Road bike wheels can be inflated using a number of different methods. Butyl inner tubes, TPU inner tubes and tubeless sealant are the most popular ways of doing so, but which is best? What is the best way to inflate road bike tyres? Well, Sam Gupta has tested all three methods to work out what's best. Each has benefits and drawbacks, so Sam identifies what they are and what the best use cases are for each different type of inflation.

I switched from tubeless back to using the TPU tubes. I know everyone loves all the benefits of tubeless, yet those nearly imperceptible improvements come at a cost. Tubeless are awesome right up to the moment when they are not. Please do a "real life" video covering the efforts to get a tubeless tire on the rim and inflated compared to a standard tire/tube. You might be lucky and get it all to work instantly or you might spend an hour wrestling with it. And, do you need a compressor to install a tube? Finally, get a flat on the road with tubeless and then have fun putting in a tube. It just is too much of a hassle for the vast majority of road riders. Go TPU. They are quite excellent.

@LeeLee-fi7mx Год назад

I've never had to use a compressor, standard standing floor pump has always worked for my mtb and road Tubeless installs.

@MrJwmurph Год назад

I switched to TPU too after 4 years of tubeless, I struggled so much getting tubeless tires off and back on my rims that I dreaded attempting having to insert a tube at the side of the road when the tubeless system fails. I run the TPU tubes at similar pressures to when I was tubeless (78psi front, 83psi rear) so I've lost nothing in terms of comfort / grip. The clincher tire is lighter than a tubeless tire (of the same manufacturer, I use Vittoria Corsa), the TPU tube is similar weight to the sealant and then add in the weights of the tubeless valves and I reckon my TPU setup is approx. 150g lighter than the two wheels set up tubeless. I buy my TPU tires through Alliexpress and they're relatively inexpensive.

@shaunowen5829 Год назад

Tubeless above 32mm works for me,I use latex inners, on road bike 28 s and imo are superb ( apart from having to check every other day).

@shaunowen5829 Год назад

The fourth option is latex, wonder why you missed them out?

@MrAnon-2024 Год назад

Spot on. Tried tubeless, too much faff and mess. Went back to tubes and now use TPU.

@cauldron101 Год назад

I switched from tubes to tubeless. Felt great, but when things went wrong, fixing it was a real mess. I switched back to tubes. Nice and clean. I pop out the spare one and in 10 minutes the tire is back on the dance floor with a breath of CO2. Nice and clean. In the future, I might use TPU tubes, but never ever tubeless again.

@kawabus Год назад

I am a tubeless convert • Running lower pressure is just more comfortable and with wider rims you get more rubber contact • Set up has never been an issue, the hardest thing is just getting the tire on a wider rim (25mm internal) • Small punctures are self healing and larger punctures can be fixed with a dynaplug and a co2 cartridge. Very rare to need to swap in a tube.

@marktindale5647 Год назад

Also didn’t mention that tubeless tyres typically weigh a lot more than regular tyres. Oops, sorry!

@tellef70 Год назад

According to bicyclerollingresistance Pirelli is one of the slowest tpu tubes. I have tried tubeless, but returned to tubes when tpu was available

@CurtisCycles Год назад

I've not had a puncture on my road or MTB in 5 years since going tubeless so I won't be going back ever again, nothing is more painful than struggling to get a tyre of the rim on a cold, wet winters evening by the side of the road.

@truthseeker8483 Год назад

TPU tube for the WIN!!!!! More convenient than tubeless and virtually the same rolling resistance....

@secretagent86 Год назад

Laytex for me on good wheelset. Butyl on early season set…have not used tpu but i understand they are noisy…i LOVE a quiet ride. But tpu would be good spare

@michaelo6870 Год назад

For me, the clincher-TPU combination is the best way. The rolling resistance is excellent, the weight as well and in case of a puncture an inner tube can be changed quickly. Even if the sealing closes smaller holes in tubeless tyres, the tyre always loses some pressure and that can be very dangerous, especially on descents, so that in this case it is better to fit an inner tube.

@LuciTulcea Месяц назад

So tubeless is dangerous because it can lose some pressure during sealing small holes during a descent right? But how effing dangerous is a clincher and tube losing pressure suddenly and completely during a descent genius?🤦

@miketumelty8183 Год назад

The selling points in favour of tubeless, are in reality so minimal. If you have a proper failure with tubeless, you’re in trouble. Bad enough trying to get a tyre on, never mind doing that and adding a tube into the mix while stuck on the side of the road. Nightmare!

@fabianbv82 Год назад

What about including látex tubes in this test?

@mirkocelii5543 4 месяца назад

yes, other tests proved lates is >1 watt faster than TPU, so probaly even faster than the tubeless

@M3GRSD Год назад

I think I'll forever rock inner tubes, not a fan of the potential mess that is tubeless and sealant. I will try the TPU tubes though.

@trevorhill1577 Год назад

I believe tubeless is more for mtb off road. I've been 3 years without a puncture and wouldn't go back. With two tyres and wider tyres, savings can be nearer 10W and that's noticeable. Fixing a puncture in rain and thick mud after a day's riding is no fun. There's also an improvement in peformance as tyre pressures can be lower. I always carry a tubilito spare but it's got cobwebs now.

@andrewlabat9963 Год назад

Why would you use the same pressures for each tire, as different types of tires have different recommended operating pressure. Also, how much sealant did you use in the tubeless, which I love, by the way. I'm assuming the manufacturers recommendation..

@soumafan Год назад

While I don't doubt the results, the hassles of dealing with tubeless (both initially and ongoing) just don't outweigh the convenience of tubes. Yes, I get flats (slightly) more frequently, but I don't need to monitor the sealant level, clean out valve cores, deal with the hassle of initial mounting and inflation and when I do get a flat, I'm back on the road in less than ten minutes without having to deal with sticky goo and extra tight tires. I'll give up a couple of watts, thank you.

@TheCountrySteve Год назад

Is there a difference in weight between the clincher and tubeless tyres? You only mentioned the weight of the sealant, but I'm guessing the weight of the tyres is not the same

@adamweb Год назад

It depends on the type of tire and casing... gravel/offroad tires are going to be thicker and heavier than fast rolling race tires. The average tubeless road bike tire weight is 275-350 grams while Continental GP 5000 clinchers are 241 grams.

Understand why you did all 3 setups at the same pressure. Wish you did a 4th on the TLRs at the lower recommended PSI say 70PSI. You are not going to run you 28C TLRs at 87PSI as you did in the test

Question: do the 'smart tubes' purge air at a rate similar to latex tubes, or do they retain air pressure more like butyl? Thanks for any response!

In my experience TPU tubes retain air even better than butyl 👍🏼

Latex tubes are faster than TPU. Given the closeness of these results, likely faster than tubeless as well.

@johnscranton8365 Месяц назад

Can the sealant compound be run inside the TPU tube? Looks like this would reduce the mess...

@GuanajuatoUK 9 месяцев назад

Why no consistency in the quoted rolling resistance. Stick to the same number of significant figures

@theantichrome9842 Год назад

You need to add sew ups to this comparison.

@1947wdx Год назад

Why did you use different tires for the tubeless? Nothing stopping you from using the TLRs with tubes. To remove all variables except for the tube material or sealant, you should have started with butyl, the in the same wheel put in the TPU tube, then finally pulled out the tube and added sealant. As tested, you have different tires for each test, and different wheels. (meaning different bearings etc) all the delta's between test runs could easily alter the results a few watts either way.

@SrFederico Год назад

Because you would not buy the more expensive and heavier tubeless version unless you actually wanted to use it tubeless.

@1947wdx Год назад

@@SrFederico You are correct. A normal person would have no reason to buy the more expensive and heavier tubeless version if they were going to use tubes. My point is that the test is flawed due to the changing of too many parameters between test runs. If you want to know if tubes affect rolling resistance, change ONLY the tubes. Don't also change the tires, and wheels. As others have already pointed out, this video is really just an advertisement for Pirelli, so I guess accuracy in testing doesn't really count for all that much.

@SrFederico Год назад

@@1947wdx I see your point, but the results wpuld be of academic value only. It's well known that a tubeless tire with a butyl tube inside will be the worst combination possible, and even with TPU tube it will be slightly slower than tubeless. But nobody in his right mind will use these combinations. They actually did that right in the test to compare the things that are actual alternatives.

@Mikemonster2011 3 месяца назад

You just have to know that after what Mr. Pogacar said they can leave the cycling market. So tell that to that Chinese company! On the other hand we all know that there Michelin tires and then there is the rest! By the way, just don't be like GCN, they are just the worst that happened to cycling in recent years!

@Ohios1Cheesehead Год назад

How do the lightweight perelli hold air? I have some latex tunes that are light but need pumped up every week or so.

@yonglingng5640 Год назад

Latex inner tubes are porous, that's why you need to reinflate them more often. This is a compromise you must live with should you choose to stick with latex.

@christopherdavis8967 Год назад

A tubeless tire is a clincher

@MrAnon-2024 Год назад

Choose a TPU tube with less rolling resistance than the Pirelli ones used here, then reduce the psi from the ridiculously high psi chosen in these tests, and the TPU set-up will be the outright winner. Another biased/sponsored video to push Pirelli and tubeless.

@iMadrid11 Год назад

You forgot about Tubulars. Pirelli have P ZERO Velo Tubs you didn’t test.

@morellish Год назад

1/3 of a watt makes it the obvious choice if you want to go fast? That is essentially nothing.

@sjurk81 Год назад

Indeed. And: check the weight. The race is 225gr, the TLR is 295gr. Sealant (advice) from Pirelli is about 30gr making the TLR setup 325gr. The Pirelli TPU tube is 35gr making that combination 260 gr. That's 65 grams difference per wheel without the tubeless valves. Will you notice? Probably not, but neither would the tiny tiny difference in wattage.

@morellish Год назад

@@sjurk81 I'd actually prefer 65g less weight then a third of a watt in speed.

Oh my god, 3 watts saved at 40kph? That's absolutely amazing, what a gain.

@andrewmcalister3462 Год назад

2 wheels on a bike, so a total of 6 watts. Assuming someone is pushing around 300W to go 40 kph, that’s a 2% saving. Not huge, but not nothing either. Note this is a consumable, so if next time your tyres wear out you replace them with TPU/tubeless, you are not throwing out a perfectly functional but slow piece of equipment.
