TPU and Latex sound better when rolling across tarmac, but in my experience you get far more road buzz than standard butyl tubes with these options. I think one of the more standout differences between the tubes is what happens when you puncture. In my experience TPU deflate almost immediately, latex loses air quickly and screams like you’re releasing air from a balloon (can be quite daunting), where as butyl punctures and releases air slowly giving you time to limp to a safe stop. So put yourself in the scenario, you’re descending on a lovely set of carbon rims and puncture around 50kmph+, having those extra seconds before you start grinding away your fancy carbon hoops could be the difference between a near miss, scratch, cracked rim or even a potentially nasty crash. So on that premise I think Butyl should still be the choice of the people, but TPU and Latex certainly have their place given the conditions 👌🏻
@@sogamdok I use TPU and carry 2 spares. Weight = 100g. 4 x butyl weigh = 560g that's a saving of 460g or 1lb. That's brilliant bang for your buck imho.
10 and half minutes of video and you guys left key information out. 🙄 Latex tubes cannot be used on a rim brake bike with carbon clincher wheels. They're not very heat resistant and can fail in a carbon wheel as they do not dissipate heat as readily as alloy wheels. TPU can only be patched with manufacturer specific patches, if at all. Some brand TPU tubes have also had issues with leaks coming from the valve stem where the valve is plastic welded into the valve stem. Ask me how I know. TPU tubes also stretch when inflate for the first time. Subsequently, you can use the same tube to change from a 25mm tire to a 28mm tire, but once the tube is "stretched" to size, you may have issues if you step back down because it does not shrink like a Butyl or Latex tube.
I've been on latex on 2 road bikes for over one year and can deffo feel the difference, and lower rolling is a fact. Have to check tire pressure every ride, but I did that before anyhow, not an issue for me. They are diffidently Smoother and quieter. Have a tpu as a spare, they are brilliant for that, light and small.
Exact same set-up and it was immediately noticeable when I switched from butyl to latex. Have to be a bit more careful when initially fitting them, which is another reason why TPU are better to carry as a spare.
Solid info here, you nailed this one. I'm a latex tube guy myself. Pumping them daily is no big deal because it's so important to ensure tire pressure is correct, I always did that daily even with butyl tubes.
As a racer, I've used all three types of inner tube. And tubeless. For me, tubeless doesn't seal above 50psi. I've been stranded too many times. Much easier to get going with an inner tube setup. Latex is fast but fragile. TPU can be found cheap online and makes a cool sound when rolling. If including the spare, you'll save about 300g in weight. I'm not going back to butyl.
I run tubeless at 80-85 PSI, and have no problems. I don't race, but I do high mileage and have some fast, twisty descents in my area, so I feel like I've tested them in pretty demanding conditions. I did have an issue when I first switched my road bike to tubeless, but found that you need to be more careful with the rim tape on a road bike than you do on an MTB, presumably because of the higher pressure.
Started with butyl, then for a short time TPU, and now the last 4 years I ride Vredestein Superlight Latex inner tubes with Michelin Power 25mm tyres, this is for me the best and fastest combination.
@@comedyman112 The latex tubes make for a smoother, less 'bouncy' and therefore faster ride. That is: in my case. All bikes, wheels and tyres and roads are different, so are the results.
Switched to (Pirelli) TPU over summer, from butyl, and can definitely feel a more lively but compliment ride. Like it. No punctures yet. Cost soon forgotten. What's strangely weird is NOT smelling rubber when you let the air out.
I also switched to the Pirelli TPU this summer and you can definitely feel the reduction in rotational weight when accelerating and climbing. I’ve been riding the Pirelli cinturato velo tires with the TPU tubes and haven’t had any problems with punctures.
Traditional tubes are trivial to repair in field and a patch kit - of 50 patches and two glue tubes - will last several years. I had tubes with as many as 15 patches applied to them before I had to trash the tube. Likewise - butyl tubes play nicely with tubeless sealant ( yes, i know ), which creates double-protection against punctures - which Is great for commuting.
They completely glossed over the issue of potential new hassles with puncture repairs. Perhaps they think our sponsors will always be there at the side of the road with free replacements whenever we get a puncture?
@@redalert2834It is super easy to patch TPU tubes and they are so tiny, you can always take spares with you. If anything, TPU is better at the road side puncture repair. To be fair, I am not confident about a 16 patch tpu tube, but I never had more than 2 patches on a butyl either, because they start to feel clunky with those patches.
I definitely patched tubes like crazy before. I couldn't fathom going back after switching to tubeless though. I live in the land of goatheads. 3-4 flats a week(sometimes not even getting off my street😵💫😅) down to maybe plugging 3 tires a year. *sealant sucks in tubes. It's simply better than nothing
@@3dprintersawhiteboard401 What types of patches do you use? From what I have heard, TPU tubes are nearly impossible to permanently patch (even with the manufacture supplied patches).
@@veganpotterthevegan Years ago I lived in goat head country. I had heavy duty tubes, Kevlar liners and tires with a lot of Kevlar. Yes - I used Slime too. After I did that the flats stopped.
I have been happy with the RideNow TPU tubes. (GP5000 tires & Alpinist CLII wheels.) A lot of the roads around here are pretty rough and they've held up fine.
I ordered 6 tpu tubes last year and they all puncture within 2022. It was rough. With little hope I order the new 26grams tpu tubes from Ride Now and changed my tires from gp5000 to conti Grand Prix GT. With great pleasure I can say have been puncture free for all 2023 with this combination.
@@Mavczers I ordered 4 and they came in 9 days, I was honestly surprised on how quickly they showed up as I was expecting at least a month wait! Looking forward to running them
Ollie is building quite a trusted persona. He's a smart guy. He's passionate about technical details. He's eager to learn about product performance. He's intellectually honest. Ergo... we can trust what he says.
I’ve been using Latex (Vredestein) for 15 years now on my road bikes. I wouldn’t use anything else! Much better feel and I think my secret weapon to going fast on the flat or downhill. I carry butyl as a spare and use butyl in my commuting/ shopping bike. Would only ever consider TPU for hill climb races which I probably will never do as I’m useless uphill! Incidentally I use Vredestein fortezza tricomp (old stock), now superseded by fortezza senso. The higher TPI version not the cheaper all weather. I have not had a single puncture in 15 years due to anything getting through the tyre. The only punctures I have had are when the latex tubes age (after about 5 years) and fail typical around the valve stem or abrasion on anything sharp on the inside of the wheel such as caps covering the spoke holes which I was using instead of rim tape to save weight. Just thought I’d mention as Vredestein rarely gets a mention. Grip is also excellent (better imho than equivalent conti GP) though arguably they wear out faster. They certainly feel fast especially with latex tubes.
I just swapped to TPU ridenow tubes. Very very suprised and the weight saving is great. I just put up a review up on my channel of my first experience with them. 👌👍
switched from butyl to tpu and love it. the price is higher but if you compare it to other bike tech this is probably by far the best upgrade per $. today i found out i have been riding over 500km with a thorn in my tire and tube.
I use lightweight butyl tubes on some of my bikes. But I use tpu in the saddle bag, can fit 3 tubes in a smaller space, and carry a small tpu repair kit, just in case.
Recently switched to Schwable Aerothan 60mm on GP5000s with Roval Rapide CLX rim brake wheels. It’s important to mention that TPU can be used on Carbon Rim Brake wheels. I rode a 100 miler with TPU and had no issues. There were some rough roads and had no issues. I believe they inner tubes helped my climbs and speed on the flats.
I've gone tubeless on all my bikes now. However I always carry a spare tube just in case. TPU is perfect for this, the small size is biggest advantage. When I have used them they have been faultless and I haven't really noticed a difference from the tubeless set up. Well worth the additional cost and probably the best bang for buck upgrade you can make on your bike, even if it's just carrying it around unused.
Been riding Ride-Now TPU for over a year. Love not having to inflate every day, tiny, light, and has no need for talc, unlike Latex. Slowly converting all my bikes to TPU over Buytl and Latex. If it wasn't for ride-now, then it would only be the best bikes.
Excellent video and commentary on this topic. TPU for everyday high-performance use (and who doesn't like that) and latex on race/event day. Butyl for touring, commuting, budget, and ease of patching. They have a very long useful life.
Love this video! Very informative and helpful, I was wondering if there was something wrong with my latex tube because it was deflating overnight , now I know!
Latex tubes (green or pink), 28mm GP5000 on wide HED Ardennes rims at 38-40 psi: comfort, speed and easy to maintain. Cornering with wide rims is something you have to experience to appreciate, the 28mm and HED rims make this possible (no light bulb deformation of the tire in cornering). Great job guys, as usual. Need to come up with a new "doctor" moniker for Ollie...
I have been using the Continental Supersonic butyl inner tubes (around 50gr. with 42mm valve) since they were launched, but three years ago I switched to latex - first the Vittorias, and then to Vredestein latex (ivory coloured, and 52 grams with 50mm valve, here in Germany you can get tem already for 8,50 Euro), I also use them on my deep section carbon front wheels (62mm and 80mm DT Swiss). Although I had used the lightest butyl inner tubes available, the use of the latex was a revelation, especially on descents. The Vredesteins loose 2 bar/29psi per day (in case you pump the tyres up early, and want to use the bike the whole day, take this in account), but they are worth it. I inflate the tyres before each ride anyway (I also did so with the Supersonic inner tubes), it does not matter (and my rides last 2.5 to 3 hours max.). I even inflate all bikes regularly during winter, to prevent the tyres getting flat. It is essentially to use talkum, and to use only glued rim tape and none of plastic - it can happen that the sharp edge of those rim tapes (e.g. the light blue one of Schwalbe or the yellow of Michelin) cut the latex tubes, and be sure to refasten the valves, as most tyre companies don't attach them to strong, so it is easier to put them out in case you have to use valve extenders. As I recently had to change the inner tube of my front tyre, I saw that the drillings for the spoke nipples have quite remarkable sharp edges, at least DT Swiss should grind them away before putting on the tubeless tape (or put on two layers of rim tape, in case this is cheaper). I had to change the inner tube due to a snake bite, fortunately I did not have to change the tube on my bike ride, only when I came home the tyre felt significantly weak, it only had 4 bars/58 psi left inside, and later on the tyre went flat in the basement. For on my way, I use butyl inner tubes (Continental light, around 70gr - I always have two, to feel better when I used one), as they are easier to handle when you have to change the inner tube when the tyre is wet or even dirty.
Great to hear your insight! Why did you switch from Vittoria to Vredestein? And what do you mean with "glued rim tape and non of plastic"? Isn't rim tape always from from plastic? Thank you!
@@frodo5882 I switched to the Vredesteins as they are far lighter (Vittoria 85gr, Vredestein 55gr). As rim tape, I always use Velox, except on the DT Swiss carbon wheels, there I left on the tubeless rim tape. There are also plastic rim tapes available which have no glue (e.g. the lightblue hp rim tape from Schwalbe, or the yellow one from Michelin), there it can happen that the edges fold up and cut the latex tube, especially where the nipple holes are, which may lead to an exploding latex tube - this happened once to me about 20 years ago. On carbon wheels you have to take care not to overheat the rim in case you still use rim brakes, release the brake lever at the latest when the brake pads start to squeak. Usually both the wheel manufacturers and the inner tube manufacturers explicit exclude the use of latex inner tubes respectively the use of carbon wheels with their products. On my Shamal HPW and a Cosmic Carbon SSC front wheel, I closed the nipple holes with Veloplugs, and put a Vélox rim tape over it, to be sure there won't appear any problems. When you decide to use vredestein latex, be sure to tighten the valves well, I usually use a small amount Pattex repair glue on the valves thread to be sure the valves are sealed, but they still loose 2 bars in 24 hours. Especially when you plan longer rides, keep that in mind.
@@overcookit1433 Because of the heat problem with Latex on rim brakes, I was planning to try TPU tubes this season. They seem to be more heat resistant than Latex. Did you try them at all? I live in the mountains, so heat resistance is quite important and so far I stuck with the normal butyl tubes. As rim tape the Schwalbe Tubeless looks promising too. It's also glued on. You may want to try it.
Currently using Cyclami 38g TPU, I'm so impressed with its weight/ air retention & road performance. Every time I ride w/ TPU just like ride w/upgraded wheels set. But got punctured/ leakage due to quality issue on some manufacturer is so frustrating anyway.
I switched to TPU tubes several months ago and really like the gains with one exception. I have not been able to get a patch to hold on a puncture. I have cleaned carefully with IPA even tried different patches but nothing has worked successfully. A GCN Tech video would be very helpful.
I always use Michelin Aircomp butyl ultralite tubes. 75g . very light weight and no threads on the valve. With no threads, the rubber chuck gasket on my Silca Track pump lasts for 10 years. With a tube with valve threads, you have to replace the chuck gasket every year or two.
A great thing I discovered about TPU is that you can fix them super easily with a soldering iron and a bit of spare tpu inner tube because you can melt them together
Switched from 21/butyl to 28/tpu and the new setup is insanely more comfortable and faster. Even tried them so low pressure that the rim was hitting sharp edges (old durable wheels, don't care), with that little experience they seem to hold just fine. Of course I will pump them up a bit (just enough, around 60-70 psi). TPU gets you most of a tubeless setup without the maintenance.
Have used butyl the most. Tried latex and loved the feel. But as mentioned, did not like having to maintain pressure constantly. I found this also made them more susceptible to pinch flats. Started using Ridenow TPUs. In the last 2 years, I've had one really annoying valve with a slow leak. Since then, no issues. Love the Ridenow TPUs for the balance of price, performance, and practicality
You forgot to add one fact about TPU tubes - they can be risky for rim-brake bikes, especially on a downhill from mentioned Stelvio pass ;) then can be melted by the heat of the rim from braking.
First, I'm curious to know which of the three is best for the environment. Being a consumable, I would like to use the most environmentally friendly product. Second, pertaining to latex tubes and air leakage, I've been riding bikes for a very long time and I can't imagine ever leaving for a ride without checking my tire pressure. Maybe it's just me but that's not even an option. Great video!
I thought the same about checking pressure for years until I realized that the real issue is the pressure drop you get in your tires throughout a long ride/race. You end up having to spend a third of the ride overinflated, a third about right and you finish underinflated. Adding air pre-ride has always been a red herring in terms of not using latex though..
I just got back from a 5400 km road ride from Cyprus back to the UK, using Schwalbe Aerothan TPU tubes with Conti GP 4-seasons tyres. I was a little apprehensive about the choice, so took 5 spare tubes! Fortunately I only had to use two of them, although with the first puncture being on only the third day of the trip I was worried for a while. The last 2 years i have also used Pirelli and Tubolito TPU tubes. I have had problems with leaks at the valve stem/tpu interface, and once at the tpu/tpu junction. Repairing punctures has not been straightforward, but with Aerothan i have found Schwalbe's own repair kits good, although not easy to procure. After a first repair failed, i tried using flexible superglue as a hole filler before applying a new patch, and that has held ok.
I’ve used butyl tubes my whole life until switching to tubeless (on a gravel bike) this year. I want to get some TPU tubes as flat backups for their size (not weight).
I have been riding TPU for over 1.5 years already, as Alex said, I feel the puncture resistance quite similar to traditional tubes, and even though they are more expensive, every time I puncture I always fix them, I currently have around 10 patches on each inner tube I was badly replacing traditional inner tubes almost every single time I flattened, so at the end of the day it's not "that expensive". Great video btw.
I have, but didn´t like it and went back to TPU, probably it was just bad luck and 1 bad experience, I´´ll give tubless another chance in the future@@gcntech
Not mentioned for butyl is thickness and the use of talc or other dry lubricant. It used to be standard practice decades ago to dust inner-tubes with talc to prevent them from sticking to the tyre.
I’m sticking with butyl only because I had an ungodly frustrating search trying to find inner tubes for my 650b 28mm tires. Specialized had my exact size, and they work beautifully, so I’m sticking with them. LoL.
I run with latex on all my bikes, 7 bikes, both summer and winter. On average I cover 16,000km in a year and I’ve had little or no punctures. That said, the winter bike has 4 season tyres fitted. I love the feel of latex on the road and checking pressures every morning is not that much of a chore. With regard to a spare tube, I have a TPU with a 60mm valve. It packs small and is nice and light.
Ive got schwalbe aerothan tpu tubes in my pinarello, pirelli in my basso which all perform as one would expect. I bought several ride now tpu tubes and two failed athe valve on day one. Ive got cyclami in my winter bike which i find are the best compromise. The are a few grams heavier , 35 grams total, because they have metal valves. Where the valve meets the tube is very well reinforced and a pump grips valve like a butyl tube. Ive patched several tpu tubes with no problems as long as the instructions are followed. However i strongly recommended the tubilito repair kit. I bought a cheap one of aliexpress along with tubes and when the patch is placed on glue it completely rolls up as if affected by glue and it is very difficult to effect a good repair. The last two cyclami tubes i bought came with a self adhesive patch which i take with me along with spare tubes. Several of my ridding buddies have switched to tpu on my recommendation and are suitably impressed with them.
Just changed to TPU and so far think they are great. I woud recommend doing a trial fitting in the comfort of your own home as there is a correct and easy way of fitting TPU tubes
it's nice to finally have a video covering the 3 types (tube types and rolling resistance is always coming up in videos, but never in this level of detail)! could you say something about patchability? can they all be repaired/patched?
I'm running latex in my kids' bikes for road and cross. Mostly did it to save weight for them. When I install the tubes I put in 2oz of latex tubeless sealant and give a 1oz top up at 3 months. I've noticed that with more modern setups, kids are running 26c tires on 20mm internal rims at 65-70psi the tires only need a top up every 2 days, usually down to 58-60psi on day two. After a couple months of the sealant being in there they can go 3 days before they drop below about 58psi and need to be topped up. When swapping to the cross tires a month ago I could also see that one of the tubes must have gotten a puncture as there was a little bit of orange liquid on the tube but the tire never stopped holding air which makes them the best of both worlds for me; light and puncture resistant.
Hi @gcntech, Would be cool to include additional criteria to any review like this: Sustainability Impact - in terms of their production and when it comes time to bin/recycle such items.
320tpi tires with latex tubes was by far the most comfy and fastest ride I've ridden. Currently on tubeless for the self-sealing ability on punctures though.
Ive been using unbranded TPU tubes (from ebay) £3.88 at the time and they have been fantastic! Hoping the brand names ones come down in cost as there is no reason other then profit for the huge markup on them atm
Switched from butyl to pirelli TPU tubes. The bike feels more alive for lack of better word. It just feels better, can't really explain but I can definitely forgive the cost of the tubes for the better ride quality.
Good video. I'd have liked if you'd covered the reparability of each tube as that definitely affects the price. I've never had anything but butyl, but I could be tempted to other types if they're easily repaired.
This. I'm a big fan of TPU except that in my experience they don't repair well at all, even when using the manufacturer's special (expensive) patches and following the instructions religiously. Repairability is almost never mentioned in reviews...but it's essential.
@@JoelBlack-kh5up yeah, I like having patches in case I get more than one puncture on a single ride, as a last resort. They say TPU is compact, but I’d like to know that it’s worth carrying a spare if it can also be patched.
@@JoelBlack-kh5up I've had great success with Park Tool Super patches GP-2. Currently running a TPU with two patches. Been on the bike for six months so far, no issues.
just switched to tpu and conti gp5000's from butyl and Bontrager R2's difference is night and day considerably faster . I bought the Green CYCLAMI Chinese tpu tubes off ali express they ended up only costing around 7 euro per tube. i did have a pinch flat but that was my fault could have avoided the pot hole
I've been tubeless for 3 years on the road, always carried butyl tubes in case of catastrophic failure. Fortunately it's never happened, but I just switched to TPU for backup. Can easily carry 2 in the space of one butyl. Now I've never installed or ridden them, but for carrying around, they're tops.
Good comparison, but did not hear any comments on repairability. This is related to value vs butyl which, of course, can be easily repaired. I normally use butyl, but switched to latex for recent Ironman as they seemed faster and lighter - x4 with the 2 spares (and smaller). Also nice to be able to upgrade some components like tyres and tubes on race day. How easy are TPU and latex to repair?
Alex - However count : 1. 1:20 2. 4:24 3. 4:43 4. 4:55 5. 5:45 6. 6:08 It felt like more - maybe because of that accumulation between 4:24 & 6:08. That is 6:14. GCN - can you loop Howerver and similar thing into 1 episode ?
I have used everything from $3-$25 a piece inner tubes in my time doing BMX and I can say no matter how expensive you will end up casing a quarter inch gash in them no matter what if you really ride your bike so just use whatever your budget affords. Although If you get a lot of flats I recommend Slim's tubes with the sealant already in it. They are extremely heavy but they will survive multiple small nail punctures.
I haven't put any on the bike yet but I have 2 TPU tubes in my saddle bag in case I have a puncture. I have had 2 tubes on the bike for many, many years and twice I've used both and once I had 3 punctures on a ride with the final a few hundred metres from home. If you're carrying a spare/s then TPU is the obvious choice.
I've tried using light tubes and latex tubes before, they always flatted on me. I now only use heavy standard rubber tubes. First time I used latex tubes, they both flatted on me at the same time.
In 2021 I switched to latex inner tube combined with Specialized cotton 28 hell of the north edition knock on wood super fast and comfortable and most important no punctures
I wanted to love TPU, but I kept getting slow leaks from where the valve connects. I assume just a bad batch or something, but makes them hard to love. I carry one on my tubeless setup because it’s so small, but stick with butyl for my winter commuter.
Agree. I had TPU tubes and the air leak is twice as fast as butyl. The weak point is the plastic stem. After a year the plastic thread has worn out and cannot hold the metal valve tightly. Now I carry TPU as a spare only.
I have used Latex tubes for years and love them. Had 1 puncture in the last 3 years so don’t believe what people say about them being fragile that’s an urban myth. You do have to install them with care to avoid damaging them with tyre levers or pinching them under the tyre bead. I also dust the inside of the tyre and rim with talc. Just this year for the first time i’ve started testing TPU tubes. Initial results are good and I’m considering making the switch as I’ve started riding audax events and TPU tubes hold pressure better over 12-24 hours.
That experience matches mine. 3 flats in 5 years vs around 12 for the previous 5 with butyl. Initial installation requires a little more care with latex though, specially new tyres that haven’t stretched. I’ve used butyl for spares to not worry on the road and allow for easy patching in the case of multiple punctures.
@@billeterkIn the rush of changing a tube , during those RTF events of amateur races, using a TPU is the worst thing I would do to myself. Very light butyl for me as spares and latex for the road.
I am using Vittoria's butyl inner tubes with sealant inside for my commute bike - I have 28mm wide Vittoria Zaffiro Eco (allrounder) tyre. They are not lightweight and definitely they have quite high rollong resistance. But for commuting it is a good set. I think I will try tpu inner tubes in a following year.
I switched from butyl to latex tubes this year and noticed an increase in my average speed. Also I haven’t had a single puncture in thousands of miles. I don’t use the bike everyday so I don’t mind having to pump them up every time I go out. I wouldn’t want to keep a latex one in my saddle bag though as they are fiddly to fit compared to butyl ones
I recently changed over to TPU tubes, and I was shocked at the weight reduction, rolling resistance and increased comfort. As Alex said, "it's a thing."
Guys. Thank you for this video comparison for the Tubes, but I'm disappointed that you didn't mention repairing any of them, once. It's not all about RR, weight and price. An opportunity missed on this one!
Another advantage of latex is that in case of a major puncture, they tend to lose air more progressively and not go flat instantly like butyl does. Gives you to time to stop safely.
I recently switched to FOSS TPU tubes for 4€ each. They are quite heavy, but you get all the other advantages including a very cheap price, which makes them the best for me as enthusiastic commuter. They are not the best performer and you cannot repair them so easily but for this price I can except a few downsides.
Been running latex with gp5000 for a long time and have been loving the comfort from the first moment. I tend to run the tubes very low pressure though, bike+rider is around 85k for me and I’m sitting at 72 psi front and 77 psi back, lower than most calculators out there recommend for 25c
Swapped bikes the other day and forgot to pump up the rarely used bike. Same combo - GP5000 + latex. Turns out they’re rideable for an 85kg rider at 45PSI :-)
Just tried a TPU tube on my rear wheel of my daily bike last week. The most pronounced thing is that my tyre felt more supple. They do hold air better than latex but still noticeably worse than butyl. I was always inflating to 110 psi once a week and it would fall to about 80 before inflating again. Tried to do the same thing now and the TPU had 40 psi.
Latex in coton clinchers for great sensations on no rain days, latex cutout patches and tiny glue tube roadside repair kit, tiny CO2 inflator and a spare ultralight TPU and tyre boot patch in the jersey pocket in case of disastrous puncture.
Made the switch to TPUs at the start of the year and have completed 5 audaxes of various distances and a failed PBP attempt. No punctures so far and a noticeable improvement in ride comfort.
I’m using TPU tubes and like the feeling, but it is really sad when I have to throw one out (sad because they’re so expensive). However, I’ve found that they can be reliably patched with Park Tools glueless patches. I’m using tire liners as well which significantly reduces the number of punctures I get. Another thing that I don’t think you mentioned is that TPU tubes are temperature sensitive. They can’t be left in direct sunlight when inflated or the glue can fail and that can’t be fixed. And if you have a puncture and are trying to locate it by putting the tube under water, warm water can ruin the tube as well.
Honestly I had no idea that TPU tubes are temp sensitive. That's a big no for me. I was considering it. But I live in Oregon, where we often expect temps north of 100°f and that would surely melt it. That would be like a whole dang oven. Latex will be my bet then.
@@diehardbikes it does only seem to be an issue if the tire is left in direct sunlight and pressurized. It happened to me when I left my bike out in the sun to dry after a wash. So I learned from that one time and now I just let a bunch of air out of the tube before I leave the bike in the sun like that.
@@diehardbikes I have a very hard time believing a hot day, let alone warm water, will damage a TPU tube. According to the American Chemical Society, TPU will begin to soften and degrade at temperatures at or above 93C, which is well above the temperature at which humans will die. This temperature threshold is definitely a concern if you're using TPU tubes with alloy wheels and rim brakes, which can get very hot indeed, or if you're planning a gravel ride on Venus, but otherwise heat tolerance is probably not a legitimate concern. In addition, TPU apparently has a lifespan of about 10-20 years, which is similar to butyl and a lot more than latex. It's not a very fragile material.
I live in Taiwan and I recently found an unbranded TPU tube for US $ 4...28 grams! And...of course...I had to try. 😂 So far I rode 150 km and they're just fine. No problem at all. Of course I can't predict how long they last...Will see. But, so far so good.
I’ve been carrying TPU tubes for a long time as a tubeless spare. Luckily I’ve ever had to try one so I have no experience with them other than they take almost no space in my saddle bag.
The problem I've had with inner tubes is finding them with long enough valves for deep section wheels - i need 80mm valves. I've not yet found a suitable latex inner tube or be able to add valve extensions. And not found any fatter tubes for 32mm tyres with 80mm valves.
Tpu is King 👑, can carry two spare tpu tubes for a fraction of the weight and space Vs one butyl. Can still be patched and if you know the sites. Just as cheap as them too.
Been riding Ridenow TPU for a while, but switched to tubeless when I punctured front and rear at the same time in a 15% decent. Front had 16! snake bites rear had 4 snakebites. Switch to a new TPU, after few days rear tire 2 snake bits. Before this I drove them 3 months without problems. Maybe it's the combination of rimbrakes and warmer weather. Tire pressure was the same whole time. Tyre is new GP5000 #askgcntech
Interesting! I’ve been running RideNow TPU tubes previously without problems but have recently had 5 punctures -all snakebites! To be fair, one double puncture wasn’t surprising as I managed to hit a pretty nasty rock with both wheels.
Yes, 16 snake bites in the same tube at the same time. In a 15% decent. A few minutes earlier I hit a hole, maybe it started leaking slowly which caused the other snake bites.
I recently tried some latex tubes - which were noticeably lighter than the butyl tubes I'd been using BUT the latex tubes were more sensitive to handle and noisier than the butyl tubes. Also having to inflate them before each ride - even re consecutive days, was a pain. I've now changed back to butyl tubes for autumn/winter riding and will give the latex tubes another go next spring.
I just can’t bring myself to go tubeless so TPU is my choice. I like that they pack smaller than latex and they’re more robust so I’m not so worried about ruining one just trying to get it mounted.
Also don't know what butyl tubes they are buying but I was running butyl tubes that came in at 72 grams for a 25mm tire, half the weight quoted by GCN.
There are other issues not mentioned in the video: compatibility of some tube types with rim brake bikes and tpu tubes reliability, specifically the valves when using valve extenders with deep rim wheels
Currently running RideNow 36g TPU's (the 2nd gen with the transparent valve stems) they cost about 4 pounds each, compact & easy to carry spares & definitely can feel less rolling resistance when riding. Air retention is decent i suppose, losing about approx 5 psi+- a day. There's even a 19 gram disc only variant. (36g is compatible with rim brakes but they do caution against prolonged braking)

Which inner tubes do you use? 🚴 Let us know in the comments below! 👇
TPU and Latex sound better when rolling across tarmac, but in my experience you get far more road buzz than standard butyl tubes with these options.
I think one of the more standout differences between the tubes is what happens when you puncture. In my experience TPU deflate almost immediately, latex loses air quickly and screams like you’re releasing air from a balloon (can be quite daunting), where as butyl punctures and releases air slowly giving you time to limp to a safe stop. So put yourself in the scenario, you’re descending on a lovely set of carbon rims and puncture around 50kmph+, having those extra seconds before you start grinding away your fancy carbon hoops could be the difference between a near miss, scratch, cracked rim or even a potentially nasty crash. So on that premise I think Butyl should still be the choice of the people, but TPU and Latex certainly have their place given the conditions 👌🏻
Butyl so not pump up often but no matter what one only tyre bead could cause puncture
Just curious as said about tpu and butyl what is difference on air retention
TPU is the best!!
@@sogamdok I use TPU and carry 2 spares. Weight = 100g. 4 x butyl weigh = 560g that's a saving of 460g or 1lb. That's brilliant bang for your buck imho.
10 and half minutes of video and you guys left key information out. 🙄 Latex tubes cannot be used on a rim brake bike with carbon clincher wheels. They're not very heat resistant and can fail in a carbon wheel as they do not dissipate heat as readily as alloy wheels. TPU can only be patched with manufacturer specific patches, if at all. Some brand TPU tubes have also had issues with leaks coming from the valve stem where the valve is plastic welded into the valve stem. Ask me how I know. TPU tubes also stretch when inflate for the first time. Subsequently, you can use the same tube to change from a 25mm tire to a 28mm tire, but once the tube is "stretched" to size, you may have issues if you step back down because it does not shrink like a Butyl or Latex tube.
Wow,those were key points.. thanks bro👍
That is right. I really struggle to fit tpu to 32c tires after using them in 35c. But it can be done of course
this is what I came here for
Complete info… thanks
@@christophertrapp4195 for aluminium wheels 25c you will go with tpu od latex?
I've been on latex on 2 road bikes for over one year and can deffo feel the difference, and lower rolling is a fact. Have to check tire pressure every ride, but I did that before anyhow, not an issue for me. They are diffidently Smoother and quieter. Have a tpu as a spare, they are brilliant for that, light and small.
Sounds like the ideal setup! TPU are certainly the nicer option to carry as a spare!
Exact same set-up and it was immediately noticeable when I switched from butyl to latex. Have to be a bit more careful when initially fitting them, which is another reason why TPU are better to carry as a spare.
you think that you wont have to check tire pressure with tubeless? You probably wont even have pressure!
Ive been on 1 bike with tubeless for 3 years and 2 sets of tires. Never had a flat.
Not sure I understand why inner tubes makes a difference to rolling resistance? I mean, they are never in contact with the road? 🙃
Only Alex and Ollie could have that much fun discussing... inner tubes.
We already knew they were massive nerds 😉
Solid info here, you nailed this one. I'm a latex tube guy myself. Pumping them daily is no big deal because it's so important to ensure tire pressure is correct, I always did that daily even with butyl tubes.
As a racer, I've used all three types of inner tube. And tubeless.
For me, tubeless doesn't seal above 50psi. I've been stranded too many times. Much easier to get going with an inner tube setup. Latex is fast but fragile. TPU can be found cheap online and makes a cool sound when rolling. If including the spare, you'll save about 300g in weight. I'm not going back to butyl.
I run tubeless at 80-85 PSI, and have no problems. I don't race, but I do high mileage and have some fast, twisty descents in my area, so I feel like I've tested them in pretty demanding conditions.
I did have an issue when I first switched my road bike to tubeless, but found that you need to be more careful with the rim tape on a road bike than you do on an MTB, presumably because of the higher pressure.
Started with butyl, then for a short time TPU, and now the last 4 years I ride Vredestein Superlight Latex inner tubes with Michelin Power 25mm tyres, this is for me the best and fastest combination.
+1 vote for vredestein superlites.
Why? Isn't the tpu lower rolling resistance?
Michelin tyres are awesome
@@comedyman112 The latex tubes make for a smoother, less 'bouncy' and therefore faster ride. That is: in my case. All bikes, wheels and tyres and roads are different, so are the results.
@@comedyman112 tpu is lower weight, latex is lower rolling resistance. latex also still weighs less than butyl
Just switched to tpu, more compliant ride. Had a normal flat, used the pirelli puncture kit: worked great.
Switched to (Pirelli) TPU over summer, from butyl, and can definitely feel a more lively but compliment ride. Like it. No punctures yet. Cost soon forgotten. What's strangely weird is NOT smelling rubber when you let the air out.
I also switched to the Pirelli TPU this summer and you can definitely feel the reduction in rotational weight when accelerating and climbing. I’ve been riding the Pirelli cinturato velo tires with the TPU tubes and haven’t had any problems with punctures.
Sold. Not having to deal with Fish Friday is worth it’s weight in gold.
That’s what she said
Just get some patches for when you get a flat. Super cheap and work great! Even if you just use the patched ones for training or as your spares.
Traditional tubes are trivial to repair in field and a patch kit - of 50 patches and two glue tubes - will last several years. I had tubes with as many as 15 patches applied to them before I had to trash the tube. Likewise - butyl tubes play nicely with tubeless sealant ( yes, i know ), which creates double-protection against punctures - which Is great for commuting.
They completely glossed over the issue of potential new hassles with puncture repairs. Perhaps they think our sponsors will always be there at the side of the road with free replacements whenever we get a puncture?
@@redalert2834It is super easy to patch TPU tubes and they are so tiny, you can always take spares with you.
If anything, TPU is better at the road side puncture repair.
To be fair, I am not confident about a 16 patch tpu tube, but I never had more than 2 patches on a butyl either, because they start to feel clunky with those patches.
I definitely patched tubes like crazy before. I couldn't fathom going back after switching to tubeless though. I live in the land of goatheads. 3-4 flats a week(sometimes not even getting off my street😵💫😅) down to maybe plugging 3 tires a year.
*sealant sucks in tubes. It's simply better than nothing
@@3dprintersawhiteboard401 What types of patches do you use? From what I have heard, TPU tubes are nearly impossible to permanently patch (even with the manufacture supplied patches).
@@veganpotterthevegan Years ago I lived in goat head country. I had heavy duty tubes, Kevlar liners and tires with a lot of Kevlar. Yes - I used Slime too. After I did that the flats stopped.
I have been happy with the RideNow TPU tubes. (GP5000 tires & Alpinist CLII wheels.) A lot of the roads around here are pretty rough and they've held up fine.
Only problem I have with them is the shipping time.
@@Mavczers to my house are only 9 days from aliexpress
I ordered 6 tpu tubes last year and they all puncture within 2022. It was rough.
With little hope I order the new 26grams tpu tubes from Ride Now and changed my tires from gp5000 to conti Grand Prix GT.
With great pleasure I can say have been puncture free for all 2023 with this combination.
RideNow all the way
@@Mavczers I ordered 4 and they came in 9 days, I was honestly surprised on how quickly they showed up as I was expecting at least a month wait! Looking forward to running them
Ollie is building quite a trusted persona. He's a smart guy. He's passionate about technical details. He's eager to learn about product performance. He's intellectually honest. Ergo... we can trust what he says.
In Ollie we trust 🙌 He's well and truly earned his nerd status 🤓
I’ve been using Latex (Vredestein) for 15 years now on my road bikes. I wouldn’t use anything else! Much better feel and I think my secret weapon to going fast on the flat or downhill. I carry butyl as a spare and use butyl in my commuting/ shopping bike. Would only ever consider TPU for hill climb races which I probably will never do as I’m useless uphill! Incidentally I use Vredestein fortezza tricomp (old stock), now superseded by fortezza senso. The higher TPI version not the cheaper all weather. I have not had a single puncture in 15 years due to anything getting through the tyre. The only punctures I have had are when the latex tubes age (after about 5 years) and fail typical around the valve stem or abrasion on anything sharp on the inside of the wheel such as caps covering the spoke holes which I was using instead of rim tape to save weight. Just thought I’d mention as Vredestein rarely gets a mention. Grip is also excellent (better imho than equivalent conti GP) though arguably they wear out faster. They certainly feel fast especially with latex tubes.
I just swapped to TPU ridenow tubes. Very very suprised and the weight saving is great. I just put up a review up on my channel of my first experience with them. 👌👍
Hey, I wanted to ask you, is there any noticeable handling difference between butyl and TPU? Or which ones feel more comfortable on the road, thanks.
@@xmarcika the only difference I noticed to start with was accelerating from a stop. But after a while it becomes a normal feeling.
switched from butyl to tpu and love it. the price is higher but if you compare it to other bike tech this is probably by far the best upgrade per $. today i found out i have been riding over 500km with a thorn in my tire and tube.
No better feeling than when you find an upgrade the fits your riding style 🙌 Did you pull the thorn out or leave it in?
@@gcntechi i was in a train and had time to change to a new tpu tube. guess i could have finished the planed 100km ride without any problem.
I use lightweight butyl tubes on some of my bikes. But I use tpu in the saddle bag, can fit 3 tubes in a smaller space, and carry a small tpu repair kit, just in case.
Sounds ideal! Smaller spares are a good idea!
Recently switched to Schwable Aerothan 60mm on GP5000s with Roval Rapide CLX rim brake wheels. It’s important to mention that TPU can be used on Carbon Rim Brake wheels. I rode a 100 miler with TPU and had no issues. There were some rough roads and had no issues. I believe they inner tubes helped my climbs and speed on the flats.
I've gone tubeless on all my bikes now. However I always carry a spare tube just in case. TPU is perfect for this, the small size is biggest advantage. When I have used them they have been faultless and I haven't really noticed a difference from the tubeless set up. Well worth the additional cost and probably the best bang for buck upgrade you can make on your bike, even if it's just carrying it around unused.
Been riding Ride-Now TPU for over a year. Love not having to inflate every day, tiny, light, and has no need for talc, unlike Latex. Slowly converting all my bikes to TPU over Buytl and Latex. If it wasn't for ride-now, then it would only be the best bikes.
Excellent video and commentary on this topic. TPU for everyday high-performance use (and who doesn't like that) and latex on race/event day. Butyl for touring, commuting, budget, and ease of patching. They have a very long useful life.
Love this video! Very informative and helpful, I was wondering if there was something wrong with my latex tube because it was deflating overnight , now I know!
Thanks for an interesting video! It would have been nice to have a segment on if and how the tubes can be repaired in case of a puncture.
The very expensive latex ones are the hardest to repair by far. It's throw them away most of the time. A shame they omitted that. Bad for our wallets!
Latex tubes (green or pink), 28mm GP5000 on wide HED Ardennes rims at 38-40 psi: comfort, speed and easy to maintain. Cornering with wide rims is something you have to experience to appreciate, the 28mm and HED rims make this possible (no light bulb deformation of the tire in cornering). Great job guys, as usual. Need to come up with a new "doctor" moniker for Ollie...
I have been using the Continental Supersonic butyl inner tubes (around 50gr. with 42mm valve) since they were launched, but three years ago I switched to latex - first the Vittorias, and then to Vredestein latex (ivory coloured, and 52 grams with 50mm valve, here in Germany you can get tem already for 8,50 Euro), I also use them on my deep section carbon front wheels (62mm and 80mm DT Swiss). Although I had used the lightest butyl inner tubes available, the use of the latex was a revelation, especially on descents. The Vredesteins loose 2 bar/29psi per day (in case you pump the tyres up early, and want to use the bike the whole day, take this in account), but they are worth it. I inflate the tyres before each ride anyway (I also did so with the Supersonic inner tubes), it does not matter (and my rides last 2.5 to 3 hours max.). I even inflate all bikes regularly during winter, to prevent the tyres getting flat. It is essentially to use talkum, and to use only glued rim tape and none of plastic - it can happen that the sharp edge of those rim tapes (e.g. the light blue one of Schwalbe or the yellow of Michelin) cut the latex tubes, and be sure to refasten the valves, as most tyre companies don't attach them to strong, so it is easier to put them out in case you have to use valve extenders. As I recently had to change the inner tube of my front tyre, I saw that the drillings for the spoke nipples have quite remarkable sharp edges, at least DT Swiss should grind them away before putting on the tubeless tape (or put on two layers of rim tape, in case this is cheaper). I had to change the inner tube due to a snake bite, fortunately I did not have to change the tube on my bike ride, only when I came home the tyre felt significantly weak, it only had 4 bars/58 psi left inside, and later on the tyre went flat in the basement. For on my way, I use butyl inner tubes (Continental light, around 70gr - I always have two, to feel better when I used one), as they are easier to handle when you have to change the inner tube when the tyre is wet or even dirty.
Great to hear your insight! Why did you switch from Vittoria to Vredestein? And what do you mean with "glued rim tape and non of plastic"? Isn't rim tape always from from plastic? Thank you!
@@frodo5882 I switched to the Vredesteins as they are far lighter (Vittoria 85gr, Vredestein 55gr). As rim tape, I always use Velox, except on the DT Swiss carbon wheels, there I left on the tubeless rim tape. There are also plastic rim tapes available which have no glue (e.g. the lightblue hp rim tape from Schwalbe, or the yellow one from Michelin), there it can happen that the edges fold up and cut the latex tube, especially where the nipple holes are, which may lead to an exploding latex tube - this happened once to me about 20 years ago. On carbon wheels you have to take care not to overheat the rim in case you still use rim brakes, release the brake lever at the latest when the brake pads start to squeak. Usually both the wheel manufacturers and the inner tube manufacturers explicit exclude the use of latex inner tubes respectively the use of carbon wheels with their products. On my Shamal HPW and a Cosmic Carbon SSC front wheel, I closed the nipple holes with Veloplugs, and put a Vélox rim tape over it, to be sure there won't appear any problems. When you decide to use vredestein latex, be sure to tighten the valves well, I usually use a small amount Pattex repair glue on the valves thread to be sure the valves are sealed, but they still loose 2 bars in 24 hours. Especially when you plan longer rides, keep that in mind.
@@overcookit1433 Because of the heat problem with Latex on rim brakes, I was planning to try TPU tubes this season. They seem to be more heat resistant than Latex. Did you try them at all? I live in the mountains, so heat resistance is quite important and so far I stuck with the normal butyl tubes.
As rim tape the Schwalbe Tubeless looks promising too. It's also glued on. You may want to try it.
Love Ollie just casually wearing the aero base layer :D
Currently using Cyclami 38g TPU, I'm so impressed with its weight/ air retention & road performance. Every time I ride w/ TPU just like ride w/upgraded wheels set. But got punctured/ leakage due to quality issue on some manufacturer is so frustrating anyway.
I switched to TPU tubes several months ago and really like the gains with one exception. I have not been able to get a patch to hold on a puncture. I have cleaned carefully with IPA even tried different patches but nothing has worked successfully. A GCN Tech video would be very helpful.
I also switched to tpu and have read they are not meant to be patched once punctured they should be replaced.
@@tfire28 Nonsense. I've repaired my TPU tubes with the patches provided and the Park Tool patches with no issues at all.
I've had great success with Park Tools Super patches GP-2 - they work!
The Ali express TPU tires are 8 dollars and they are amazing
I always use Michelin Aircomp butyl ultralite tubes. 75g . very light weight and no threads on the valve. With no threads, the rubber chuck gasket on my Silca Track pump lasts for 10 years. With a tube with valve threads, you have to replace the chuck gasket every year or two.
A great thing I discovered about TPU is that you can fix them super easily with a soldering iron and a bit of spare tpu inner tube because you can melt them together
I'm a convert to TPU for some years, yes the most expensive but completely worth it. There's even patch kits for them. Not going back to butyl.
Switched from 21/butyl to 28/tpu and the new setup is insanely more comfortable and faster. Even tried them so low pressure that the rim was hitting sharp edges (old durable wheels, don't care), with that little experience they seem to hold just fine. Of course I will pump them up a bit (just enough, around 60-70 psi).
TPU gets you most of a tubeless setup without the maintenance.
I love Ollie's commitment to the aero cause, rocking the aero bra just to make a video about inner tubes.
Have used butyl the most. Tried latex and loved the feel. But as mentioned, did not like having to maintain pressure constantly. I found this also made them more susceptible to pinch flats. Started using Ridenow TPUs. In the last 2 years, I've had one really annoying valve with a slow leak. Since then, no issues. Love the Ridenow TPUs for the balance of price, performance, and practicality
You forgot to add one fact about TPU tubes - they can be risky for rim-brake bikes, especially on a downhill from mentioned Stelvio pass ;) then can be melted by the heat of the rim from braking.
Isn't that more of a problem with latex? And also more of a problem with carbon wheels with rim brakes, not alloy wheels?
I think you meant Latex tubes with carbon clinchers...
First, I'm curious to know which of the three is best for the environment. Being a consumable, I would like to use the most environmentally friendly product. Second, pertaining to latex tubes and air leakage, I've been riding bikes for a very long time and I can't imagine ever leaving for a ride without checking my tire pressure. Maybe it's just me but that's not even an option. Great video!
Butyl for the win in 2023. ❤
I thought the same about checking pressure for years until I realized that the real issue is the pressure drop you get in your tires throughout a long ride/race. You end up having to spend a third of the ride overinflated, a third about right and you finish underinflated.
Adding air pre-ride has always been a red herring in terms of not using latex though..
I have had the same latex tubes in constant use since 2017.
@@rachaelmurray8051 Wait. Not just the same brand but the same actual tubes? That's amazing! Good for you. Which ones are you using?
I got mine from Silca. Yes same tubes! @@CatManDoSocial
I just got back from a 5400 km road ride from Cyprus back to the UK, using Schwalbe Aerothan TPU tubes with Conti GP 4-seasons tyres. I was a little apprehensive about the choice, so took 5 spare tubes! Fortunately I only had to use two of them, although with the first puncture being on only the third day of the trip I was worried for a while.
The last 2 years i have also used Pirelli and Tubolito TPU tubes. I have had problems with leaks at the valve stem/tpu interface, and once at the tpu/tpu junction. Repairing punctures has not been straightforward, but with Aerothan i have found Schwalbe's own repair kits good, although not easy to procure. After a first repair failed, i tried using flexible superglue as a hole filler before applying a new patch, and that has held ok.
The editing and the camera usage was top notch 👌🏾
Best Biking channel out by far! love these guys!!!
I’ve used butyl tubes my whole life until switching to tubeless (on a gravel bike) this year. I want to get some TPU tubes as flat backups for their size (not weight).
I put tpu tubes on mine and i love them. No issues so far what so ever. World of improvement to the butyl.
I have been riding TPU for over 1.5 years already, as Alex said, I feel the puncture resistance quite similar to traditional tubes, and even though they are more expensive, every time I puncture I always fix them, I currently have around 10 patches on each inner tube I was badly replacing traditional inner tubes almost every single time I flattened, so at the end of the day it's not "that expensive". Great video btw.
10 patches wow! It's great that you are looking to repair your parts 🙌 Do you think you would ever jump to tubeless and avoid tubes all together?
Interesting! Do you have any issues with the plastic valves (and thus valves breaking / becoming unusable / leaking after some months / a year?)
I have, but didn´t like it and went back to TPU, probably it was just bad luck and 1 bad experience, I´´ll give tubless another chance in the future@@gcntech
only once with 1 tube, put some white tape under the valve and it got fixed and never leaked again, I use tubolito@@l.d.t.6327
Not mentioned for butyl is thickness and the use of talc or other dry lubricant. It used to be standard practice decades ago to dust inner-tubes with talc to prevent them from sticking to the tyre.
I’m sticking with butyl only because I had an ungodly frustrating search trying to find inner tubes for my 650b 28mm tires. Specialized had my exact size, and they work beautifully, so I’m sticking with them. LoL.
Having riding tubs for years, I've been slowly converting to pretty pink Vittoria latex, on my climbing and touring bikes. KB
How have they been working for you?
Great indecisive conclusion
I run with latex on all my bikes, 7 bikes, both summer and winter. On average I cover 16,000km in a year and I’ve had little or no punctures. That said, the winter bike has 4 season tyres fitted. I love the feel of latex on the road and checking pressures every morning is not that much of a chore. With regard to a spare tube, I have a TPU with a 60mm valve. It packs small and is nice and light.
Ive got schwalbe aerothan tpu tubes in my pinarello, pirelli in my basso which all perform as one would expect. I bought several ride now tpu tubes and two failed athe valve on day one. Ive got cyclami in my winter bike which i find are the best compromise. The are a few grams heavier , 35 grams total, because they have metal valves. Where the valve meets the tube is very well reinforced and a pump grips valve like a butyl tube. Ive patched several tpu tubes with no problems as long as the instructions are followed. However i strongly recommended the tubilito repair kit. I bought a cheap one of aliexpress along with tubes and when the patch is placed on glue it completely rolls up as if affected by glue and it is very difficult to effect a good repair. The last two cyclami tubes i bought came with a self adhesive patch which i take with me along with spare tubes. Several of my ridding buddies have switched to tpu on my recommendation and are suitably impressed with them.
Just changed to TPU and so far think they are great. I woud recommend doing a trial fitting in the comfort of your own home as there is a correct and easy way of fitting TPU tubes
it's nice to finally have a video covering the 3 types (tube types and rolling resistance is always coming up in videos, but never in this level of detail)!
could you say something about patchability? can they all be repaired/patched?
I find that latex tubes patch as easily as butyl. Haven't tried TPU yet.
TPU patch easily with Park Tools GP-2 super patches
Right after watching this I went out for a ride and got a pinch flat (Butyl tyre). I'm gonna go buy a couple of TPUs to try.
I'm running latex in my kids' bikes for road and cross. Mostly did it to save weight for them. When I install the tubes I put in 2oz of latex tubeless sealant and give a 1oz top up at 3 months. I've noticed that with more modern setups, kids are running 26c tires on 20mm internal rims at 65-70psi the tires only need a top up every 2 days, usually down to 58-60psi on day two. After a couple months of the sealant being in there they can go 3 days before they drop below about 58psi and need to be topped up. When swapping to the cross tires a month ago I could also see that one of the tubes must have gotten a puncture as there was a little bit of orange liquid on the tube but the tire never stopped holding air which makes them the best of both worlds for me; light and puncture resistant.
Hi @gcntech, Would be cool to include additional criteria to any review like this: Sustainability Impact - in terms of their production and when it comes time to bin/recycle such items.
Love that Canyon Aeroad. A superb bike!
320tpi tires with latex tubes was by far the most comfy and fastest ride I've ridden. Currently on tubeless for the self-sealing ability on punctures though.
Ive been using unbranded TPU tubes (from ebay) £3.88 at the time and they have been fantastic! Hoping the brand names ones come down in cost as there is no reason other then profit for the huge markup on them atm
I had to throw my cheap ebay TPUs in the bin after one month, both were leaking from the valve joint.
There IS a difference. Pirelli has higher QC standards for their TPU, whereas generic QC is whatever was good enough at that unknown factory.
... no other reason than* profit
Switched from butyl to pirelli TPU tubes. The bike feels more alive for lack of better word. It just feels better, can't really explain but I can definitely forgive the cost of the tubes for the better ride quality.
Good video. I'd have liked if you'd covered the reparability of each tube as that definitely affects the price. I've never had anything but butyl, but I could be tempted to other types if they're easily repaired.
This. I'm a big fan of TPU except that in my experience they don't repair well at all, even when using the manufacturer's special (expensive) patches and following the instructions religiously. Repairability is almost never mentioned in reviews...but it's essential.
@@JoelBlack-kh5up yeah, I like having patches in case I get more than one puncture on a single ride, as a last resort. They say TPU is compact, but I’d like to know that it’s worth carrying a spare if it can also be patched.
@@JoelBlack-kh5up I've had great success with Park Tool Super patches GP-2. Currently running a TPU with two patches. Been on the bike for six months so far, no issues.
just switched to tpu and conti gp5000's from butyl and Bontrager R2's difference is night and day considerably faster . I bought the Green CYCLAMI Chinese tpu tubes off ali express they ended up only costing around 7 euro per tube. i did have a pinch flat but that was my fault could have avoided the pot hole
I've been tubeless for 3 years on the road, always carried butyl tubes in case of catastrophic failure. Fortunately it's never happened, but I just switched to TPU for backup. Can easily carry 2 in the space of one butyl. Now I've never installed or ridden them, but for carrying around, they're tops.
Install them on your next sealant change, not as comfy as tubeless, but my tubolito's have been just as resilient as tubeless
@marquesreyes3287 Thanks! Worth a try.
Good comparison, but did not hear any comments on repairability. This is related to value vs butyl which, of course, can be easily repaired. I normally use butyl, but switched to latex for recent Ironman as they seemed faster and lighter - x4 with the 2 spares (and smaller). Also nice to be able to upgrade some components like tyres and tubes on race day. How easy are TPU and latex to repair?
Alex - However count :
1. 1:20
2. 4:24
3. 4:43
4. 4:55
5. 5:45
6. 6:08
It felt like more - maybe because of that accumulation between 4:24 & 6:08. That is 6:14.
GCN - can you loop Howerver and similar thing into 1 episode ?
Didn't notice at first, but then it does trigger every time you hear that British "houea" 😅
I have used everything from $3-$25 a piece inner tubes in my time doing BMX and I can say no matter how expensive you will end up casing a quarter inch gash in them no matter what if you really ride your bike so just use whatever your budget affords. Although If you get a lot of flats I recommend Slim's tubes with the sealant already in it. They are extremely heavy but they will survive multiple small nail punctures.
I haven't put any on the bike yet but I have 2 TPU tubes in my saddle bag in case I have a puncture. I have had 2 tubes on the bike for many, many years and twice I've used both and once I had 3 punctures on a ride with the final a few hundred metres from home. If you're carrying a spare/s then TPU is the obvious choice.
For me, it comes down to which tube is easiest to patch on a ride and I find the old Butyl to fit the ease-to-patch category best.
With tpu you twist another tpu and then fix it at home.
pretty obvious that all the climax created would end into something like "it depends..." Kudos to Alex for at least nailing his opinion
I've tried using light tubes and latex tubes before, they always flatted on me. I now only use heavy standard rubber tubes. First time I used latex tubes, they both flatted on me at the same time.
In 2021 I switched to latex inner tube combined with Specialized cotton 28 hell of the north edition knock on wood super fast and comfortable and most important no punctures
I wanted to love TPU, but I kept getting slow leaks from where the valve connects. I assume just a bad batch or something, but makes them hard to love. I carry one on my tubeless setup because it’s so small, but stick with butyl for my winter commuter.
Agree. I had TPU tubes and the air leak is twice as fast as butyl. The weak point is the plastic stem. After a year the plastic thread has worn out and cannot hold the metal valve tightly. Now I carry TPU as a spare only.
I have used Latex tubes for years and love them. Had 1 puncture in the last 3 years so don’t believe what people say about them being fragile that’s an urban myth. You do have to install them with care to avoid damaging them with tyre levers or pinching them under the tyre bead. I also dust the inside of the tyre and rim with talc. Just this year for the first time i’ve started testing TPU tubes. Initial results are good and I’m considering making the switch as I’ve started riding audax events and TPU tubes hold pressure better over 12-24 hours.
That experience matches mine. 3 flats in 5 years vs around 12 for the previous 5 with butyl. Initial installation requires a little more care with latex though, specially new tyres that haven’t stretched. I’ve used butyl for spares to not worry on the road and allow for easy patching in the case of multiple punctures.
@@billeterkIn the rush of changing a tube , during those RTF events of amateur races, using a TPU is the worst thing I would do to myself. Very light butyl for me as spares and latex for the road.
I am using Vittoria's butyl inner tubes with sealant inside for my commute bike - I have 28mm wide Vittoria Zaffiro Eco (allrounder) tyre. They are not lightweight and definitely they have quite high rollong resistance. But for commuting it is a good set. I think I will try tpu inner tubes in a following year.
I switched from butyl to latex tubes this year and noticed an increase in my average speed. Also I haven’t had a single puncture in thousands of miles. I don’t use the bike everyday so I don’t mind having to pump them up every time I go out. I wouldn’t want to keep a latex one in my saddle bag though as they are fiddly to fit compared to butyl ones
I would buy anything from these two guys, they capture the entire essence of the golden age of infomercials
I recently changed over to TPU tubes, and I was shocked at the weight reduction, rolling resistance and increased comfort. As Alex said, "it's a thing."
Guys. Thank you for this video comparison for the Tubes, but I'm disappointed that you didn't mention repairing any of them, once. It's not all about RR, weight and price. An opportunity missed on this one!
It's GCN, what do you expect?
Another advantage of latex is that in case of a major puncture, they tend to lose air more progressively and not go flat instantly like butyl does. Gives you to time to stop safely.
Switched to latex on my road bike in 2017 and have never looked back. Light, comfortable, fast.
Tubeless got me stranded so MANY Times! I hate hookless rims and tubeless tires! I am forever into tubes!
I recently switched to FOSS TPU tubes for 4€ each.
They are quite heavy, but you get all the other advantages including a very cheap price, which makes them the best for me as enthusiastic commuter.
They are not the best performer and you cannot repair them so easily but for this price I can except a few downsides.
Been running latex with gp5000 for a long time and have been loving the comfort from the first moment. I tend to run the tubes very low pressure though, bike+rider is around 85k for me and I’m sitting at 72 psi front and 77 psi back, lower than most calculators out there recommend for 25c
Swapped bikes the other day and forgot to pump up the rarely used bike. Same combo - GP5000 + latex. Turns out they’re rideable for an 85kg rider at 45PSI :-)
This is also exactly what I run and I love it.
Me too. Great Combo
Same combo here, too. 🙋♂️ Love it. Though I did pick up a pair of cheaper TPU tubes to carry as spares.
Sounds like you've done your research!
Just tried a TPU tube on my rear wheel of my daily bike last week. The most pronounced thing is that my tyre felt more supple. They do hold air better than latex but still noticeably worse than butyl. I was always inflating to 110 psi once a week and it would fall to about 80 before inflating again. Tried to do the same thing now and the TPU had 40 psi.
Alex, how are you liking the Aeroad? I've had mine 3 months now, same color, Force, and LOVING it!! Is that YOUR bike?
Latex in coton clinchers for great sensations on no rain days,
latex cutout patches and tiny glue tube roadside repair kit, tiny CO2 inflator and a spare ultralight TPU and tyre boot patch in the jersey pocket in case of disastrous puncture.
What a nice duo
Made the switch to TPUs at the start of the year and have completed 5 audaxes of various distances and a failed PBP attempt. No punctures so far and a noticeable improvement in ride comfort.
I’m using TPU tubes and like the feeling, but it is really sad when I have to throw one out (sad because they’re so expensive). However, I’ve found that they can be reliably patched with Park Tools glueless patches. I’m using tire liners as well which significantly reduces the number of punctures I get. Another thing that I don’t think you mentioned is that TPU tubes are temperature sensitive. They can’t be left in direct sunlight when inflated or the glue can fail and that can’t be fixed. And if you have a puncture and are trying to locate it by putting the tube under water, warm water can ruin the tube as well.
Honestly I had no idea that TPU tubes are temp sensitive. That's a big no for me. I was considering it. But I live in Oregon, where we often expect temps north of 100°f and that would surely melt it. That would be like a whole dang oven. Latex will be my bet then.
@@diehardbikes it does only seem to be an issue if the tire is left in direct sunlight and pressurized. It happened to me when I left my bike out in the sun to dry after a wash. So I learned from that one time and now I just let a bunch of air out of the tube before I leave the bike in the sun like that.
@@diehardbikes I have a very hard time believing a hot day, let alone warm water, will damage a TPU tube. According to the American Chemical Society, TPU will begin to soften and degrade at temperatures at or above 93C, which is well above the temperature at which humans will die. This temperature threshold is definitely a concern if you're using TPU tubes with alloy wheels and rim brakes, which can get very hot indeed, or if you're planning a gravel ride on Venus, but otherwise heat tolerance is probably not a legitimate concern. In addition, TPU apparently has a lifespan of about 10-20 years, which is similar to butyl and a lot more than latex. It's not a very fragile material.
I live in Taiwan and I recently found an unbranded TPU tube for US $ 4...28 grams! And...of course...I had to try. 😂 So far I rode 150 km and they're just fine. No problem at all. Of course I can't predict how long they last...Will see. But, so far so good.
I’ve been carrying TPU tubes for a long time as a tubeless spare.
Luckily I’ve ever had to try one so I have no experience with them other than they take almost no space in my saddle bag.
The problem I've had with inner tubes is finding them with long enough valves for deep section wheels - i need 80mm valves. I've not yet found a suitable latex inner tube or be able to add valve extensions. And not found any fatter tubes for 32mm tyres with 80mm valves.
Tpu is King 👑, can carry two spare tpu tubes for a fraction of the weight and space Vs one butyl. Can still be patched and if you know the sites. Just as cheap as them too.
This came at an opportune time as I've had 2 tubes burst just sitting indoors and a number burst with gentle rides and during install.
Been riding Ridenow TPU for a while, but switched to tubeless when I punctured front and rear at the same time in a 15% decent. Front had 16! snake bites rear had 4 snakebites. Switch to a new TPU, after few days rear tire 2 snake bits. Before this I drove them 3 months without problems. Maybe it's the combination of rimbrakes and warmer weather. Tire pressure was the same whole time. Tyre is new GP5000 #askgcntech
Interesting! I’ve been running RideNow TPU tubes previously without problems but have recently had 5 punctures -all snakebites! To be fair, one double puncture wasn’t surprising as I managed to hit a pretty nasty rock with both wheels.
You got 16 snakebites in the same tube at the same time? I'm curious.
Yes, 16 snake bites in the same tube at the same time. In a 15% decent. A few minutes earlier I hit a hole, maybe it started leaking slowly which caused the other snake bites.
I recently tried some latex tubes - which were noticeably lighter than the butyl tubes I'd been using BUT the latex tubes were more sensitive to handle and noisier than the butyl tubes. Also having to inflate them before each ride - even re consecutive days, was a pain. I've now changed back to butyl tubes for autumn/winter riding and will give the latex tubes another go next spring.
You forgot to talk about patching a punctured inner tube. Butyl and latex uses the same patches, but TPU needs a special patch and glue
I just can’t bring myself to go tubeless so TPU is my choice. I like that they pack smaller than latex and they’re more robust so I’m not so worried about ruining one just trying to get it mounted.
Also don't know what butyl tubes they are buying but I was running butyl tubes that came in at 72 grams for a 25mm tire, half the weight quoted by GCN.
There are other issues not mentioned in the video: compatibility of some tube types with rim brake bikes and tpu tubes reliability, specifically the valves when using valve extenders with deep rim wheels
Currently running RideNow 36g TPU's (the 2nd gen with the transparent valve stems) they cost about 4 pounds each, compact & easy to carry spares & definitely can feel less rolling resistance when riding. Air retention is decent i suppose, losing about approx 5 psi+- a day. There's even a 19 gram disc only variant. (36g is compatible with rim brakes but they do caution against prolonged braking)
How long is prolonged braking?
Recently ordered a pair of TPU tubes on Ali for 6.6$. If they work fine, it will be the best ever profit)
Very nice to know that Ollie likes latex. Even Super Nice!
