Nice one, this was the test which most others missed. too many previous tests focus only on the ability to seal the holes. I will save you the effort of testing Cafe latex ( I have used it for over a year but its not very good. It is ineffective in sealing a 2-3mm edge of tread hole during a race, plus it dries out completely within the tyre in 3-5 days. its also really hard to remove from the inside of the tyre after it has dried. Hardly any reviews test the sealants after a week of riding+ the bike being stationary, by which time many of the options available look like they will have become solid, often in one area of the tyre they are then ineffective.

I'm sure Doddy from GMBN would have a field day watching this video.

Very nice comparson =) And for all who like to know how Schwalbe Tire Sealant would work: It is rebranded version of Stans No Tubes, means it is the Same. So i use it regular and like You said it is very good!

Great video!

Which was the best? ! 🤔😕

I agree. Not to mention the amount of products. Even if he purchased half of these, it must have cost a lot.

Would be good if there were a bike ride with the good sealants then check the pressure

It all depends on the tyre youre using no?

@@soulboken4670 no. All tires have a life, and it is by time. Rubber naturally deteriorates being ridden or not. Even if they sit there in controlled conditions. If you maintain and keep fresh tires, this method is likely just fine. However, I never realized the "dry" nature of the actual cords themselves would soak up the fluid. May do that when having a puncture, causing imbalance, and a weak spot. I am planning on converting to tubeless this weekend for both my wife's bike and mine. Going to try dry first, and see how far out we can get and probably have a flat! Lol! I hate the idea of fluid in the tires, and as a mechanic, with viscous loss as it rotates, and imbalance, not to mention, rotating, viscous, drag generating weight. Guess these sealants are used widely for a reason, I'll find out the hard way likely. Think I'm going with the Stan's sealant myself, if I must. I'll report back either way.

@@georgesrisomsak9650 Hey, report back.

@@javik3995 haha! YOU NEED SEALANT! 🤣 IT IS INDEED NECESSARY!

@@georgesrisomsak9650 The hard way is that fun?

I used cyclon repair gel which is the same kind of foam on a ride where I got a flat and the sealant wouldn't close the gap. It actually did the job very well!

Was it *"FlatOut"* Sportsman Formula with Kevlar fibers? [Used to be known as MultiSeal] I use that on my eMTB and Travoy cargo trailer, seems much better than the other kinds.

He recommended it. Pay attention.

I added more Finish Line Sealant and the small puncture wouldn't seal up very long. Would coat my seat tube back with it. it was hard to see the hole too.

I think these work well: www.prestacycle.com/products/

Try putting glitter in with the sealant or just use orange seal

I mix stan's with finish line. A little expensive but good results.

remove the core, use a 2mm allen key and pierce it through., reinstall the core and pump it up.

I always use plain old slime

who gives a dam about engineer jargon, we know what he means ed-u-ma-ca-ed sub. Great job Danny!!!

Stick with plain old slime

It doesn’t matter, the pressure will increase proportional to the amount of sealant because it effectively makes the cavity inside the tube smaller. Pressure is pressure and is determined by the size of the vessel not the contents. Just fill it to the recommended levels and don’t worry about the slime.

Yeah . Not so bright there buddy . It will have less air due to the sealant taking up space . And pump it to the pressure you had before . It just takes less pumping and air volume . But still needs to pumped to the correct amount of pressure.

About 29 PSI ;)

Hahahaha. Best comment I've seen in quite some time. Legend.

Stan's

Simson kit works best but takes time. And if you get the bike home ofcourse.

It works great, sealed a tire that stans wouldn't and it lasts much longer. The regular orange seal works even better but dries up after about a month and a half

@@sturdyvw are u able to use that stuff in tires with tubes??

I have the same question. Hope you get an answer.

It depends on the tire and rime. most tires now are tubeless-ready but not all rimes. It should be written somewhere on the product.

@@zach.225 my rims have a sricker that says tubless ready. Is a 2017 Giant Trance 4.

@@CRGT666 Then you should be good, I think.

Dear Trippin, here is what I wrote to Danny as a warning about the dangers of converting normal tire to tubeless... Hello Danny, I take it that is your name. Anyways, you mentioned that you have converted non-tubeless tires to tubeless using Stans sealant. Unfortunately doing so is extremely dangerous as the tire can suffer catastrophic failure, causing injury or death. For 20 years I developed bike tires and tire making machinery for major Asian brands. I did a lot of tubeless testing. You see tubeless tires have a layer of tube rubber inside to hold air better and seals the more porous tire carcass rubber. The tube rubber also prevents any type of sealant from permeating into the more porous carcass rubber. What happens is that in time the porous rubber begins to breakdown and becomes more porous usually down the center making it easy for the sealant to permeate thru the rubber. This permeation then begins to accelerate and damage the tire carcass right down the middle of the tire. At some point, the sealant reaches the cords and the cords act as a drinking straw making the center of the tire soggy and very weak. Finally and usually at high speed, the tire rips wide open at the center usually with a 6" ~ 9" inch gaping tear. I would advise not to mention this kind of practice.
