Please please please stop making great products. My wife is going to kill me when I turn up with yet another Silva product that I need!
You're welcome!
been using this for 6 weeks and so far so good over all terrain, roadside with glass, and rough Australian fire roads inside Pathfinder Pro's. I've only seen a little sealant near the bead where I think I burped a tyre hitting some rocks at low pressure and high speed. very happy so far. Thanks Josh and Silca product team!
Amazing ! Longevity is a key aspect here ❤️ Thank you for bringing this in 🚴♂️
Hi Josh, fantastic product and great video. Love all your products and glad to see the company thriving. Have a good one
This sealant is the only reason I am going to try tubeless road again! Took a 2 year hiatus and went back to latex tubes. Had too many instances of sealant not working and making a bigger headache. Thank you!
Great product, love your channel! Gonna try out the sealant in my Conti gravel tyres soon.
I know you tested it a lot with your athletes but this could also fundamentally change the game for commuters in glass-filled urban environments.... Can't wait to try it
Looks good should last a while here in the UK 🇬🇧. I like the idea of topping up.
Josh, loving the new sealant concept. Funnily enough, I have recently switched to using Stans race (pour in only) and then topping up with regular Stans so looks like I had a similar idea but I have no idea of the longevity of that approach. As soon as I run out of Stans I suspect I will be placing an order. Oh, and please talk to Adam at ZFC to make sure he has stock (your shipping costs to Australia for a single usually tip the balance between a purchase or not!)
Looking to try tubeless for the first time and been searching for a sealant to try as well. Found it!
This stuff is amazing!!! Ive used Stans sealant which was junk and left me stranded. This Silca stuff seals and holds high pressure every time. Thanks Silca.
STANS is the market benchmark buddy.
They invented the thing and possibly has been the best since. Ive tested almost all, run through atleast 60 tires in the past 3 years. Although im looking forward to test this or new ones ive heard rumours about
cant dismiss stans like that.
I didnt have a good experience with Stan’s. I didn’t think it sealed well at all. The Silca stuff is good but it’s got its own problems with clogging valves. Orange Seal works well and doesn’t plug the valves.
@@MasteringGrappling well test that next possibly. Silca has a bit of a neegative for sure when i heard of the foam. Sounds like ir will get on the rotor
I just purchased some Super Secret for the next chain on my road bike and planning on getting some Synergetic for my mountain bike.
Got to test the Silca Sealant last weekend at the Wilderness 101k mountain bike race. I underestimated the rockiness of the trails in Central Pennsylvania and the Bontrager XR1 rear tire was a bit over matched by the rocks. I end up with a slow leak and stopped to put in a CO2. The leak was right at the rim, where its hard for sealant to get to. I turned the bike on it's side so sealant could find the leak and it sealed right up. I finished the race on the 1 CO2 and the tire is currently holding air without issue.
Great to hear Paul and be sure to check that sealant as CO2 is a hardening agent for all natural latex based sealant products, ours included. Changing out that air and adding some replenisher should do the trick!
i ran that sealant with the orange name for a year with no issues. Maybe I never punctured, but I have my doubts about that. I would definitely use a sealant that promised better performance. After riding two seasons on tubeless road tires, I refuse to go back to tubes.
Just used this in my new TCR SLR 1 Wheels.. We'll see how it goes, but if it's even close to as good as it looked in a recent sealant test video I've watched, at the price it'll be the best deal in tire sealants..
Hi, pardon if these questions have already been asked and answered:
In general and or how it refers to the Silca Sealant, just how clean must a tubeless tire’s interior be prior to adding for best performance?
Is there a “shelflife” (in the bottle) of the sealant or refresher that maintains their optimal product performance?
Fantastic work, Josh and everyone at Silca! I still have some left from my previous favorite manufacturer and then trying this!
This looks like an awesome sealant! As someone who has always injected the tire sealant instead of pouring it in, I do have a couple concerns. Two issues that can potentially make it challenging to use the pouring method: 1) Mounting the tire on the rim. I am getting better at it but sometimes I still have difficulty mounting a tubeless tire on the rim. I can already imagine myself spilling the sealant all over while trying to get the last bit of the bead over the rim. 2) Once the tire is mounted, there is another potential issue of getting the beads seated. Occasionally, I need to spray soapy water on the beads to get them to seat. When soapy water does not do the trick, I have heard of folks putting an inner tube and leaving it inflated for a day before making another attempt to get the beads to seat the following day.
I agree 100%, if this sealant is non-injectable unfortunately I won’t use it for all of the above reasons.
@@Wireman273 After trying the "proper" pour-in method, it's actually not too bad. The first time I attempted it, I only mounted one side of the tire and poured in from the unmounted side. That resulted in spilling a lot of the sealant. The second time, I used the Silca-recommended method of pouring in the sealant from a partially mounted - the other side is already mounted - side and I only spilled a little bit. I discovered one advantage of the pour-in method: the tire is significantly easier to seat. I still needed to use an air compressor but I could get the tire seated without using any soapy water and it only took seconds, instead of minutes - sometimes tens of minutes - to get the tire mounted because the sealant acts as a barrier in preventing air from gushing out while you're trying to seat the tire. With the pour-in method, I do recommend making sure that you can get the tire mounted first before unmounting it partially to pour in the sealant.
Try a rim jack it makes mounting easier
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
@@michaelbattin6717 Was the Silca sealant with fiberfoam - not the replenisher - installed using the pour-in method? Or was it injected via the valve stem?
Are there any videos to show this product actually being applied? I've ordered some to use on my sons bike but I'd like to see an instructional video on the product being applied to a tire. Thank you
... clicks cfr link. this content is stellar. somehow, this is gripping. thanks josh.
Thanks Paul! - Josh
Can you clarify -is the sealant in the 16 Oz container the same stuff that comes in the 4 Oz sealant replenisher? If I had tires with a different sealant and I wanted to convert to yours -do I have to re-install the tire again? Once the sealant replenisher is done, what is the recommended procedure?
It's a different thing when your riding, weight on wheels, with the hole being expanded and contracted while riding.
That said sell it in the UK an I'll definitely try it.
What is the shelf life of both products? I seek to try this out on my road bike 28mm tires, and the initial dose is 2oz and graduating replenishing quantities up to 2oz on the 3rd and final replenisher (i assume it's time to replace the initial dose and start over after that). However, the smallest container of the initial dose is 8oz which can last me 2 years in a perfect world. Is the shelf life at least 2 years?
Thank you Josh, Will my Stans dart plugs still interact with your sealant since it is latex based and seal up stubborn punctures.
Yes, these seem to work just fine with our sealant.
Usual up front and science based video sir - thanks. Had already bought some of this,m before watching the video and just installed a new tyre(GP5000 TL) on to a Roval rim (about as hard a combo as exists) and with a little care managed to get 60mm in and only maybe 1mm spilled. Not bad for a road install.
@silca_velo Questions: how do I stop the valve clogging now (with this stuff being better at ‘filling holes’) - is it just a case of replacing the valve inner more often?
What model of iPhone holder and mount are you using in that video l?
Only have 3 months max left of the year now, so curious … if I store the wheel (temp on avg 19C) for the winter and it doesn’t move can I use replenisher next Spring - or just start again? And will the bottle (now open) if sealant stay good until next year?
Thanks.
How does this not clog the tire valve if/when I need to bleed off air?
If this is sealing with the fibers, will it still work well if a dynaplug or dart it used?
Very cool! I just topped up with OrangeSeal. Doh! Do I need to remove the tire and completely clean out the OrangeSeal, or can I leave the tires seated, suck out the bulk of it and add your stuff?
We have not tested whether mixing is option. We recommend pumping out the bulk, clean what you can and then proceed with the pour-in method.
I was initally super excited to give this sealant a try after viewing this video. However, when I got a puncture on my most recent bikepacking trip I was totally let down by its performance. Backstory: I got two tiny holes (one in my side wall and one on the top of the tire near the knobs) simultaneously when my wheel hit a rock on a fast descend and the tire bit the rim. Perfect opportunity for the fiber foam to do its job and take care of these holes, I thought. After about an hour of messing with the tire, spinning it and even adding more Silca specific replenisher I had no luck. It seemed the fiber foam was not building the so-called scaffolding that was advertised. When I later popped the tire off to put in a tube I was surprised at what I saw. Almost 100% of the fibers had clumped together in various parts of my tire and formed little stalagmites. There was virtually no more fibers dissolved in the sealant liquid that would be available to do its job. Super dissapointing. I should also add that I topped up my wheel with 60mls of freshly shaken Silca sealant right before departing for the trip. I'll definitely be sticking to Stans in the future.
Sorry for your experience, unfortunately the formation of stalagmites means that you waited to long to replenish. This happens with all sealants especially Stan's as has been well documented for more than a decade, so be sure to give your tire a shake once a week and listen for the sealant to thicken, once it thickens, no matter what the brand, you should be replenishing.
Hi Josh I love your innovations, I've been on again off again with tubeless and was going back tubeless with a set of Vittoria Air liners when they arrive next week or so and then your email arrived in my inbox. Do you know if using Silca sealant with the Vittoria Air Liner will work or do you think it is an either or option or perhaps even a better option without the AL.
I love Vittoria Air Liners, but they can make tire installation harder than you ever imagined. We've been using/testing them in our shop for almost two years and I'm pretty much the only person (Josh) who can consistently get tires on/off without resorting to extreme measures, and even then, I've blood blistered my thumbs more than once. If you're using the liners, I would not recommend putting SILCA sealant in during that process as you might end up stuck to your floor in a puddle of sealant and tears (been there.. done that!). I would probably just go with replenisher if using air-liners as you'll want to just pump it through the valve and be done.
Great video. Why is it harder to seal at higher pressures than lower. I’d think it would be harder with lower pressure- less air pressure trying to escape would make it harder to seal but clearly not. Would love to understand. Thanks!
High pressures are just so much more effective at pushing the sealant out of the tire.. you need the sealant to have a few seconds to begin to harden when exposed to air and under high pressures the sealant is flowing out too quickly to harden, sort of like cutting an artery vs cutting a vein, the skin and blood are same, but the pressures are very different!
You got me interested 🙂
Can you bleed air from the tire to drop the pressure after sealant has been poured in, or will the sealant clog the valve?
Will this sealant make it In and out of a tubeless injector like the park tool injector? Looks like amazing sealant!!!!! I want some.
Funny you should ask...Here is the new video that talks about the use of an injector....ruclips.net/video/oPJF63IBnsM/видео.html
when will this be available across the pond in europe
Looks outstanding Josh. Any concerns using the sealant in wheels with foam inserts?
Came here to say the same thing about foam inserts.
@@alantaylorfarnes Josh replied on CyclingTips and said inserts are fine with the new Silca sealant.
I just finished waxing my chain with the secret hot melt. Can you do a video on how to go from tubes to the silca sealant ?
Thanks
In the works! Thanks
If your looking for a demo set of wheels I have a set of 404s. lol
Hi I have a question. I ride Enve 3.4 SES road wheels with Vittoria Open Corsa tires. I’ve used Orange and Finish Line sealant in past years. My size requires a tire pressure of around 100-110 lbs. In this video you were talking about 30 lbs. Will your sealant work at higher pressures?
The carbon allows for better sealing at higher pressure than any other brand, but the higher the pressure the smaller the hole it can seal. We consistently seal holes of 5mm at 90psi. I'd also check out the SILCA tire pressure calculator, I don't know your weight or tire size, but with modern wide bead seat clinchers and tubeless tires that tend to measure oversize, 100+ psi pressures are not so common anymore. Check out: silca.cc/pages/sppc-form
Thanks, I used a tire pressure calculator before posting and it said that was the pressure to use. My weight floats between 230-240 lbs. My Vittoria tires are 25 mm. My bike frame can only accommodate up 28 mm. My Enve wheels were designed for 25 as a perfect fit, but will take 28 mm, in theory. The side walls are straight and flush with 25 mm, the 28’s would probably bow out past the rims and I don’t have a lot of clearance in the rear. Thanks for your help.
Hello SILCA team,
my Gravel wheels are well setup and I have just recently setup my ZIPP 858 NSW with Specialized S-WORKS TURBO T2/T5 2BLISS READY, it installed really well.
However, during a long ride, I had a snake bite puncture riding over a big whole.
The 2 wholes were roughly 2 - 3mm in length. One sealed but the other keep on leaking sealant and deflating the tyre.
I added sealant and even plugged the whole but for some reason, the whole would still leak, mostly when weight on it on when I’d look at it with my finder.
I’m a bit confused because I think that I followed all the right steps. Any idea what I might have done wrong?
BTW, I inflated the tyre with around 72PSI (max for hookless rims)
Right now, I’m prepared to go back to inner tube TBH.
Hi Josh: Great content. Hey, I'm a newbie, in that I don't have a tubeless setup just yet, but I'm wondering how much of your sealant would I need for my setup if I'm running a 700c 25mm road tire? I don't know how to figure out how much of your tire sealant I would need. Is there any instructions on the bottle itself that tell me how much to use? Thanks in advance!
There is a QR code on the side of the bottle that takes you to installation instructions including a chart of how much to use in different size tires. You are probably looking at 2oz/60ml each for your tires!
@@SILCAVelo Thanks. I will look for that bar code when I receive the sealant.
Do you still have any use for if you have them "stans darts", does this product work with them? And have an other question, will this work using on Fatbike-tires during wintertime or will it freeze up? Can you mix antifreeze to be able to run it as far as down -25C°(-13°F)?
Hi, with Orange or Stans, you can check your level through the valve with a small zipp tie. How do you suggest checking when you need a refresh. Does it pool when left stationary or is it always in a foamed state?
Great question. Hope to see an answer here.
It lasts so long you don't really need to check the level. And if you had to pop a bead off once a year to check/top up, that doesn't seem too much to ask.
@@joshuaperry6091 lol what are you talking about? He asked about checking the level....the stuff lasts at least 12-14 months. Tell me how I'm wrong.
Most riders will probably be putting new tires on before they need to check sealant levels.
It only foams when agitated and even then, it's minimal, so you can definitely check it with the zip tie method. Life expectancy is 12-14 months when replenished quarterly, so i'd say check it and replenish every 90 days and then replace every year or so, or when you replace the tire.
Using the replenisher on latex tubes; would that result in not having to inflate the tubes everyday. If so then what would be the general time necessary to reinflate those latex tubes?
Replenisher may slow the pressure loss in latex tubes but will not eliminate it, the pressure drop is more related to the solubility of gasses into latex than porosity as is often suggested, so CO2 for example actually will migrate through the latex tube and sealant by temporarily going into solution with the rubber and than transitioning out the other side..
I have a question: Why no Ammonia? It seems like an important ingredient and the small amounts in sealant are comparable to the amount naturally discharged by the human body
I got my very first puncture on the weekend and the STANS has failed me. I don't know why wont seal the pin hole puncture but I won't be using the rest of the bottle I have.
Josh, I think you actually have a couple of scenarios: The first, covers the scenario you raise. That is, you get a puncture and just roll through it and may not even know it ever happened. The second is an obvious puncture, where you dismount and rotate the hole to the bottom, where the sealant is pooled. The particles are probably designed around scenario No. 2.
This is where the foaming action comes in, the foam allows the sealant and particles to be more mobile while riding.
I didn't get their solution to "seal the valve" problem? Do we inject the second liquid? I'm having this problem even in other brands, I can imagine how difficult the situation should be with additional fibers in it.
The liquid sealant can get into the valve, but the fibers will actually dam up the valve hole and prevent sealant and fibers from entering the valve from the tire side. When you pump, the air from the other side simply blows away the fibers and sealant, so in practice there is really no difference between us and the other brands in terms of valve maintenance.
Couple of questions:
How Green is this product?
If you take your bike on a Flight, does the sealant freeze?
The information provided on the product sounds great
Well, considering the carbon that is used in the sealant would be serving no other use but to sit at a landfill forever, I'd say it's a fantastic way to recycle.
@@HolmsOnBikes I think we are both agreed on that aspect, however that doesn’t really answer the question as many other products will be sued/produced to create the Sealant.
We are working on a video about this, but we have 3 pillars of 'green' in this product, 1. the latex is from Vietnam and is organic, the same supplier provides latex for high end mattresses and a price premium is paid to ensure the farm remains organic. 2. we use propylene glycol which is FAA certified as environmentally safe as an aircraft de-icer, most brands use ethylene glycol which is same as car anti-freeze and is a ground water contaminate and deadly to animals. 3. the recycled carbon that would otherwise be landfill.
Clearly anything that is made has some cost, but we feel our approach has a much better environmental footprint than any other.
@@SILCAVelo Thank you for taking the time to reply & give a breakdown of what you make & ultimately stand for. I am aware that products companies make are generally always good, however it makes much more sense when purchasing a product to be as Green as possible.
Thanks :-)
Can I use my 8oz bottle to refill my 4oz bottle of replenished to get it into my tire (Presta valves)?
Do I need to remove and clean my tires of the previous sealant before using your product?
Yes, different sealant brands are generally not compatible with each other.
Question - will in possible to run with inerts like the Tannus Armour tubless? Or does it stick the slots inside?
We've done lots of testing with the Vittoria style inserts and it works great. Inserts with very high surface area may end up capturing a lot of the carbon fiber and holding onto it.. but have not tested directly sorry!
@@SILCAVelo I will give a feedback of my testing.
How do you know your sealant is still 'alive'?
How does it behave when filling the tire with CO2?
Would you say that it works better at higher pressures than other sealants on the market 60-80psi range?
What's the recommended amount to use for road, gravel, mtb tires?
I normally seat tires before I add sealant to them (through the valve) to avoid a mess and wasting sealant. I'd totally sacrifice the sealable hole size for being able inject through the valve. Maybe that could be a road specific sealant?
We are far and away better at high pressures.. in the beginning my vision was to make a high pressure specific sealant, but as we began testing we realized that it was just better everywhere and all the time, so it just became one product. With a little care, I can pretty much always get it set up without mess, but there definitely is more risk of mess than injecting through the valve, so just depends on how you prioritize a potential mess vs improved sealing power
I'm not on Silca yet (till my supply runs out), but in my homemade brew experiments, I've had to redo 25-27mm road bike tires over and over and there is no mess installing once you get the hang of it (removing I still lose a bit). The trick is to never be working the tire anywhere near the (gravity assisted) puddle lol.
How much sealant is needed for two brand new tires?
One of the worst aspects of tubeless sealant is when my many bikes sit for weeks or months and the sealant solidifies inside the tire (I use Orange) or the dreaded booger. You can’t get that crap off your tire without some serious work. I want to be able to clean out the tire at some point, also clean the rim to reinstall tape, which is the absolute key to good tubeless performance. So a gunked up inside is not optimal. What happens to the Silca sealant when it ages? Can it be cleaned out? Hard? Easy? Thanks.
Good luck with any brand. If your bike is going to sit for long time take the sealant out the tyers. Also this stuff is like glue the tyer will basically stick together be becoming unusable. If your the type fit and literally forget tubeless full stop isn’t for you
guys can you please let us knwo which tapes are not good and which are good to be used with it - there are many reports of tapes being "eaten" by the sealant
I've been interested in tubeless, but was overwhelmed with sealant brands. Now im more interested knowing Silca has their own sealant.
Is there potential for the carbon fibers to cause irritation to human skin if contact is made? If the fibers are stiff (like glass?), it seems that they could enter the skin, like fiberglass insulation? Just wondering how this works. Thanks!
Were you planning on washing your hands with it? Lol. Just wear gloves if you think it will be messy for you....no?
@@HolmsOnBikes actually, I was going to try it for contact solution. Hah! Yeah, gloves are a good suggestion. I'm hoping to hear from Silca on this one.
The carbon is coated in latex, so you have to work pretty hard to have direct contact with it. We have to take significant precautions in the factory when mixing the raw carbon into the sealant, but once it's in there, it's no big deal.
Any test on getting the latex of your clothing afterwards ? i have ruined so much clothes from puntures.
Sorry, but latex is latex.. but you can uses latex paint remover which is available at most hardware stores to get it out of clothing.
@@SILCAVelo and it wont damage the clothing ?
Now... do you have a distributor in europe?
We have dealers and distributors across Europe you can find them here: silca.cc/apps/store-locator
How realistic is it, to get a 6-8 mm diameter puncture?
Is there any ammonia in the solution?
No ammonia!
i started running gp5000 clinchers with latex tubes with latex sealant in them last year with great success: zero punctures since. would this sealant work with this setup as well?
You can use the replenisher in latex tubes with great success, but you cannot inject the Ultimate sealant through the valve, so it can't be used with latex tubes.
How does this compare in regards to rolling resistance to other brands?! #marginalgains 😁
Also could you use Stan’s as a replenisher in a pinch?
Sealant rolling resistance is all about how much you are using, no real differences between brands or chemistry.
Tell me difference between putting 2oz. Of Ultimate tubeless sealent Every 4months or adding the Replenisher in my 32mm tire?
Ultimate sealant cannot be injected through a valve, it will just plug it. So the replenisher allows you to refresh the sealant through the valve without having to unseat the tire. Also, the amount of carbon fiber doesn't need to increase from the initial install.. the sealant will begin to evaporate, but the carbon stays, so you really just need more liquid and not more carbon.
I'll bet it seals holes really well, but I'm wondering about the materials safety if the guy in front of you has this stuff in his high pressure road tires, he punctures and then you breathe in little bits of carbon fiber. Also, I'm not all that keen for bits of carbon fiber to find their way into waterways. Any comments @Josh?
Couple things, the carbon is so good at plugging the hole that none of it really ever gets through, we've punctured hundreds of tires with this stuff and at most you get some oozing latex. Second, this is pyrolized carbon fiber, it is chemically identical to activated charcoal which is used in water filstration and has no adverse biological effects, is not considered a contaminate to water or anything like that. If you were to grind this carbon into a powder, it would be nearly identical to the carbon black that is used in your tires or your shoe soles. The carbon is also fully encased in the latex, so any escaping sealant is just carbon and rubber, nearly identical to that skid mark you leave on a rock or pavement.
@@SILCAVelo thanks for your answer. I think other people will be asking the same questions.
does this work > 80psi
Compatible with tire inserts? (i.e. Vittoria)
Yes!
@@SILCAVelo Have you guys tested with various inserts? I.e., are there inserts that you would avoid and those that you would recommend (if not by brand but by characteristics)? Thanks.
I'm interested if this will finally replace Orange Sealant (it is not possible to get it from where I'm from)
How well does it work under rider weight + high pressure for road tires?
Better than Orange Seal, the carbon fibers form a high strength dam behind the hole allowing it to work at much higher pressures than most sealants.
well something plugged the holes hmmm.....stick a camera in the tire, someone did to a car tire, pretty interesting
What plugs would you recommend if a puncture is NOT sealed?
Check out Sahmurai sword or Sahmurai switchblade
How does this react with CO2?
All latex based sealants will be degrated by CO2.. if you need to use it then go for it, but we will have similar issues to other brands over time with CO2.
Michelle really blew it with the close up shot 5:41
Hey Zach, this is Michelle and yeah...looks like I forgot to blow that up for you! My apologies and thank you for pointing that out. If you are interested, you can check out the image on this page: silca.cc/pages/ultimate-sealant
@@SILCAVelo thanks! Just giving you a hard time, no hard feelings. But you got me to click to the website so good job there!
I think Cafe Latex efecto mariposa make the same thing but they start maybe 10 years ago and the results are at minimum debatable
They were the first we know of to use a surfactant, but they missed the other parts of the formula that make it effective.
@@SILCAVelo ok thanks for the explanation. Regards
At the end of the video; was anyone else tickled to see the focus lock on the beautiful Masi in the background???
Sounds like this will be the go-to Sealant.
If I use soapy water to seat the tire, will the water and soap ruin the Sealant?
Also, do you need to add the refresh to replace evaporated Sealant liquid or does that add say 2 ounces the the weight of the tire/wheel each time?
I would avoid using soapy water with any sealant, I believe there are some bead lubricant products out there that are wax based that should be safe. Good news is that the industry is getting its act together and we are seeing improved fit up of tires and rims each year so hopefully you won't need this method forever!
They didn’t put the thing right there
my tire last MAX 2 months...
Glue 😇
I had a bad result with this product, after fitting the tyres according to the installation guide I found the product “set” inside the tyres and put the wheels out of balance, cleaned everything up and tried again but same result…. Product seems to dry out very quickly….. got nothing productive from Silca and nothing from the retailer… Back to Stans Race as I know it works and doesn’t dry out in a couple of days and throw my wheels out of balance and I know its still liquid cos I can hear it sloshing around.
I have now watched the entire video, as the title has made me very curious. And I am shocked at the audacity with which SILCA are trying to portray the sealant as a pioneer on so many levels.
1. "Fiber Foam": Effetto Mariposa already tried this " innovation" with the foam a few years ago and it failed. Why? A foam can transport individual particles, that's true. But the problem is that these few particles/fibers are not enough to seal a hole. What works much better is if all particles always stay homogeneous in the liquid. This is for example what MucOff, milKit or Peaty's do.
2. Ecological Aspect: As far as I know the only supplier that currently still uses natural latex is Stans (because they simply haven't developed in 20 years). To stabilzie natural latex you need ammonia which corrodes the rims and spoke nipples, is harmful to the environment, smells horrible and is no longer allowed to be used for Maxxis tyres for example.
3. Longevity: It may be that the sealant in combination with the refill bottle is good for over a year. But that certainly does not speak in favour of the Sealant if it requires this additional bottle.
Great to see that you joined RUclips today in order to leave this comment, but it's fundamentally flawed in numerous ways:
1. Effetto Mariposa continues to foam, it's what makes it the best sealing synthetic latex sealant on the market, we credit them with this innovation in our media launch materials. The current version foams less now than the original formula, but still foams. Your assumption regarding MucOff, Milkit, and Peaty's is also not true, the plastic particles generally centrifuge out and stick to the casing while riding.. we punched hundreds of holes in tires with all of these and you will almost never find one of those particles flowing into the puncture, they just aren't mobile enough when riding, all of those sealants also just don't work that well and are full of micro-plastics.
2. Uhh.. this is far from accurate, more than half the brands use natural latex and Finish Line just replaced it's poor performing synthetic latex with a natural one that supposedly works much better (according to them not me). Testing over 30 brands of sealant, the natural ones pretty much all work better than the synthetic ones. There are also non-ammonia methods of stabilizing it, though it still doesn't smell good.
3. Our longevity for the sealant is comparable to Orange Seal endurance or original Stan's, and with the replenisher can be extended considerably without having to replace the entire sealant. Over time, this means using less sealant not more.
Unfortunately like everything silka it'll cost a new bike
Dude, people are busy - way too much babble.
So disappointed, after viewing the Silca videos and reading mostly positive reviews, I wanted to try the Silca Sealant but after a difficult direct-into-tyre installation my first rear tyre puncture failed to seal or hold any pressure. It also sprayed a significant amount of sealant over the bike which was a pain to remove and clean. I had high expectations for this product but will not use it as I cannot rely on it at all. Sorry Silca, over priced and over hyped.
Go back to the drawing board, I tried it, and it sucks. Absolutely worthless.
Josh! 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
Sorry for your valve clogging experience, but this is factor for all sealants of all brands and not just ours. A quick google search finds thousands of articles and forum threads on Stan's and Orange seal and all the other brands clogging valves and how to fix or prevent it. Our method is to coat the valve core with Synergetic or similar wet lube before installing and to put the valve stem at the 4 o'clock position for a minute before pumping. You can also spray a little wet lube into your pump chuck which will keep any sealant that escapes from hardening.
Does it clog the valves in normal usage? (not filling them but airing them)
No
