Hello,
According to you, what is the most reliable brand (and link on Aliexpress) :
- Ridenow
- Cyclami
- Geoid
- Other
-
Good question.
I would also add Thinkrider to that list, as they often sell very cheap in the "3 for 4.99$" section.
However, my personal experience is limited to the old Ridenow 36g (black valve stem) and they were flawless. With the 19g Ridenow (transparent valve stem), I had one flat, but that would have been a flat with any tube.
-
Indeed, I forgot Think Rider. Ridenow seems to have a 26g with aluminium valve.
What is the max pressure inflate for those TPU ?
-
From monitoring the weightweenies thread with tons of experience it seems cyclami is rated a bit lower due to more frequent leaks and bad valve cores. I've barely ridden my ridenow in disc wheels but I just put the $2.50 thinkrider tubes this season on my rim brake bike and so far so good, even after potholes where I might have punctured with butyl. And I live in a very hilly area, 150km/3600m last week
-
Offbondage for me. Had 4 sets of ThinkRider and all failed at the valve stem/tube interface. When you compare the Offbondage to ThinkRider at the point of failure, the Offbondage is manufactured much superior and that involves multiple layers or boundaries of ultrasonic welding to assure airtight fit. They had a sale and were 8.5 Eur for a pair.

It is not specified, but I run 7bar (100 psi) on 24mm SWorks turbo tyres and have no issues. I'm 6 months with using them and still going strong.

Anyone tried the Magene TPU tubes? https://www.magene.com/en/exar/65-exar-tube-700c-ultralight-tpu-inner-tube.html

This guy, and I think GPLama had them too. Price seems a bit outrageous for what it is

ridenow - never failed me boutght 8 Tpus road and gravel
buy thinkrider buy twice they are absolute junk
-
Just bought 3 Ride Now TPU tubes from Ali
2 for the bike with 1 spare.
1 had a leaky valve out of the box. Luckily Aliexpress was able to refund me quickly and i'll just have to order one or 2 more.
-
Ride now- great on roadbikes
not so great on Gravel- very prone to pinch flats(snake bites).
running them at35-40psi on maxxis ramblers 40mm i am 90kg .
3 of 4 tubes failed on each ride.
update
reached out to Info@ridenow and explained my reservations about buying ridenow again and Eric responded and some over and back i asked could he send a repair kit(tpu cement etc- the good one) as a gesture.
he sent two and 6 gravel tubes.
cant fault that kind of service
-
I prefer Offbondage since they come with alloy stems and valve covers. Plastic stems can crack and leak. Though ThinkRider tpu tubes can be bought for cheap. I usually buy mine through AliEx Pick 3 & Save.
Since my local urban roads suck, I tend to run lower PSI pressures, about 5-10 psi lower than optimal. I've been able to minimize punctures this way with tpu tubes. If I were racing on smooth tarmac, I'd run higher pressures. If I were running wider tires like 30-32c, I'd probably go tubeless. Though I like to climb and prefer the nimbleness + lower weight of 25c road slicks. Also on 21mm internal width rims, my 25c tires widen out close to 28c so I get the advantages of both a narrow tire (less weight) and wide tire (more contact patch).

For me RideNow has been very reliable.
With the thinkrider tubes, I had some quality issues with.

I can attest to the minor lack of nimbleness when running 30/32c for road. I'm currently testing a set of wheels that stretch 30c GP5000s to 33mm at the rim. The amount of road comfort is absolutely optimal. Basically game changing. But even if it 33mm isn't actually any slower, my heart too still prefers the nimbleness of 28c on a 21mm internal rim.
I'm a full Ride Now TPU convert. My primary bike has wheels with 28mm ext 21mm int. With 28c GP5000s I'm running around 76psi front and 78psi rear. Pinch flats and punctures are basically non existent. I probably get a true puncture maybe once a year at most. But for gravel...yeah tubeless for sure.
-
I’ve been running the 19g RideNow tubes. I’d say 1 in 6 have a slow-leak valve defect, and the risk of pinching when installing/swapping is like 1 in 4 for me—and I think with 15 years of racing and tube-swapping experience, I’ve gotten better over time but they really require far more care and patience during install compared to butyl or latex.
I think they’re price competitive with tubeless (as in they don’t eat away the price savings of buying the clincher version over tubeless of the same tire), lighter than tubeless, same RR as latex, same air retention as butyl. So I just buy a 4 or 6 pack and assume 1 is going in the trash.
-
I have used RideNow with mixed success, early versions I used were leaking - newer versions I bought seem okay.
Typical Chinerproblems: products are being changed constantly & randomly, it is virtually impossible to understand what version you are using and if improved versions are available or not...
I have ordered ThinkRider but not tested, so far, and I have a pair of Cyclami that I am using without problems
-
i ride the Ride now tubes on all my road bikes. Zero trouble don't know why anyone would use tubalitos
-
With Ride now I got 2 flats a month apart, one pinch and one puncture. I was completely shocked since that is more flats than I get from butyl tubes, have not had a flat in 4 months since the last one.
-
No one mentioned another brand called Spingo. Those are thicker than any other TPU tubed and much more puncture resistant. As a result they are also heavier around 45 grams for 80mm valve. The RideNow are 36g.
This is the only TPU brand that I had no flats, yet. Every other brand including RideNow, Cyclami, OffBondage, ThinkRider I had flats or slow leaks or got destroyed during installation because they were too thin. The Cyclami and ThinkRider had poor quality valve base and leaked air from where the valve was attached. It also be noted once they have a puncture its better you throw them out as the repair kit patches don't hold well onto the material and eventually start leaking air.
Also if you are on gravel these will go flat. Good for road use only. For gravel I am tubeless for life.

I might explore wider road tires again if I ever get 23-25mm internal width carbon road wheels. My gravel wheels are 25mm internal width w/38c tires and the power transfer and road feel are excellent. I've been tempted to try some road slicks on them to see how they handle.
-
With Ride now I got 2 flats a month apart, one pinch and one puncture. I was completely shocked since that is more flats than I get from butyl tubes, have not had a flat in 4 months since the last one.
1 flat for me in 2 years. my tyre had a gash in it no tube would of lasted the gash. Sorry about ur bad experience.
-
Using ride now tubes now for one and a half years on two bikes and no trouble. Just a snakebite as I hit a deep pothole in a groupride.
So I would recommend it.
The last batch I ordered was equipped with transparent valves. Does anyone know why they switched to transparent and if the black valves are available yet?
-
Using Ridenow ever since they first came out. The first few batches were very inconsistent. The latest ones with the transparent valves are the most reliable for me. I’m talking about the 36g version. I found these to be pretty much as reliable as butyl tubes.
I can also recommend the repair patches from Cyclami. Those work very well. I’m currently riding with one patch on the front tube and two patches on the rear. And they keep holding air. I’d even be confident enough to patch a TPU tube on the side of the road if necessary. Though it can be quite hard to actually find the puncture.

Have you tried their last model with aluminium valve ?

No, I have not. Are these the latest iteration? I noticed they released „allroad“ tubes at around 45g for tires up to 34mm or bigger I think? But those still have plastic valve stems.

I believe it but I am not sure. There is also Geoid brand.
-
I use Ridenow myself still have to check tire pressure before rides as they do lose a little. I also treat them as single use I find the repair patches at cr@p and don't adhere to well.
-
I use ridenow and love them. Cyclami patches works good for me. With new tubes (clear white valve) I also got pair of pink ridenow patches and used them on one of the tubes with success.
-
Do your inflated inner tubes extend far enough where the two parts are sealed together? I have one that doesn't widen enough at this point. The inflated tire therefore shrinks on the sides at this location.
-
Yes, I had one Ridenow inner tube with exactly this problem. Not sure anything can be done about this? I ended up ditching it.

I don't think so. I tried to keep inflate at high pressure my tire but It did not do anything.
I don't know if It happens often.
-
Yesterday the Thinkrider tube I had in my back wheel just exploded and tore off a stretch of the tire clincher. Looks like the failure started near the valve, the tube probably was around the 1000 km range.
Luckily I was on flat road and not going fast so I could stop with no problems.
Will be trying RideNow or some other brands here recommended now.

It's scary. What pressure was the tire inflated to?
-
It's scary. What pressure was the tire inflated to?
It was around 6-6.2 bar in a 28 mm tire
-
I'm running a ThinkRider tube on one of my bikes, but I'm only at 70 psi on 28c tires. I find these TPU tubes don't need to be inflated as highly as butyl or latex. maybe 5-10 psi under.
-
It was around 6-6.2 bar in a 28 mm tire
that's a lot. i run 4,9/5,1 on 28mm Schwalbe one which measure 30mm on the rim and i'm 110kg in system weight.
-
I'm using RideNow 42g on my Gravel and Offbondage on my road.
I still add some air before every ride, might be micro leakage, like mentioned by some :-\
No issues besides that.

Ridenow with plastic or metal valve ?
-
I had gotten some purple OFFBONDAGE tpu tubes earlier in the year as my first experiment with tpu. I had a particularly difficult tire to mount and was really dismayed when I finally got it mounted and the tube was leaking at the valve. I had bought from Amazon so I returned them all and just decided to go tubeless.
Local LBS convinced me to try again for another bike I have with 23c tires. The mechanic there is really chill and was not interested in selling me anything. I asked him if he knew of any better brands he had tried and he just shrugged and said he had good luck with various cheapo brands from Amazon. I just installed some of the RideNow 36g tubes with the plastic valves and they seem fine. Installed well, no leaks, and just rode about 50 miles on them so far.
-

I will try to ride at a lower pressure, thanks. I'm kind of a cycling newbie and my Decathlon tire sidewall says "minimum 6 bar" so I complied ;D
-
3 ridenow tubes and 2 thinkrider tubes here... No leaks, hold air very well (esp the thinkrider, as good as butyl), and have definitely sustained conditions that would have gotten me punctures on butyl before. Very happy with both
-
Have you seen a real improvement of rolling resistance compared to a butyl inner tube ?
-

Huge and very noticeable difference. Same tires ride very differently with butyl and TPU tubes. Will never go back to butyl tubes.
-
Do you know which one of the Offbondage is the last model ? (Yellow valve or black/metallic valve)
I hesitate between Offbondage or Ridenow like everybody I think :D.

The black/metallic valve came in at a later date and they advertise it as upgraded weight even though it is heavier. If you mind gold, go with black. That is the main difference between them. Have not tried Ride now, but a friend had them with plastic/transparent valves and they both leaked at the valve, so basically the same experience as I had with Thinkrider, only more expensive. On the other hand, I have 5000km on a single set of Offbondage TPU tubes, and not to jinx myself, no issues so far. Just a regular top up with air on every other ride.
-
using cyclami here... so far runs almost 2k with ultrasport tire in my old bike... still riding fine...
-
I have used a few RideNow tubes of the older kind with black plastic valve stem and they were hassle-free until they weren't. Valves fine, valve stems fine, just the tubes themselves might eventually develop micro holes that you can't really fix (too small to find and they usually come by the dozen).
I am still riding them and I would probably buy more.
-
I've only gone to using TPU recently and I've had some flats that forced me to change tubes a few times. It was all entirely road damage and not the tube's fault in every case. I'm now on my 3rd or 4th RideNow tube and every one has been great. I'm only going to be buying RideNow from now on, considering the issues I had with leaking valves on some other TPU brands I tried a while back. I've now used both the RideNOW 36g tubes and the RideNOW 24g tubes and each worked fine. I realized a little too late that I should probably try repairing my tubes rather than just throwing them away, so I'll probably try that for future flats.
-
I recently bought a pair of Meroca TPU tubes just because it was enough to trigger the coupon deal I was trying to get from the same store. Surprisingly they've been holding air quite well with slightly less daily air loss.

Afaik, TPU is TPU (Thermoplastic polyurethane). I pick my TPU tubes based on whatever's cheaper on AliX. I have a friend who says he's got a slow leak on his. I've punctured 3 & broken at least one. A friend broke 2 trying to fix one puncture.
I presume that if you spend 35 eur on a tubolito, you wont have slow leaks, even though they can't test them because once you've inflated a TPU tube, you can't fold it nearly.
But if you get them for c.4 eur, then if sometimes you get a dud, put a new one. I've setup probably 12 to 15 wheels w these tubes, and more often than not, whatever TPU goes in works just fine.
Critical though: be careful during installation. They are easy to twist / pinch / break (at the valve).
TPU is TPU, but how the seams are made, how the valve is reinforced at the seam, and what the valve joint is made of seems to vary quite a bit between all the brands. It's worthwhile to spend time discussing which brands are fabricating them better at scale.
-
I dont disagree per se, but we can also spend time what a "brand" means in a chinese context, especially via aliexpress. There's zero guarantee / assurance that what's called TPU from brand X at T0 will be the same item / quality / spec next time you order.
I thought that was the entire point of this site, right? That might be true for some brands, and less true for others. By each sharing our experience with the brands, something valuable may be learned. I was pointed towards the RideNow tubes by hearing such stories, and I get the impression they are just a slight cut above some of the others based on my own experience.
-
I am trying out a new brand called OVTK for both my gravel and road, i think its sold on aliexpress but im getting them from taobao. they made a video on why TPU shouldn't be so thin and most TPU brands do not control the circumference of the tube. The bonding of the valve to the tube plays a huge part as well.
after trying out the 19g Ridenow and having them not last more than 2 rides, i am convinced to run slightly thicker TPU tubes

-
Yeah. I prefer the 36g Ridenow tubes for this reason. They’re still durable enough to quickly change them on the side of the road without fear of damaging them. And they’re light and supple enough for me. And you can still take three of those with you for the weight of one butyl tube. The 18g versions are pushing it too much I fear.
-
The 18g ones are impossible to patch up too. The thicker, heavier ones are better in that the patches adhere well and don't leak air. My experience anyway. I have thrown away a bunch of 18-24g tubes after one tiniest of leaks.
-
I also use 36h RideNow version and they are doing good. As for patching the RideNow patches are absolute trash, therefore I buy cyclami patches and they hold really well. Heard good things about park tool patches also.
-
Had my first blow out of a TPU tube today. The bang was scary! Luckily this was after pumping up the tire at home, and wasn't on a crazy descent. Been using RideNow for over a year on a rim brake bike and never had a blow out before.. Definitely noticed though the balloon effect on used TPU tubes so the heat of rim brake does affect the integrity.

Looks like RideNow have a version with a pink (alloy?) stem with a black base (I assume it's some kind of material covering the stem to help with durability). Has anyone tried these? Are they newer then the white stem version?

I have those. The pink section is alloy indeed and in contrast to some other TPU tubes these have removable valve core too. Additionally these also have a tightening ring that plastic stem TPUs don't have. Even the cap is metal and color matched. These weigh 40 grams so slightly heftier but I like these better.

Yes, they are the new version. I have these and they seem to be higher quality than the valve on the white version.
And the pink valve is very cute 8)
-
I've noticed those "new" RideNows with the allow stems, but avoided them because why mess with success? My limited experience with tpu tubes was that if the tube was going to have an issue it would be an issue with the valve or the bonding around the valve. But, if you guys say it seems improved, then I guess my next lot will be of the "new" style.
I guess RideNow seems to have their act together a little more than some of the others, I've noticed. If they say it's an improvement, I guess you gotta trust them.
-
my favorite tpu tube is the Cyclami. You get a lot of tubes for $4usd.

Are they better now? I bought the 1st gen Cyclami tubes with non replaceable valve core and they all started leaking air slowly for no apparent reason. I couldn’t find where. So I avoided them ever since. Their repair patches are great though.
-
I can compare with traditional butyl tubes, tpu (Cyclami included) tends to hold air longer than the butyl tubes.

if its plastic stem, check at valvecore;
other brands using plastic stem may suffer this too, including ridenow, if your pump head is the clip-secure type n you yank off the head pulling a bit the core once you done pumping

i just ordered ofbondage 85v to try.
so far i have tried:
- revoloop ultra 60v
- ridenow 1st gen 36g 45v
- ridenow 2nd gen 24g 45v, 65v, 85v
- thinkrider 85v
thinkrider 85v lenght is measurement from base to core tip, but ridenow measures the valvestem itself excluding the core tip.
using on my 86mm rear rim, i dont need to use extender when using ridenow 85v
*i can bareley get away not using extender on thinkrider 85v, but i need to hold my pump head as its borederline gripping the core
-
Tested Ridenow last year alot of flats went back to butyl to be sure. :s
If the new version is better maybe I should try them :)
-
Had ordered ofbondage 85v with gold valve, as my first tpu tube.
It started it leak due to bad interface with the valve :(. Had used it for less than 200Ks.
Has anyone successfully repaired a tube with leaky valve? ( the seam at the valve insert isn't done well thus bottom of valve leaks air in high pressure or upon bending the valve )
Worst case, I know have a sacrificial tube for puncture repairs.
Currently on offbondage regular black/silver values, hoping these last better.

My experience with all sorts of different iterations of these TPU tubes from Cyclami, Ridenow and now also Offbondage is: If the valve is leaking, there seems to be little you can do about it. I certainly haven't been able to stop it. Punctures however can be repaired reliably with most of them with good patches, like the Cyclami ones. In fact I'm currently riding a Ridenow tube with 2 patches on it that works just fine. But if the valve stem is giving me trouble, I usually dump them. But I only really had leaky valves with the first gen of Ridenow and Cyclami tubes.
-
The inner tubes on the market today are too thin. We bought some stock inner tubes that were 19mm thicker than the competition but weighed only 45 grams. From an initial pressure of 100 psi, the air leakage was about 2 to 3 psi per day, while the competition leaked 5 to 10 psi per day.

using Cyclami 26g 60mm metal-presta valve here...
positive experience with it... tire is ultrasport25c and runs more than 4600kms never replace and lucky without any puncture... i just need to pump once a week to 6bar and i can ride for 3-4consecutive days...
my other set with tire of kenda28c max 80psi and same need to pump once a week...
negative experience... all from my kenda28c set
got 1leak on the valve as i tighten much the nut...
got 1blown up due to the weak rim tape
got 1puncture and put a patch but not used until now, just my reserve...
still my go to tube brand since it has metal valve which i think it will last longer than the plastic valves...
-
I use Ride Now. I bought a case of them because I like to have spares.
I have tried ThinkRider, my success was spotty. Two flats.
-
Just a quick note, I learned the hard way that Topeak fly paper glueless patches work really well on TPU tubes. It's been 4 days since I punctured and did a roadside repair with them. Holding very well without losing air more than what is usual for TPU tubes. Just scuff up the puncture site gently to make adhesion better and that's it.
-
I use RideNow, 36 gram version, great value for the price. I've done around 7k on a pair, only puncturing once due to my tire being sliced open. Other than that, they are rock solid. They do loose pressure a bit quick than I would like, but I pump my tires before almost every ride anyway, so not a big deal. ;D
-
I've been using aliexpress tpu tubes for a few years now, recently swapped them all over to the Ridenow 36g which do feel thicker and sturdier when you get them out of the packaging. I've not had any problems with them yet.
Another cheap and cheerful option are the orange thinkrider tubes you can find them in the buy 3 bundles section of aliexpress.

Are new ridenows (metal valve) more robust around valve to tube area and core to valve area?
Also I have heaps of punctured ride now's from gravel, anyone know best way to fix them?
I had them paired up with maxxis ramblers and got pinch flats every ride.
Moved to Vittoria mixed and light butyls and no issue since.
Might try Vittoria with RNs.
Original RNs were very weak where valve meets tube and seating on rim etc ,great for road(TT etc) .

I repaired 2 TPU with this :
https://a.aliexpress.com/_EHN1G1W
I rode 1000 km without any problems. Don't wait the glue to be dry before installing the patch (as opposed to butyl repair kit).

I find TPU to be very sensitive to things like the tires and rim tape. 3 out of my 4 bikes have no problems. On the 4th- GoZone carbon spoke wheels, GP5K TT, Ridenow 24gs- I kept getting flats on the rear only. I prob went through like 5 tubes. Finally I replaced the rim tape and went back to a regular GP5K on the back. So far no problems
Im heavier (89kg at the moment) so Im wondering if I'm overweight for the GP5K TT.... front has been fine.... but switching everything out seemed to solve the issue. If your wheels have spoke holes on the rims its def worth getting some thick high quality rim tape at the minimum. Also dont bother with cotton rim tape, makes tires impossible to mount.

The new Ride Now TPUs with alloy valves and removable core has been a game changer for me.
I have a set of Yoeleo C88 Pro wheels, and finding long enough valves was a struggle. Now I can just add the included Yoeleo valve extenders and problem solved. 85mm valve length + extenders.
The new packaging now crams two tubes into a single package which is nice to cut down on waste. It also includes more patch repair kits and multiple options to prevent the valves from rattling inside the rim. Super thoughtful stuff.
Overall I went 2 years without a single puncture on RN TPUs. But this past season I had probably 4. This was prior to the new design, but the punctures had nothing to do with the tubes themselves. Just bad luck on the road.
Last summer I got a puncture during our weekly "race" pace ride. Imagine going 35mph/56kph approaching a sprint segment getting swarmed by 40 other riders...and hearing what sounded like a gunshot. Thankfully I kept it upright. But that was the end of my ride. I hit a road lane reflector which obliterated my rear tire.
-
Hi Patrick,
Yes that's the thing about you tubes and flats,it's relatively immediate,not gradual like butyl,a tad dangerous at speed.
-
The new RideNow TPU tubes seems to be significantly better than previous generation. I've installed a set for a four days, 250 km into them and I didn't need to add air to proper pressure yet.
Another aspect I'm quite unhappy with about TPU tubes is that they don't react very well to total deflate and re-inflate. When I change tires (switching from road to CX tires and back) after two or three such switches they start to develop pores or something, and over the night they loose 2/3 of the pressure. And obviously, they don't resist to a single session of riding. I'm not pinching them at the installation, they just seem not to like this scenario.
Let's see how the newer ones fare with this scenario.
-
This is a documented drawback from TPU: they don’t reset to their initial state. Hence, changing tyres width is probably a no-go (at least going from wider to narrower tyre.

Wow, that's illuminating... now it makes sense.
That's such a pity... I want to change tire frequently, on an all-road bike, from 38mm light gravel tires to 30front-32rear road tires. That's why I'm not going tubeless.
But I guess I have to make pairs of tires+tubes and check if it works.
Thanks again.

My friend, you need another wheelset. I couldn't imagine changing tires that frequently based on terrain I want to ride. In fact, on my gravel bike, I keep a separate wheelset when I want to ride it on-road, but even with that I am so lazy I seldom feel like changing even the wheel. Thankfully my gravel tires are pretty smooth rolling on road so for most shorter rides I just leave it all alone.
-
You're so wrong, my friend!!!!
I need another bike!
In fact, several ;D :D ;)
On a serious note... it's not quite that frequently.
Sometimes it would be twice a weekend, sometimes I might stay a whole month with the same tire.
I'm an old weekend warrior, anyway! 8)

I got some of the 19g Ridenow tubes for a weight weenie build and they seemed to go flat just by looking at them wrong. Would definitely recommend going with heavier ones! I did get some 36g ones but my wheels are all tubeless rn so they're just backup. I haven't actually needed one yet.
-
I've been using a pair of RideNow 24g TPU tubes with clear plastic valve stems in a pair of 28c tyres. They've been great, they hold air really well. Note that they're only designed for max 28c tyres.
On another bike I use the RideNow all-road tubes with clear plastic valve stems - the 39g ones for 28c-38c tyres. Same great experience with these.
Previously I used the Offbondage 40g tubes with black&silver coloured valve stems, again no issues.
The only TPU tubes I've had issues with are:
- Older RideNow tubes with black plastic valve stems.
- Older Cyclami tubes with threaded metal valve stems.
-
I ordered geoid inner tubes. They say they are stronger than butyl, maybe they did some tests

ridenow older gravel tubes are useless
paired with maxxis rambler tyres and adequate pressure for my 90kg frame
puncture every ride- must have 6/7 tubes in shed waiting to be repaired.
road they are fine!

Geoid are nice but some of them don't expanse enough around the juncture. It makes a shrink tire for 2 cm.

For me RideNow has been very reliable.
With the thinkrider tubes, I had some quality issues with.
Question for you and others here. Are y’all buying the Ridenow TPU off Aliexpress? I see prices from .99 to 30.00 each. Anyone with link if you are using Aliexpress.
Thanks. I thought carbon wheels were overwhelming but nothing compares to TPU.

Just look around, you cannot go wrong, usually I go for the least expensive one. Keep in mind there are two different versions available, one with the metal removable valve and one with the plastic one. I believe Patty said the metal valved ones are a newer version. They are also a tad bit more pricey.

I usually go with Ridenow—puncture resistance mainly comes down to the tyres rather than the tubes. Has anyone tried the metal-valved Ridenow tubes?
-
I have to make pairs of tires+tubes and check if it works.
This should work fine till you can get extra wheels or another bike(s). I remember a long time ago I used one mountain bike for everything – racing and trail riding on weekends, and commuting on weekdays. I'd swap between a couple of different 2"+ knobby tires to 1.25 Fat Boy slicks. Made a pretty good difference to make it worthwhile. But yeah match the tubes to the tire and just swap both at the same time.
-
Thanks for the replies. Any others are still welcome.
-
I finally just went full tubeless and stopped using TPU tubes. I'm using Panaracer Agilest slicks and they're the lightest tubeless road slicks I could find at a decent price. They don't rate as well in the RR testing compared to GP5K tires, but for a climbing setup and for day-to-day riding, they've been fine for me.

Def need to be super careful during install. Keep levers away from the tubes as much as possible.
-
So, I run RideNow TPU tubes, and I just discovered something rattling around INSIDE MY TIRE. I thought my hub was having an issue, but upon more careful inspection, something is loose inside my tire and tube and tumbles through the tire as it rolls. I almost can't believe it. It must be some part of the valve. I can't imagine it could be anything else. But, seriously, how?! The tire is fully aired up and has been holding pressure like normal.
-
from my experience RideNow TPU inner tubes are very reliable only in the plastic valve version.
The alloy valve after few rides starts to lose air, especially with vibrations. I realized this on gf Strade Bianche where I had to stop to change inner tube because it was leaking. And the spare one lasted 3 rides more. Avoid the ones with alloy valve!
-
In my experience, the problem with 99% of TPU inner tube is the valve, ever!
Too much leaking, no matter the brand.
In order to compare, I've tested against CONTITUBE butyl (Continental) and the valve it's infinitely better than all TPU brand that I've tested.
Example:
- TPU 90 PSI --> After 5 days they lose +- 10 PSI
- Contitube 90 PSI --> After 14 days they lose +- 5 PSI

Same with latex tubes I justs check before every ride.
Ridenow do metal valves now, but I have not tried them myself
-
I believe I ordered them from several brands from AliX, used them on different brake setups (rim brakes, disc brakes), different tires and widths (25 - 32), not a single issue.
-

I agree. Recently experienced leakages with ThinkRider and Cyclami TPU tubes.
They have a similar valve core design, I noticed that the valve could be threaded in further - which seems to improve the leakage.
Anyone else noticed the same with ThinkRider and Cyclami?
-
I've been using old Cyclami TPU tubes with the entirely threaded, metal valves. They're about 2 to 2.5 years old and about 2,500 km (I don't ride as much as I should)
I have a stash of RideNow tubes as backup but haven't ever had to replace the originals.
Anyone know of there's a shelf life of these?? I doubt it (hopefully).
-
I've been using a pair of RideNow 24g TPU tubes with clear plastic valve stems in a pair of 28c tyres. They've been great, they hold air really well.
I'll have to reconsider my strong endorsement of the 24g RideNow TPU tubes. One tube of the two tubes I installed developed a slow leak after about 200-300km.
-

I just had to replace a 24g RideNow tube after a day of use. I suspect I ran over glass as I went through 3 tubes in 2 rides until I found the offending piece of glass had actually remained in the tire somehow. So, I can't really blame the tube. BUT I noticed a bubble had formed near the valve stem where the tube was trying to stretch its way out in the space between the rim and the stem. Clearly, the tpu is just a little too thin to stand up to anything but absolutely perfection in terms of rim, tire, or anything else you send at it.
It was one of my last remaining 24g tubes. Most of my tubes are 36g RideNow's but I had 1 or 2 hanging around from an old order.

I just got order of 4 Ridenow 36 g tubes. Previously had 2 that held up at least as well as butyl tubes. These 4 have the ally stem. 4 for 29.95 usd.
-
I haven't had good luck with RideNow TPU tubes. The 19g ones would go flat if you just looked at them wrong and the 24g ones would last 1-2 rides and then go flat without and obvious culprit. I might try the 36g ones in the future. I wondered if the 19 and 24g ones were just too thin. Or maybe that plastic valve is no good, I'm not sure.
-
I have had the same two RideNow 36g tubes in my wheels for over a year now.
I would guess ... dunno ... certainly over 3.500km, probably more.
They work great for me so far.

I've have very good experience with the RideNow 36g tubes. I only ordered the 24g tubes once. One failed from a confirmed puncture and the other just the other day from a puncture or maybe that bubble I experienced. Either way, I'm not that concerned with saving 12g. The 36g ones are perfectly lightweight enough for me and I've had good experiences with them.
-
I tried Boostor TPU tubes (1000 km with them).
So far, so good. No problem at all.
They hold air very well even if I don't ride the bike during one week.
I think that they are thicker so stronger.
https://a.aliexpress.com/_EwHdetM
-
my preference has been the RideNow TPU's with the alloy valve stem. i typically ride tubeless but have ridden extensively on those also without a problem. i also used RideNow's with the white plastic valve stem. they were a bit more hit and miss.
-
I'm using TPU tubes starting from the release of the Aerothan tube.
bought 2 of those and got a snake bite, this was the end of this tube because the instructions from Schwalbe where not right for the repair.
then I found the very initial RideNow tubes and started to use the 36gr version with black valves. those where mostly fine but one valve head simply blew off, luckily I was off the bike at that time.
I tried the green TPU's as well but those where rather weak at the valve stem, hence I stopped using them.
The purple TPU's with golden valves where quite good but I felt them being heavy and I did not like the valve head.
Now I'm back to RideNow 24gr with metal stem, which are now also available in black. not the cheapest but I'm very satisfied with them.
Only draw back is that start loosing a bit more air after a couple of thousand KM's and hence I replace them after 5000km.
-
I got fed up with tubeless on my roadbike, so I just ordered some Ridenow 36g tubes.
-
I am sold to Boostor, after using Tubolito (early adopter, expensive AF) - and all versions of RideNow.
Both for my road (28 and 30mm tires) and for my gravel (my gravel is in fact a sort of all road ... 42mm tires).
Why?
- they are slightly thicker: keep pressure better and resist better to punctures (in fact, a single puncture since spring, and that was due to my mistake - snakebite because I didn't check the pressure, and went through a tarmac hole, while the pressure was too low).
- they have metal valve with removable core.
- the weight penalty is 4 or 5 grams over the latest standard version of RideNow - almost insignificant.
- very good reinforcement at the valve - tube junction.
Cons:
- their tube for gravel covers 32-43mm. For recent wider tires, might not be enough?
- they are quite pricey for Aliexpress standards: pretty much like the latest generation of RideNow.
- if only, in this money, they would come with some patches, as RideNow does....
As a general impression: TPU tubes seem to be great for higher pressures, not so great for lower pressures. Quite vulnerable to puncturing when they're not inflated towards the upper limit (at least compared to butyle, where the increased elasticity of the material might help).
I've stopped riding CX for two years, otherwise I'd have been very curious to test them in CX races (Tubolito proved unreliable - a significant number of punctures)... but CX is standard tubeless territory anyway.
BUT.... I'll test these Boostor in winter, for track cycling... let's see how they handle really high pressures on 23mm tires :).
-
No one mentioned another brand called Spingo. Those are thicker than any other TPU tubed and much more puncture resistant. As a result they are also heavier around 45 grams for 80mm valve. The RideNow are 36g.
This is the only TPU brand that I had no flats, yet. Every other brand including RideNow, Cyclami, OffBondage, ThinkRider I had flats or slow leaks or got destroyed during installation because they were too thin. The Cyclami and ThinkRider had poor quality valve base and leaked air from where the valve was attached. It also be noted once they have a puncture its better you throw them out as the repair kit patches don't hold well onto the material and eventually start leaking air.
Also if you are on gravel these will go flat. Good for road use only. For gravel I am tubeless for life.
A link, please for these Spingo? They seem similar to Boostor.

I used this RideNow TPU.
just yesterday I ordered 2 of these in the "gravel" size -- 45g, for tire width 32-47. These will just be saddle-bag backups for 35mm tires set up tubeless.
Previously (and paired with GP5k 25m clinchers) I have found the best success with the much-lauded "off bondage" purple tubes with the brass-colored metal valve. But I haven't seen that variant in 'gravel' sizes despite much searching on AliExpress, so back to RideNow it is.

I have a few of these that I use for the same purpose. Unfortunately, for me, they're essentially "single use" since I'm otherwise tubeless for my gravel bike and there's no way to really pack them back up into the same tight, small size to fit back in the seat bag. I've had to use one when I split a tore a sidewall and it wouldn't seal, but then when I replaced the tire I didn't need the tube anymore so it sits on a hanger in my garage waiting for a big, non-tubeless tire to go into.
-
Received my 5 Meroca tpu tubes today, orange, 80mm valve, paid 2,39 per piece, 28g. Will try them tomorrow.
-
I've decided to give a second chance for those TPU inner tubes, and for my surprise I've found a good one: OFFBONDAGE (Purple)
Riding some hundreds KM in ROAD (700x28c and 700x25c) and GRAVEL(700x47c), this TPU it's very good. A little heavier than others brands, but less valve leaks and replaceable air core.
If the price hurts a little bit, my second choice would be X-Tiger (green).
-
I've had no issues with the cyclami tubes with metal valves. Ridenows have been fine for me, too. OFFBONDAGE I only tried once and it lasted about as long as expected.
With ThinkRider tubes, I've had the little metal ring holding the valve core on get stuck in my pump. The first time this happened I didn't notice it and the valve core flew off on a (luckily) slow descent.
A buddy of mine also had RideNow tubes fail on a long and steep descent (Männlichen in Switzerland) using rim brakes. There was no hole, so we're assuming there was some glue keeping the valve attached on that melted.

Did the plug Streets of Mesen (from the Gent Wevelgem classic) which has lots of small stones, also a bit of gravel with my roadbike and these tpu tubes, No flats. So they are not more vulnerable than butyl tubes imho, all depends on the tire (continental gp 28mm zit thé moment)
-
Just want to come in and re-extol the virtues of my older Ride now (classic?) tubes. The older 36g ones with the plastic valves. I've had a rash of broken spoke nipples and other wheel issues. I've had one tube that I swear has been removed and re-installed about 4 or more times now over the last 800+ miles and it's been fine. I used to worry about how delicate they seemed and would fret over pinching them on install, but I guess I don't need to worry so much.
I just had a broken spoke nipple fixed again on that wheel the other day and finished up a ride on it today with that same reused tube so it was fresh on my mind when I saw this thread again.
-
I stopped using TPU tubes on all but one bike. If you have tubeless ready wheels, I would just go that direction. You still have to tape your rims with TPU tubes, so might as well go the extra step. TPU tubes are not bullet proof and they're still a pain to patch and not guaranteed to stay on especially if you live in very hot weather.
The one bike I'm using TPU tubes is on my daughter's 26er. The wheels aren't tubeless ready and I think for wide tire applications they are okay, since not so much air pressure is needed. The TPU material doesn't need to be stretched out thin, making them more durable. Also the weight savings is quite good over butyl and latex. I find air pressure holds better on wide tire TPU tubes. When I was running road TPU tubes, I had to pump them often.
I'm running 25c tubeless and comfort is very similar to 28c TPU tubed, but with the lighter weight and quicker acceleration of the narrow tire. Also some brands are easier to mount narrow tires like Panaracer Agilest and the Schwalbe Pro One tires. I haven't tried the newer GP5K 25c tires, but I hear they're easier to mount now.

I've been running the clear plastic valve ones since 2023, somehow haven't managed to puncture yet and my pair have lasted well over 10000 miles. Maybe it's my tire choice (GP5k's, now Pirelli P Zero RS Clinchers), but they're awesome.

ridenow and cydi for more than 14000 km this year! both are fine! no problems...
-
Received my 5 Meroca tpu tubes today, orange, 80mm valve, paid 2,39 per piece, 28g. Will try them tomorrow.
how did it worked out for you? the orange meroca tpu tubes were the best i ever had, almost zero pressure lost in 1 week.
-
BUT I noticed a bubble had formed near the valve stem where the tube was trying to stretch its way out in the space between the rim and the stem. Clearly, the tpu is just a little too thin to stand up to anything but absolutely perfection in terms of rim, tire, or anything else you send at it.
When I worked at a shop (decades ago) I'd see this with latex and butyl tubes as well. Sometimes the valve isn't pulled all the way to the rim and the tube will develop a "bubble" in that space.
-
how did it worked out for you? the orange meroca tpu tubes were the best i ever had, almost zero pressure lost in 1 week.
To be honest, I think I lost about 1 bar in a week after 13 hours of riding. A bit more than with butyl before, but normally I always add a bit of pressure before every ride, now I didn't, just to check.
-
I've used TPU tubes for over a year now and have found that I have no issues at all with the 19g RideNow tubes on wheelsets that have no holes in the rim bed, but have had issues with them on wheelsets which use rim tape.
I only use the heavier/thicker 30-40g TPU tubes now on wheelsets with holes in rim bed/rim tape and have no issues at all with punctures.
-
I just caught a flat on a Ridenow 36g tube this weekend. I'm pretty sure it was on a spoke hole. I might try tubeless again
-
The second of my 24g Ride now TPU tubes with the clear plastic stem was losing pressure overnight, so I tried replacing it with one of my spares.
The spare had a leak straightaway. I take care and follow the instructions carefully when installing TPU tubes. And I had already checked the tyre for any sharp bits. No tyre levers were used to install the new tube - only to remove the tyre from the rim seat so I could remove the old tube.
Then I repeated the process with my last spare 24g tube, and with exactly the same result. That's 4x 24g RideNow tubes failing all within the space of a few weeks. A bad batch?
I have now been running the Offbondage TPU tubes with the part black and part silver color stem for a little over a month on this bike with no issues. I've used them before on another bike for well over a year, also with no issues.
I'll stay away from the 24g Ride now tubes with clear plastic stems from now on.

Does anyone has experience with PINMOAP tpu tubes? Great price - how about quality?

no luck with original ridenows white valve on gravel but ok on road.
find if you hav them installed on a tyre and go to change same tyre ,slightly inflate as normal but can rarely if ever get them to behave on install as tey would originally.
could start my own tpu factory here! - so many punctured hanging on wall!
Can anyone share on how to repair a punctured tpu
I have two ridenow patch kits with hobson rubber cement ??
thinkrider out of the pack wont hold air - absolute shite.
off bondage purple black threaded long vale with valve wheel holder.Bought three
2 punctured/lost air very easily on install - i did take extra care but no difference wouldn't hold air - factory defect .
were 4.89 each now 8 e each - junk.
i need a viable alternative.
cyclami seem to be good.
Gustavo ?
help me obi won!
-
I use gustavo on gravel. Quality is fine, have had no issues with them. I usually pay around $10 for 2. Have stocked up and should be good for quite a while. Have only had 2 punctures, they were both on the same day from the same piece of glass that embedded itself in the tire.
Bought 1 cyclami and it came with a faulty valve connection and wouldnt hold any air. Others may have had better luck than i have.

So far, I've only tried patching RideNow TPU tubes. If the TPU tube is really old or has a dodgy valve, I wouldn't bother trying to patch it.
But what worked for me: Cut out a small patch from an old tube and glue it on with 'CAMPLAST - Cement' glue (pretty cheap and strong stuff) and put a heavy book on top of it. After letting it dry for a bit, I put some more glue around the edges of the patch. Don't know if this is the best method, but it doesn't take a lot of work, and I haven't had a problem with those tubes so far.

ok so gave this a go from YT video option 1
New black metal valve purple offbondage TPUs and disappointed when got two slow air releases out of the box post install.
i think rim tape is key for any succesfull TPU install tbh especially on hooked rims with spoke holes.
so used ride now patch kit on the OB TPU and plenty of glue went on ,then apply the RN TPU patch and 24hours later with some weight on it,seems to have done he trick so far.
pumped up 10psi approx and leave hang in shed for a further 24hrs to be sure to be sure.
