Underrated comment

[@jandl1jph766]

Since I can't be bothered with latex tubes (too much faff installing them, especially roadside, and rather prone to punctures in my experience) and I seriously don't like the butyl rubber tubes for their bulk alone (carrying multiple spares of these can be a major drain on valuable space) the choice for me is basically between TPU and tubeless. Since I've often had a hard time getting the latter to seal properly on low volume, high pressure tires, I've taken to using TPU on road and gravel bikes while going tubeless on mountain bikes. My experience so far, after several tens of thousands of kilometers on both, has been that both solutions work well and are very resistant to failure if used properly. One interesting observation I've had from TPU tubes is that even if they do puncture, it's usually from some thorn or shard getting through the carcass, resulting in a slow leak rather than a pop - which gives you at least a few seconds notice and reduces the chances of damaging an expensive and potentially hard to replace wheel.

[@GHinWI]

Question on the TPU: have you had any welds fail?? Thanks

[@jandl1jph766]

@@GHinWI No, I've ruined a good few TPU tubes by poking holes and one by overpressure, never seen a failed joint, though.

[@GHinWI]

@@jandl1jph766 : Thanks! Do you have success with repairing punctures??-that seems to be an open question.

[@jandl1jph766]

@@GHinWI Yes, standard glueless patches seem to work just fine. However, those don't generally last too long at eight bars or more, regardless of the base material... On my gravelbike, that's obviously no concern and I've used patched tubes for months no problem, but on the tri rig that's something to keep in mind. It's enough to get home (or finish the bike leg of a race), though. The bigger problem is sometimes just finding the puncture - as I said in the original post, they tend to be absolutely tiny holes, nearly invisible even if you know what you're looking for. On a reasonably still day, I usually just put a little pressure in the tube and go around listening and feeling for the air leak, but on a windy day, I've found myself absolutely unable to locate the leak and had to use a spare tube to get home. Happened only once, so far, but that's really just dumb luck since I ride almost daily...

[@hughbriz]

Although latex are more hassle, they roll noticeably better than butyl. I have also found them more puncture resistant BUT only if the tyre and rim are in perfect condition. They are so flexible that the tubes can squeeze into tiny spaces around rim tape, get caught in the tyre as described and even ooze through very small holes in the tyre till they rub on the ground, that would not trouble a butyl tube. A lot to look out for there! Possibly best for race/sportive day only. And carry a different kind of spare so they can be fitted quickly. And keep your spare in a bag so it won't rub on things in your pack/pocket and wear a hole in it. Guess how I know that?

[@fastfish666]

yeah found exactly the same, if your tyre isnt 100% the latex tube is more likely to fail than a butyl one, small nick from glass fragment

[@kamigato]

Rode latex tubes last year, got my first puncture after 3700km, managed to repair it with the standard patch. However, when I got my second puncture, I could not even find it, because at very low pressure it didn't leak at all (even under water) and if you pump it more, then part of the tube balloons. After that I just installed butyl tubes again

Re Tubeless: The tyres have an extra lining compared to tube type ones of the same make, making them less supple and increasing the rolling resistance & weight. Plus you have to add sealant which adds more weight! The whole system is too complicated for the "benefits" and extremely messy when punctured as you and anyone near ends up wearing the sealant!!

Coat the latex tube and the inside of the tyre with talcum powder/baby powder. They will then not pinch on inflation. Have been using the same Silca Latex tubes for 12 months with zero punctures. Yes you can feel the difference, and I think they are the cheapest and most effective upgrade you can buy.

[@theparalexview785]

Same. I've been surprised by how low maintenance latex tubes have been. Other than more frequent inflation, latex tubes haven't been as finicky as some users claimed. Easy to install with powder. One puncture in more than a year, and that was my fault - I used my existing cloth rim tape instead of Silca's recommendation, and there was a tiny bit of debris embedded in the rim tape that punctured the tube on the rim side, not through the tire. A Lezyne self sticking patch fixed it. Much nicer rolling, especially on chipseal and rough pavement.

[@samj1185]

They feel totally different to butyl and you can run them with tubeless pressures. I'm totally happy with my aerothan, way more robust than latex and much lighter than butyl.

[@Rekmeyata]

Except for one MAJOR problem, there is no information yet when you get a puncture and you patch it with their stick on patches is is that patch a permanent patch or does the patch only get you home then you have to throw your tube away?

[@hw4075]

@@hw4075 Not a big deal? we're spending an average of $70 for one Conti tire, add in $30 for a tube, that's $100 for a tire...as much as a freaking car tire and there is a lot less material and engineering in a bicycle tire! For the record I don't buy Conti tires because of their stupid prices either! I won't pay over $30 for a tire, so I wait for sales on high end tires. The only tire I buy that does cost more than $30 is for my touring bike because that tire has to hold up for many miles while loaded and do so without getting flats...hopefully, but on my other bikes that's not necessary. Regardless $30 for a tube is insane if it can't be reused from one tire to another.

Wait until you get a real puncture! 5 -10mm at a strange angle and your stuck at the side of the road 42 mins in the pitch black trying to get it to seal and the bead of the tier has fell off meaning you have to use a tube anyway and you have you have to open up the tier and insert tube in to all that mess, if you can do that with getting your hands covered well you better than me. You’ll be looking back then let me tell you.

Increase effort = more calories burnt = more exercise per mile. As I’m riding for fitness and not to count grammes,watts and seconds, I’ll stick to whatever I find at the best price. Applying such detailed science to my ride takes the fun out of it. I guess I’m watching the wrong cycling channel.

[@stuartdryer1352]

I've tried all of them. For riding quality I really liked latex best. But you absolutely have to pump them up each time you use them, which is no big deal except on those days when you really don't feel like doing it. As for the TPU tubes, in spite of the manufacturer's claims I found them to be very fragile and I would get much more frequent punctures. Also the ride quality just seems a little bit strange to me, and the saving of a few grams just didn't seem worth it. Just for convenience these days I'm running very light butyl tubes.

[@cyclonutterd7075]

Can you explain the science behind changing rolling resistance with different tube types. I would have thought the tyres are in contact with the road and are responsible for the rolling resistance of the system, so how do the tubes affect the rolling resistance.

[@danielbum912]

Possibly not the most scientifically accurate explanation but I would say that as you pump up the inner tube and it presses against the inside of the tyre they both become sort of one system. The tube, with its own properties like wall thickness and toughness, reinforces the sidewall and tread area of the tyre, so a thicker, tougher inner tube would take away the suppleness that is considered to make a tyre fast rolling, whereas a thin, supple tube wouldn't. It's also worth noting that some of the losses can be attributed to friction between the tyre and the tube and it's rather obvious that different inner tube materials would feature different coefficients of friction, thus leading to more or less losses.

[@SaschaN]

@@danielbum912 hey Daniel, the second one is the more important thing in my opinion. If the tire rolls over the ground with pressure, the tire deforms and also the inner tube. If they both deform they rub to each other (very low like you have seen in the numbers). This friction between tire and inner tube while rolling/deforming creates some heat which is in the end the saved amount of reduced rolling resistance. Just my guess.

[@samj1185]

Sascha's reply is pretty good. In short, the tire/tube combination must compress at the point of road contact as it rolls. The stiffer and thicker the tire/tube material, the more energy it takes to compress it and that slows you down. I so very much wish I could go back to my 20 year old self and make him understand that 19mm tires at 110psi isn't the way to go. Oh well....

[@peanutboy41]

I remember when I changed from schwalbe lugano (worse rolling resistance than some XC MTB tyres) to GP4000 and latex, it felt like I had bought a completely new bike!

Then you need to buy expensive supple tiers, challenge, Rene herse and so on a tube wont make a difference in rigid tyer like a 4 season gator skin. You then will take a hit on puncture protection with it be tubeless or tube. Rene herse actually recommends to this day that if you need to use over 60psi is to use a tube, I weigh 63kg on average and I'm around 57psi on the back so very close to the tubless limit on any 30c supple tier. Tubeless tech for the road is still not ready for prime time as far as I'm concerned especially for heavier riders i have a friend that very tall and though he's skinny weighs around 180kg on a good day He can't ride road tubeless at all.

The conti supersonic (a 50 gram butyl tube) or their 80 gram version called race light 28 are priced between $20-35 CAD each. I use those. PLEASE NOTE: The use of latex tubes in carbon clinchers with a rim brake track is an absolute no-no. Keep it up @GCN Tech.

Chinese TPU tubes went down in price to around 4$ a tube, which would put them on par with decent butyl ones.

[@DamnitsAdriel]

TPU or mine was Aerothan tubes are worthless.. I've got the valve loosen after pumping since it can't resist the heat from the air pump..

[@kingelvis]

Tpu tubes are really the best thing I have bought for my bike. They can't be beaten for the price you pay for the weight savings. I would go as far as say they are revolutionary! Also the convenience of carrying a spare, means you can carry 2 or 3.

Which inner tube can I use without a tire?

[@Ohios1Cheesehead]

Watching again for then butyl shirt lol love you guys!

[@CptnKremmen]

I had a spare butyl tube in my saddle bag for a few years (no punctures in that time). When I came to use it; the wear and tear on from moving about, in a fairly tight packed bag, had wrecked it. Just wonder how robust a TPU tube would as it could be a light weight spare.

[@gaza4543]

That will boild down to how well you protect it from thing in your bag and how much its moving. Placing keys next to for example will effectively saw into it.

Definitely get that resistance is butyl t-shirt made!!

[@lenwilkinson8541]

I gave up on latex. The reduced rolling resistance with latex was noticeable, but I tired of pumping them up every single day. They would lose 5-8 psi per day. I temporarily returned to butyl but now use tubeless.

[@TheRflynn]

The rolling resistance tests seem to be done on a steel drum which isn’t real world. Actual surfaces vary widely in smoothness and this makes a difference. , Drum is probably closest to an indoor track.

[@larchman4327]

I like latex tubes the best just make sure you have a quality bike pump cause you'll be using it everyday.

[@Plasmo20]

hmmm my experience with TPU, they are far easier to live with than Butyl. Being slippery they dont catch on the rim or tyre when installing and also being smaller they sit in the rim trough better and dont try and poke out at that last piece of tyre bead is being massaged on the rim. Possibly the TPU being slippery plastic is why the rolling resistance in reduced as they dont bind to the tyres carcass when rolling.

[@davidperkins3621]

Always use my latex tubes securely encased inside a tubular - no problems with fitting them………

[@stevemawer848]

@RollinRat That's probably to encourage you to do it yourelf - it's not difficult. Easier than clinchers, though a bit more time-consuming and messy.

[@ambhetsjour-knee5370]

5th ..Nice Comparison

[@Andy_ATB]

Fastest is no good if you keep getting punctures; I'll stick with tubeless for summer, and my slime inner tubes for winter.......

[@GelMibson-u2y]

So run tubeless and carry a tpu spare. Got it!

[@Klips005]

Did anyone mention the tubolito TPU puncture test? Where regular tubes took 7 N to puncture and TPU took 17 N? Claimed double the puncture force to pop TPU? I'm running latex and really not impressed with their life lol but then again i guess they should be for race days hah TPU sounds mmm brittle so based on user reviews idk

[@bradymyers3675]

Are latex tubeless compatible with CO2 pumps? Some forums suggest co2 isn’t good on latex and break them down.

[@piffiiiiiiit]

Can someone explain in layman's terms how the choice of tube impacts rolling resistance?

[@E1huzen]

I want that T-shirt

[@raspberrylord9550]

Or "Join the resistance, Join team butyle"

[@onederment]

I happened to read the small print on Pirelli Cinturato Velo... they don't recommend very high psi when going tubeless. But with an inner tube you can inflate to 116psi... Just another thing to consider. So What goes faster a TLR with an innertube with a psi of 100 or a TLR with sealant at 87psi ? I would think that Pirelli Pzero's with a latex tube would be great. Just don't like the idea of a clincher with a high speed blow out. Been there before... I also noticed if you have a new TLR tyre then stick a butyl inner tube in it first and stretch it before trying to put a latex one in. I have ruined many latex inner tubes. Pleased for the tip of cutting it up for patches!

[@gaza4543]

People forget this fact for the heavier riders out there, most tubeless systems are limited 60-70psi mix that with a supple tier and those PSI's just aren't enough for the heavier guys.

[@MegaF1guy]

I use Tubolito TPU tubes. I love them. Great videos.
