Do you prefer clinchers, tubulars or tubeless? 👇

Clinchers, I like simple old school things, that just work. And don't require a special degree to keep working

@ciaoneef Год назад

I rode a bike with clinchers for about 7 years and only ever had one puncture. Recently bought a new bike with tubeless-ready rims & tubeless tyres, but I'm thinking of switching back to clinchers because I don't like the idea of having to replace the sealant every 6 months...

@sventice Год назад

Nice video: clear, unfussy, informative. Pretty much sums up why Alex is one of my favorite presenters on GCN. I vastly prefer clinchers with tubes. I tried tubeless and didn't like them. It's partly that I like slightly higher pressures, partly that tubeless performance isn't actually noticeably better (they're really not even that much more puncture-proof), and partly that they're unreasonably difficult to get onto wheels, but mostly it's the sealant; that stuff is sticky and disgusting.

@DavidWhiteOfFleet Год назад

Small detail you missed. Tyres started off on wooden rims, as you said, but they weren't there to give you grip. Their main job was to tie the wheel together, hence "tyres", and to be durable.

@gcntech Год назад

Thanks for the fact!

@mynameisyasser Год назад

Wow, thanks

@brian3937 Год назад

the word tyre or tire appears to come from the word attire, in the sense that the wheel had been dressed in something to protect it.

@DavidWhiteOfFleet Год назад

@@brian3937 yes, there does seem to be two schools of thought about that. Although in a wooden wheel the tyre does literally tie it together, without the tyre the rim would be separate pieces of wood.

@naldridge95 Год назад

Clinchers for me but it makes a big difference which tyres/tubes you use. My current road bike I’ve done over 8000 miles on and only had two punctures, both caused by huge potholes. I have decent tyres on this bike. Whereas on my older road bike I used cheaper tyres and used to get punctures all the time. If you invest in the right tyres you shouldn’t have any problems using clinchers!

@gruanger Год назад

I bought a cheap chinese bike. The tires that came with it popped from punctures every time I road, I just thought that was how it was with road bikes. I was a complete newb. I started looking into it and realized I was just a fool. I bought some better tires on amazon and have never had a puncture since, it is crazy how big a difference it is. I am not a racer, I ride on regular roads, so knowing I can just go out and exercise without wasting time and money is way nicer than going really fast.

My punctures are either because of the piece of glass or because of bumps. I had about ten in the last half a year and couldn't imagine how changing tires can help.

@gruanger Год назад

@@PavelSavyhin I live in Arizona with thorns, glass and other sharp things literally everywhere on the side of roads. I bought puncture resistant tires that have layers of puncture resistant materials. I am not sure what it is and it makes the tire weigh more and is thicker, but I went from literally daily flats with large thorns sticking out or glass, to not a single one since

@gcntech Год назад

Tyre choice makes a huge difference 🙌 Do you ride purely on the road or are you mixing in some gravel?

@larrylem3582 Год назад

I think clincher tires comprise tube-type tires as well as tubeless tires. Tubeless then breaks down into hooked and hookless rims. When mentioning tire sizing conventions, it would have been good to note that MTB 29ers are the same as 700c (ISO 622), 650b (584) are also called 27.5, and that 26" tires (559) were the standard MTB tire size prior to 27.5 and 29ers.

@alyoshakaramazov8469 Год назад

After a lot of experimentation, I use a tubeless 30 mm tyre with an insert for long distance road riding (2 to 9 hours at a time). I came up with this because it gives me more comfort for long distance rides and has not ever needed me to repair a puncture while on the road, and it provides the most safety against a catastrophic failure. Every few months I have to top off fluid or change it out. In case of a catastrophic tear in the tire. the insert will keep the tire on the wheel (and keep me upright instead of sprawled in the middle of the road picking gravel out of my wounds) and allow me to ride on the flat tire for some time, although this has not happened in 1000 miles of riding since I switched to tubleless. I have seen the white juice leaking out of tiny holes in my tires while on the road, which would have meant stopping to repair or replace a tube in my previous setup. On a 200 km ride I don't want to have to do that because I could run out of daylight if I were to have to stop to repair. Also, the weight of the spares tubes and repair kit can be felt after about 100 km or so. I am 70 years old so weight and the amount of time I am on the road matter quite a bit. I am using a light weight tire to compensate for the slight increase in weight from the insert and the fluid, which is still less than the weight of inner tubes and a repair kit. The only down side is that the tubeless tire is quite difficult to get on an off my wheel, especially with the foam insert. I get around this problem by compressing the foam from the sides with wood working clamps, as the special tools for this job don't always work well, especially since the fluid can cause the bead to stick fast to the wheel. I won't go back to tires with tubes because I used the "call the wife to come pick me up" card too many times.

Haven't tried tubeless yet for road. Don't like the idea of spraying sealant all over me/my nice bike, and though I'm sure it's better now, too many stories over the years about it not being as helpful for narrower, high-pressure tires. Made the switch over a year ago on my commuter/gravel bike and I love it. Less flats to/from work and more comfortable on the crappy roads I have to ride on. That bike has fenders pretty much year round as well so no worry about sealant spray when there is a puncture 🙂

Hi Alex, great video and well presented👍.

Dunlop did commercialise the pneumatic tyre though and it became the global brand we have today.

Clinchers for me, tubeless are ok when set up properly but problematic, and messy, when you have a puncture too large for the sealant to seal. I've been using 28's and 30's lately. Tried to get some more at the local bike shop today and they only had 25's - heaps of them. The mechanic said no one was buying the 25's and the 28's and 30's sold out.

Tubeless is only hard to maintain when you don't know how. It was hard for me at first but it was because I was using giant gavia ac1 tires which is so hard to seat. After going to gp5000s, everything was easy. You just need to check the sealant level every 6 months.

@richardknights2307 Год назад

Hi what would you say is the best tyre tube combo for a average rider on a set of hunt clincher wheels?

@JMcLeodKC711 Год назад

Alex, great video. I was wondering if you could settle a debate I have been having with a fellow rider. On some tires, the manufacturer will stamp/emboss a rotation arrow into the sidewall. I argue that it is critical that you mount the tire based on this. My friend says otherwise. Also, I have seen some tires that do not have a rotation arrow stamped in. I assume these are symmetric.

@gcntech Год назад

Hi John. Yes, directional tyres must be faced in the correct direction, otherwise you won't be getting the benefits of its construction in regards to grip and rolling resistance. Tyres without directions however are usually cheaper and it won't matter which way you put them on.

@bateriayvr8988 Год назад

Wouldn't mounting a tyre that has a directional arrow backwards basically be a major loss of speed? The rolling resistance on that must be huge, given that the tread pattern is intended to give the best forward momentum going in one direction! That would be so counter-intuitive LOL

@GCNalex Год назад

Hey John, thanks for your comment. The rotating direction will help the tyre work at its best and its how its intended to be used, however i must say i have never been able to notice a difference on the occasion i have managed to get it wrong. The majority of performance comes from the rubber compound and the pressure.

I didn't care, it was on a training set of wheels and other than my ego being damaged, I didn't really care. I carried nothing with me other than a very small multi tool. No pump, nothing. And, I didn't ever think about hitting crap in the road. It was really enlightening. But, the performance irked me, and the rough ride. If we get there, sold, take my money.

Thanks Alex. Is the sealant in tubeless for the rims, puncture protection or is it the spoke holes? Do we need special rim tape for tubeless? Re your question, 4:05 you talk about width, I didn't get the clue. As for winter tyres, the critical measure is the transition temperature for the rubber, ie the temperature below which it is solid and not flexible. Foe car tyres I have found Pirrelli far too "summer" for a UK winter and maybe why so many cars end up in the ditch. More geekie stuff please Alex (or are you really Bob in disguise?).

@spinnetti 7 месяцев назад

It occurs to me, that given the rims for "tubs" are a lot lighter than clinchers, why not combine the best of all the designs? Do a sealed tire with no tube on a tubular type rim and a bit of sealant (glue on I presume).. would have all the advantages of sewups, but even lighter. I guess that's what hookless attempts to achieve which has the benefit of no glue and lighter than clinchers but easier to repair than sewups. hmm. I think I just talked myself into hookless lol. I also learned from this that 1 bar does not equal 1 ATM bafflingly. 1 bar is 14.5psi whereas 1ATM (seal level at standard temperature) is 14.7psi.

@genewhalen9264 Год назад

Is there a maximum ratio between internal rim width and maximum tire width?

@itsalldownhillfromhere7932 Год назад

All I can add is that when you Max out tyre pressure and you still get deflection because of the narrow rim, you've gone to far lol.

1:10 Wait. Didn’t you [GCN Tech] say in an earlier video that solid (steel/metal) tyres/wheels have lower rolling resistance than pneumatic rubber ones?

@savagepro9060 Год назад

In case you're thinking Dunlop was a certified mechanical engineer, he was a practicing vet! Imagine he tried embalming fluid as sealant before settling for air!

@davidebaso6994 Год назад

It's not clear to me though if switching between clinchers, tubulars or tubeless is also going to change the actual performance of the bike. Do one type go a little bit faster than the other?

@johnwestwell2241 Год назад

Most pro teams have switched from tubular to tubeless in the past two seasons as they feel there is a slight performance advantage - tubeless tyres are reckoned to be slightly faster, and being able to be inflated to lower pressures, more comfortable. However, the big advantage of tubs was the ability to continue riding on a wheel after a flat. The tub would remain stuck to the rim and would allow the rider to keep riding, albeit slowly, until the team car could get to them. With tubeless, that isn’t really an option.

@departurexx1520 Год назад

@@johnwestwell2241 False, most pro team force to use tubeless because of sponsors not because of performance. Tubular is still the best performance tires. Tubeless tires are heavy AF. If by choice, GC rider will rather ride on tubular than tubeless.

Does the sealant in tubeless tyres freeze when it’s transported on a plane? Will this be a problem? @gcntech

@onehourmusicbc Год назад

It's probably not gonna freeze. But it can become solid if you keep it in the same position for weeks. It is especially a problem with the valve.

@MrLuigi-oi7gm Год назад

@@onehourmusicbc Good point, One Hour. Totally depressing when get a puncture on the road with tubeless and lose enough air before it seals such that you must add air to continue. But you can't because the valve had become totally clogged and useless with crusty sealant. Time to pray 🙏 you are riding with someone who brought an extra valve.

@simonm1447 Год назад

The aircraft cargo hold is not directly heated, but it's not freezing there since it's part of the pressurized fuselage. Animals are transported there too.

We think we would have listened more in school if that was the case!

@zeemon9623 Год назад

Calling the tyres / rims 622mm (or whichever other size it happens to be) is objectively the best way to do it. It always corresponds to the actual measurement and is the easiest way to see what is compatible. But it can't be that hard to get people to use the proven superior system of measurements. People will quickly adapt the most logical and easy to understand system any second now.

@dominikgraf7287 Год назад

A friend of mine doesn't believe that an inner tube can effect the rolling resistance. He claims that with the tyre on the outside the inner tube, like a latex one or so, can not reduce the rolling resistance. And to be honest I struggle to explain it to him. Can you help out? #askgcn

clinchers. Thinking of others on the club ride. Don't like getting sprayed with gunk, so don't want to do the same to others. Plus replacing a tubeless tyre is messy.

Is "29er" the same thing as 700?

@simonm1447 Год назад

Yes, it's using the 622 mm rim like 700 of 28 inch. The 29 refers to the outer tire diameter, which is bigger if the tire is wider. 27,5 inch mountainbikes are using the long existing 584 mm rim (also known as 650B) and 26 inch MTBs use 559 mm rims
