

[@cosinus_square]

Bullshit, can't sell enough sealant to offset the costs of separating carbon fibres from resin. Chopping it up as is, without separating it, very doable. I've been mtb'ing with tubeless tyres for years, common knowledge if you have a hard to seal puncture, you can literally use dirt mixed with sealant to plug it. Works every time. I assume Poertner realised that, but knows he can only sell race stuff to mamils, we know mamils love carbon. Ground carbon weighs less than sand, volumetrically.

[@waynosfotos]

In the MTB world sealant works fine due to the low pressures. On road it is not as reliable due to the higher pressures.

[@cosinus_square]

@@waynosfotos low pressure for tubeless is not an option, it's a requirement. This is how the system was designed to work. You can't set it up incorrectly and then complain it doesn't work.

I bought in on this tubeless sealant. I now can’t fill my tires up . The sealant blocks the valve stems. After emailing silca without a reply I called. This call was worthless. I was hoping they could explain what I might be doing wrong. Instead I got sorry. So I replace all valve stems only to clog to the point my pump was blocked also. Do not buy this product!,its not the answer
