Sealant into road tubes

[MTB_Roadie]

Sorry Tank Man I am happy to reply I just did not realise that your reply in can tubbies be repaired thread was a serious question. Please see testimonial from one of my clients below on his experience with a Tubbie and in his MTB

 

Hi Jennifer

 

Would like to take this opportunity to say thanks for the great product that you guys have. I have been using the sealant in my MTB for about 18months now and can honestly say that it has worked perfectly.

 

Toward the end of last year I got a few punctures on my road bike, which was very frustrating. So I decided to put NO FLATS in my road tyres, can honestly tell you that is works just as well in a road tyre as in MTB. I did get punctures but never had to stop and change the tube, all that happened was a slight loss of tyre pressure, I run my road wheels at 120psi, the pressure would drop to 80psi and I could continue riding. Because the sealant worked so well in my training wheel I have subsequently put some in my racing tubbies as well. This was a life nfrustration saver, the last time I went up to Nylstroom we went out on a long ride, on which I used my tubbies. About 20km into the ride I picked up a puncture, it was however not necessary to stop as the NO FLATS sealed the hole and I was able to finish the 160km ride without stopping to change the wheel or to inflate the tyre. Upon getting home I checked the pressure to find that it was still 100psi.

This has given me the confidence to use my tubbies more often.

 

I can highly recommend that any person can use NO Flats in both road and MTB wheels, it will most certainly save much frustration.

 

Cycling greetings

The above testimonial is from a client from a reputable shop but I do not want to put his personal number here for the world to see. But please feel free to PM me if you would like his number to confirm this testamonial.

 

I think that your suggestion of testing in a backyard with a hammer and nail is ludicrous. The real test of any sealant is in the field and on the track in normal riding conditions and with normal hazards, I don't know when last I got chased by a guy with a hammer and nail when I was out on a ride( now that clip would make it onto Leon Shusters next video or Whackshead pranks) I will stand by my product but I would not go against the laws of physics by puncturing any tyre that is at 10 bar with a nail. With our product you need to be on your bike as your weight movement and heat all play a part in the sealing process of my sealant.

 

Our product does not work like any other product in the market in South Africa today

So Tankman if you want a serious answer to a question then don't ask a stupid question.

 

Okay....so you cycle over a nail and it punctures ur wheel at 10bar....I however did manage to hit a nail the other day that even got stuck in my tire......put a nail on the floor, cycle over it and show us what happened.....then weight and everything will be in order....

 

I think his question was valid....no other sealant worked so far....so prove now urs does...

I do not disagree with you or tank man. The tone of Tank mans reply is what made me not take him seriously.

Our product will seal a puncture caused by a nail, and I have a number of testimonials to prove that my product does indeed work.

 

I would be happy for anyone to test my product. I just feel that putting sealant into a tyre and then taking a hammer and nail and puncturing the tyre is unrealistic.

Why is it unrealistic?

 

All punctures i had with my road bike were from nails,screws,glass or potholes.

 

Lets see a video of your product sealing after a puncture with a thin wire or thin nail @ 7 bar.

 

I have tried many sealants on my road bike and nothing seals 'till about 3-4 bar and then still runs out.

 

I will give sludge a try and NOTUBES when i am in SA.

 

You will make a fortune if this seals @ 7 bar like claimed.

I agree that that punctures can be caused by nails, glass ect, I would be happy to make a video, my issue with videos is that a person can put any amount of product in a tyre and then puncture that tyre and it will seal.That then gives a false impression. What I am aiming to do is to get real people with real bikes to test my product and give me testamonials. It is the only way to insure that the truth comes out. In a mountain bike you can puncture the tyre as seen in the Joes video that is not an issue the issue comes in with a tyre at 7 bar pressure.

 

Again I would like to say that any video you see of a bicycle tyre being punctured, the question should be how much sealant is in the tyre, and will it still be as effective in a few months time.

 

Videos can be altered and edited to suit the product (not that I am suggesting any sealant has done this)

Listen here lady, I do not post anything but serious statements on the hub! We wont be discussing sealants for a week for the fun of it.

 

A question ends with a question mark. Do yo see one here where I challenged you to prove the worthiness of you product? (that was a question) I was only being polite in using the word please, dont confuse that with a question.

 

Please put your money where your mouth is and prove this by making a video and posting it here. That way you will promote you product and I will even buy some from you if it works.

 

Pump you tubby up to 12 bar

Take a nail and aim it at the tubby, take a hammer and give it a good whack.

BOOOM - ... blowout that no amount of sealant will stop!

 

Now wipe the sealant from your face and post that video!

 

This next post was not a question either, it was an instruction, again in a polite way!

 

Jennifer could you please explain to me how your sealant is going to fill a cut like that using laymen's terms or scientific terms.

 

One testimonial from one guy, bike shop owner or not, means absolutely jack all!

He was running his tubbies at 120psi, the rest of us run at 160 to 170psi except Edman

 

I have read through the testimonials on your web and none of them gives great insight or does a proper test of you product.

The only one worth reading was the one from Fritz Pienaar Cycles and that mainly points out that too much of your sealant is required to do the job correctly, making the tire heavy. And guess what? They ONLY tested tubeless mtb tires, no mention of tubbies anywhere!

 

There are two examples in the thread of busted tubbies.

HERE IS MY QUESTION:

How does your product work? How will it seal cuts of this size when no other sealants claim to be able to do so?

 

Here are those two examples again:

 

After you have answered those two questions we can discuss the whole avoid riding over nails scenario (there is actually a video of one of you competitors doing exactly that!)

A syringe will not work. The sealant will "seal" causing teh syringe to block.

A syringe works fine, been using the same one for a few months now with Joe,s.

To end this debate. There is no sealant that I am aware of that will seal cuts like the ones shown in the pictures you provided, mine included. However I belivev my product will seal punctures (not large cuts) when installed in a tubbie, that was my statement. I will get you your video. Have a good weekend.

Dear Jennifer

 

If you feel you have provided sufficient evidence to instill trust and faith in your new and unknown product to this potential market on the hub and you want to end this debate, that is your call.

 

Since you havent answered my first question on how your product works, which perhaps might have also covered, if your product can not seal cuts like in the photos, then what is the biggest size puncture/cut it can seal? I guess we would have to keep guessing since I am not buying a product just to confirm my suspicions that it will not work in tubbies.

 

Oh and you did not say "my product will seal punctures (not large cuts) when installed in a tubbie"

This was your original statment:

I happen to be the owner of No Flats Tyre Sealant, and I can tell you that my product works in tubbies and under the pressures associated with tubbies.

 

That is quite a bold statement which you havent backed up yet?

 

You also want to prescribe the conditions and psi at which the puncture occurs? Ok don't hit it with a nail and hammer then. Put the nail in the tarmac and ride over it .... it will have the same consequence as per my original prediction.

 

but I would not go against the laws of physics by puncturing any tyre that is at 10 bar

......the issue comes in with a tyre at 7 bar pressure.

 

If you dont want to go against the laws of physics ... then don't claim something that is not true.

The laws of physics prescribes that under the amount of pressure associated with tubbies, more often than not the tubby will cut, tear or burst! Not get a little 0,75mm puncture in it. And this is the point I have been trying to bring across all along, neither your sealant or any other can handle the pressures associated with tubbies. It might seal the odd small puncture but tubbies dont get small punctures very often!

 

I run my tubbies at 11.5bar or 165psi. That blowout in the photo occurred on Killarney race track, you cant ask for much better conditions than those, no pot holes, no glass but it still happened with a bang and a big cut!

 

Edman was running his at your prescribed "should be able to handle 7bar", far below the norm, pressure and still the cut in his tubby was around 7mm.

 

Perhaps I should change my second questions then:

How does you product work? (still waiting on this answer)

What is the size of the cut your product can realistically seal in a tubby run at 11.5 bar?

 

Thank you and enjoy your weekend as well.

WHAT IS NO FLATS TYRE SEALANT AND HOW DOES IT WORK.

 

NO FLATS TYRE SEALANT is a special blend of more than 25 chemicals in a viscous liquid state which coats and clings to the inner wall of the tyre. NO FLATS TYRE SEALANT is a permanent puncture preventative/repairer and a tyre life extender/conditioner, and we believe the only product on the market today that is guaranteed to last the legal life of the bicycle tyre.

 

WHAT MAKES NO FLATS DIFFERENT TO TYRE SEALANTS THAT HAVE PROVED NOT TO WORK?

 

Technology! Sealants have caused many problems that we at NO FLATS TYRE SEALANT have addressed. Using a highly evolved mixture of chemicals, we have devised a product that is more than capable of working in harmony with today’s modern bicycle tyres. We have included a patented thixotropic emulsion that bonds the molecules of the product together. NO FLATS TYRE SEALANT contains thin strands of coarse surface synthetic fibres that are stronger than steel when they interlock tightly together, but will only positively repair small holes caused by puncturing, but only a hole that is in the tread area of the tyre, and that it is shrinking in size because there is no cord damage (rubber recovery), which is 95% of today’s punctures.

Anything bigger, or in sidewall, with or without cord damage, and the NO FLATS fibres just slowly bleed through the hole, giving a controlled deflation which prevents damaged rims, and helps the rider maintain control and possibly enabling continuation of the journey to remove the bicycle from a possibly dangerous location situation.

 

NO FLATS TYRE SEALANT is not a get you home product, it is applied before the puncture occurs, and permanently repairs puncture after puncture in the same tyre over and over. Once installed, NO FLATS TYRE SEALANT not only repairs punctures, it conditions the inner casing, preventing porosity leaks caused by tiny holes and cracks. In other words after installing NO FLATS TYRE SEALANT the tyres maintain correct air pressure and the need to regularly top up with air is virtually eliminated, and with correctly inflated your tyres will also run cooler eliminating that killer problem of devastating heat build-up. Tyres treated with NO FLATS TYRE SEALANT last up to 30% longer. NO FLATS TYRE SEALANT is water based for easy clean out if ever you need to do this.

 

NO FLATS TYRE SEALANT has the unique ability to coat the entire inner surface of the tyre and rim without succumbing to the shear stress associated with centrifugal force that is created with a high speed rotating tyre.

 

Once installed NO FLATS TYRE SEALANT has been installed, it will lay dormant at the bottom of a tyre until the bicycle is ridden. Once ridden over a distance of at least 8km, NO FLATS TYRE SEALANT disperses throughout the inner air cavity and forms a coating on the entire inner surface of the tyre.

The flexing tyre and the normal heat buildup will allow NO FLATS TYRE SEALANT to seek out and eliminate common air loss problems (refered to as air migration and bead leaks). NO FLATS TYRE SEALANT then transformers the tyre into a sealed air chamber, capable of maintaining proper air pressure.

 

The advanced technological sealing capabilities of NO FLATS TYRE SEALANT stand on guard, to seal punctures as they occur. When a tyre is punctured, NO FLATS TYRE SEALNT coats the surface of the penetrating object thus preventing air loss. When the puncturing object is removed, the rubber recovers and the wound immediately closes. Any escaping air will siphon NO FLATS into the wound. The fibres begin to entwine and create a clot to prevent any additional air from escaping. As the rubber recovers, the wound closes and the strength of the tyre hold the repair in place. The specialized polymers and fibres form a clot, producing an airtight repair. Once exposed to the atmosphere, the repair begins a systematic chemical cure( another proprietary attribute for our R&D team).

As the repair cures, it makes a permanent repair that is impervious to water, which protects the inner casing from the outside contaminants.

 

NO FLATS chemical formulation, one of our closely guarded secrets allows NO FLATS TYRE SEALANT to withstand heat and the shear forces created within a rotating tyre.

 

WHAT IS TYRE FLEXING?

Tyres are constantly flexing when being ridden. The weight of the rider, the irregular surface of the road and the turning of the tyres creates a substantial amount of flexing. It is important for the NO FLATS repair to be forced though a wound. Once this is accomplished the repair cures and becomes a permanent seal.

 

NO FLATS TYRE SEALANT WILL NOT HARDEN INSIDE YOUR TYRE.

People often ask “if NO FLATS cures from exposure to outside air, then why doesn’t cure by the air inside of the tyre?” As the bicycle is ridden the temperature of the tyre increases, a portion of the liquid base evaporates within the air cavity, as the tyre cools, the liquid condensates back into the formula. The inside air actually becomes part of the system. The sealed air chamber prevents outside air from entering or inside air from escaping.

 

 

SEALING CAPABILITIES FOR USE IN TUBULAR TYRES.

Due to nature of the cycling game, each time you get a puncture the circumstances will differ. Due to this fact, we do not have a set in stone guideline on the size of puncture our product will seal.

Over the past couple of years we have supplied riders of tubular tyres with sealant and have not had a single complaint that our product does not work in their tyres. Due to human nature and the fact that we love to moan, this indicates that our product does in fact seal punctures.

 

Final note:

My apologies if this reply seems long winded, but I wanted to supply you with as much information as possible.

 

I don’t want to pretend to be a cycling expert as this is not the case.

I am a business woman that supplies a product to the cycling industry. My R&D team are in the process of complying relevant information, testimonials and (as of Tuesday) a demonstration video describing the benefits and attributes of my product.

Please allow me the time to put all this information together in a professional and orderly manner so that it meets your satisfaction.

Please note testing will be carried out by individuals whose technical background cannot be disputed.

Dear Jennifer, based on your posts here, I am unconvinced in your product. Mostly due to your apparent lack of technical knowledge. Please can you, in your own words, explain to us the difference between tubeless and tubbies as use by the cycling world.

Difference between Tubbies and Tubeless tyres in my own words

Conventional tyres (aka clincher tyres) consist of an outer tyre (casing) with a U-shaped cross section and a separate inner tube. The outer edges (beads) of the tyre hook over the edges of the rim, and air pressure holds everything in place.

Tubbies are basically different than your average tyre due to the fact that they don’t have beads and the two edges of the tyre are sewn together around the inner tube.

A tubeless tyre is basically a conventional clincher type tyre without the inner tube. Instead special rim tapes are used to seal the rim.

I hope this demonstrates my knowledge of tyres a little better than what I have previously put across. I don’t want to pretend to be a cycling expert as this is not the case.

Just a question, If the sealant can go through a syringe how can you rely on it to stop a puncture.

 

Well it seems to work pretty well. Can't remember when last I actually had to repair a puncture on my tubeless tyres. All I was saying was that a syringe works fine to get the stuff through an opened presta valve for top-ups. I don't expect it to seal larger cuts though, carry plugs for those.

[Guest Frail4Life]

JOKES ASIDE. I am not here to say any Product is Perfect, but, some work BETTER.

 

I USE " CLINCHER TUBBIES" WHICH ARE MOULDED SOLID. NO STITCHING OR PLACE TO OPEN ON THE UNDER SIDE.

Complete Tyre Bond, does NOT need any Rim tape.

Weight depending on Model, 215 gram / 330 gram.

Min / Max pressure of Tyre, 8 to 15 BAR OR 115 to 220 PSI.

 

They come standard with removable VALVE CORES, you screw the product to the VALVE and then insert it.

Yes I have tried "No FLATS", "JOES", "SLUDGE" and another, can not remember the name.

So far the best product in ALL ISSUES, small/ big, sidewall, has to MY experience been "SLUDGE".

 

NEVER has the "CUT" been SEALED within SECONDS.

I mostly use my "TUBBIES" to Race, BUT still end up CYCLING TO the RACE and back home.
