UNCATCHABLE leaks of RideNow TPU tubes

[@ZavyalovCycling]

UPDATE. All 4 out of 4 MTB RideNow tubes that I ordered suffer from this problem! They all leak air from 30 PSI to flat within 24 hours.

[@phoffen3829]

That has been my experience with road tubes (28c tyres) although it takes longer than 24 hours to go completely flat, they lose air pretty quickly. I am going to have to go back to butyl. Too bad because they ride great.

[@DavidSmith-hz3jg]

​​@@phoffen3829I ordered the NEWBOLER ones on Ali express because of the great reviews and I have them a month and haven't noticed any loss of air whatsoever and I only ordered 2.

[@thejuampi]

The Presta valve on your bike tire features a small, threaded nut at the top which is essential for inflating the tire. Before inflating, you need to unscrew this nut to allow air in; don't remove it, just loosen it enough. After reaching the desired pressure, tighten the nut back down to seal the valve and prevent air from escaping. This mechanism ensures a secure seal to maintain the tire's pressure. Always make sure the nut is tightly screwed after inflation to avoid any air leaks.

[@JAYFLATLDN]

I got 4 tubes 20". All 4 are extremely hard to pump up (it's like I'm at 120 psi from the get go) It's a problem with the valve on the tube and not the cores. Even when I remove the core they deflate at a extremely slow rate. Sort it out RideNow

[@edgardoroxas1324]

It's hard to find leaks on a TPU tubes because you can't put enough pressure to actually find such leaks. Put little pressure first on it, put it under water, then try to locate the really minute leaks. I had to manually squeeze and stretch the plastic film about 3 inches at a time. The leak I found was so minute that it releases such fine bubbles.. It appears to be normal to lose pressure after 2-3 days.. hope it help somebody out..

[@Agiyi]

This is the happiest and most excited person EVER who has an undetectable slow air leak on his inner tubes...

[@veganpotterthevegan]

Someday, I hope to be happy about a leaking tube just like he is. He's happier about his leaking tubes than I am about my setup that's not leaking air. It's sad😢

[@comedyman112]

i like how you present this annoying issue with a big smile on your face 😄 I've used both 24g and 36g road tubes and never had this issue. just the problem of easily puncturing from the smallest of thorns

[@ZavyalovCycling]

Hi! As I’ve mentioned earlier, none of my road RN tubes has been affected by this issue either. Even after a year of use. But all of MTB ones have failed exactly this way 🤪 Lottery!

[@IvanMalechko]

I have RideNow in my 28mm road wheels and in 40mm gravel set. Zero issues, hold air for weeks, much better than regular tubes.

[@ZavyalovCycling]

Could say the same on my road RideNows. Zero issues. However, it’s just the opposite for all 4 ordered MTB 29 inch tubes. All 4 are leaking. 100% issues 😂

[@IvanMalechko]

​@@ZavyalovCycling Well, I guess I've just been lucky so far. And you seem to have the clear valve, so it should be the newer 'updated' version. Hopefully, they will fix it soon. I would also assume that RideNow doesn't offer any customer service to handle replacements... Not as expensive as tubulito but not too cheap as regular ones, 4 Ridenow tubes would probably be priced about as a good new tire. Despite these potential problems, I'm also not yet sold on the tubeless mess and still prefer tpu.

[@daneilsteenkamp6886]

I tested ride now tires. I really love the ride feel. I thought I punctured all three in a period of 2 weeks. And was perplexed that I did not find any damage to the tyre, or objects in the tyre. Even bought a new tyre. Also found numerous small leaks in the tubes. At first I was impressed that the "punctured" tubes held pressure for so long. Sadly, the last leak was on my front wheel. It caused me to crash and crack a collarbone. Again, no damage or debris in the tyre...

[@terryduncan8979]

I started with 2 RideNow (race formula) 45g tubes w/SV45 valves - claimed on the box to fit 32-622 to 47-622. The first 2 ordered hold air fine in a 28mm width Conti 5000 (1week and more starting at 70-75psi, and not decreasing below50psi). Awesome! Ordered 6 more and so far the 1st 2 go pancake flat in 36-48 hrs in 40-622 gravel tires at tests up to 45psi. Under water testing indicates several/many tiny slow pinpoint seeps from a tube inflated just enough to be smoothed without being 'stretched', sometimes the bubbles are grouped. It seems probably the TPU becomes thinner at larger diameters and may become very slightly permeable. Individual tiny bubbles can take 30 seconds or more to form, and are more readily noticeable if the tube gets any slight fold/kink from bending it into the water bucket. Proper leaks are a stream of bubbles.

[@ZavyalovCycling]

Yeah, this all sounds extremely familiar! A typical story with RideNows, sadly.

[@props651]

I had the same experience with these tubes along with WTB's tpu tubes. Thie first time, I threw in a Ride Now on my gravel bike in the middle of a race. It held great for the remainder of it. When I went to clean my bike the day after, that tire was completely flat. I reinflated it and it lost a lot of air in a couple hours. I checked for leaks and saw none at first. I checked again the next day and discovered a bunch of really tiny holes. Very very small. About 7 of them. I wondered if it chemically reacted with the residual sealant or if the friction between the tire and the tube was the cause. The WTB's did the same thing. I bought them because they were cheaper than the Aerothan's I ran. I compared the Aerothan tubes with the Ride Now and WTB's. The Aerothan tubes are thicker and feel much more durable than the alternatives. But at a cost. I've never had mystery leaks with the Aerothan tubes.

[@ZavyalovCycling]

Thank you for the feedback! In particular, for mentioning the residual sealant fact - exactly my case. Even though I did my best to clean the insides of the tyres, some tiniest bits were surely left. Some TPU tubes might not chemically stand it, indeed (though they should).

[@robertvsnow]

I've had good luck with RideNow tubes. My only problem came when using 36 gram tubes with 32mm cyclocross tires. One tube ripped at the band that connects the tube together and the other had stretch marks at the band. It was clear they had stretched too far. I switched to 45 gram gravel tubes and have had no problems. My experience with 25 and 28mm tires with 36 gram tubes has been great over more than a year. Also no problem with 45 gram tubes in 38mm gravel tires. For me, they hold air much longer than butyl. I had one puncture with a small thorn and the supplied patch developed a very slow leak after a few days. The patch peeled off easily and I applied a tiny drop of gel super glue to the hole before applying another patch and that has held for months. All of the tubes had the clear, rather than older black stems. They just introduced new 39 gram all-road tubes for wider tires. My advice is to go as heavy as will fit in your tire, because TPU does not like to stretch.

[@juliovergaram]

I bought the gravel version (claims to go up to 47mm) for a 47mm tire and they lasted less than a week. I have the same suspicion as you do. I will probably try the MTB version so they don't stretch as much.

[@BigFarm_ah365]

That's why I'm here. Put air in, tire is flat. It was the first thing someone said to me when I mentioned them. I could deal with inflating them every ride, but it's gotten worse

[@benson475]

This looks like a commercial video for Tubolito. I am Riding the RideNow tube with 120 PSI and really love them. They seem to keep the pressure better than rubber tires. On the other hand friends who tried Tubolitos all have had issues with the valve.

[@Nivacromcolumbus]

Still riding ok,? Just bought some ride now 36g

[@carlsherratt3432]

​@@NivacromcolumbusI've not had a single good Ridenow tube, all going down over 24 hours, suspect serious quality issues in production. My cheaper unbranded tpus from eBay are better, wish I'd seen these warnings before buying ride now:-(

[@fredpomi851]

Tried RideNow a month ago with two gravel size tubes (to go in 40c commuter tires). No leak whatsoever and pressure is maintained for almost as long as with butyl tyres. That got me really excited and I ordered 3 tubes, MTB size to fit my 50c gravel tyres. No problem on my few first rides, then the front tube started to leak slowly (flat in about 24hours), no visible leak in water (?!). Very puzzled, I then decided to use the 3rd tube to replace it. The 3rd tube had been sealed half way where the two ends meet and couldn’t even be inflated at all. I fixed the holes with RideNow TPU glue (no air leak in water) but the tire still leaked under pressure, I then found 2 tiny random holes which I fixed with self-adhesive patches. Checked the tire again in water, mounted it, got flat in about an hour 😢 I am giving up on the MTB tubes, I wouldn’t even trust them as spare before having checked each of them in real conditions.

[@ZavyalovCycling]

Hi, Fred! Your experience goes hand in hand with mine. I've got a couple of road sized RideNows (black plastic valve stem), and they are absolutely fine after a half year. While all four of my MTB purchase (semi transparent white plastic valve) are leaking. Unfortunately, this means these tubes cannot be trusted in general. Some are fine if you are lucky, but that's not to be relied on.

[@fredpomi851]

I had a left-brain idea last night: to put sealant in the tube and see what happen (I was expecting a slow milk seepage through the walls of the tube, worse case scenario). Unfortunately, the valve core seem to be bounded to the valve stem… Too bad 😢

[@Neo_The_One_]

Just intalled one in my front tire. Only issue I had was the schrader valve was not tight out of the box. Cause a slight hiss/leak. Tightened the valve and all is good now.

[@raysmith2602]

Ive thrown 3 of them away due to holes from new and leaks at junction with valve. However Cyclami tubes have been trouble free

[@ZavyalovCycling]

Road or MTB Cyclami, Ray?

[@FJJ18]

I just had this happen to me after putting Ridenow tubes in my gravel bike tires (650b 47mm). One of them was fine, the other one loses pressure slowly over a day from 35psi down to really soft. But I can't find any leaks using the water test, and the lightly inflated tube seems to hold air just fine outside the tire. Very strange. I'll keep it though as an emergency spare.

[@ZavyalovCycling]

I already have one more MTB RideNow with this problem. Looks like a trend, sadly!

[@vurom]

Same problem, bought 2 tubes for my road bike, pumped at 60-65 PSI, one tube still holds the air after 4 months of usage, one tube went flat after overnight after 1st ride, and still can't find the puncture or leak. So RideNow brand tubes are just randomly working, I think. If you are lucky, you get the good tube otherwise, once it's flat and can't find the leak, pretty much goes to the bin.

[@ZavyalovCycling]

💯

[@cyclingSausage]

I've used two RideNow TPU tubes now. The first I had fitted for a couple of months and it developed a pin hole puncture on the inner side for some strange reason. The next one I fitted leaked from two places where the valve attaches to the tube. It's back to butyl for me, but I'll keep a couple of TPUs as spares as they don't take up much space in my saddle bag.

[@klcbsoft]

Ordered 4 RideNow, 28g tubes, installed on the roadbike, inflated to 6.5 to 7 bar, went for a 80km ride, all went well. Next morning: both tires flat, not quite flat, some 0.2 bar were still in the tubes. Installed the second pair and exactly the same happened. Actually a bit disappointed after all the hype about RideNow. Guess quality control is still kinda flakey in the ppls republic.

[@ZavyalovCycling]

Sounds exactly like the story with my 4 MTB RideNows 😂 Tubolitos are much more expensive, but in the long run a choice of them could be actually cheaper 😂

[@conceptcs]

My experience with RideNows. I got their 36g 700c tubes for road bike. First two inner were amazing as I'm coming from 100g+ butyl tubes. Presuure leaked from 80psi to 60 overnight and stays there. I broke the valve on my rear wheel as was trying out my new hand pump. Third tube installed but cannt hold pressure at all, pumped to 80 and is sitting at 30 overnight. Put it in water and no visible bubbles. Im going to try the cyclamis in the future.

[@ZavyalovCycling]

To sum up the reviews and my own experience, the RideNows are a lottery. You can be absolutely happy with a couple and absolutely furious with the next dozen 🤪

[@fjp2000]

I have the same problem now with the 3rd of my 10 tubes. Its a desaster. Some of them dont leak yet but have a defect valve, where the air will not go in freely and you cant check the air pressure.

[@ribatalgozi9570]

My experience ridenow have 2 type valves, the black one and the white one, on my case the white one always have slow leaking isue but the black one has no isue

[@thejuampi]

14 months here riding RideNow TPU tubes, have no issues so far. Remember to adjust the presta valve after inflating

[@Honir4]

I had the exact same experience. I was so impressed with the first batch of tubes I bought a second batch of 8 tubes as spares and for my other bikes. I have used 6 of the 8 new tubes and they all leak.

@drooghead it's pretty annoying, I did contact ride now about it , they did replace the tubes, just had to send them proof they were faulty, fingers crossed but the first two iv fitted are still up

[@johnpowell9174]

I've had a slow leak from a Tubolito inner tube. Despite trying my best, I can't find the point of leakage. The problem, as you point out, is that TPU tubes can't be inflated to sufficient pressure to be able to find the source.

[@johnpowell9174]

I am going to put some sealant into the inner tube, it's all that I can think I can do.

[@SkipperTyrrel]

Yeah same here, two tubes doing the same. Both inflated and flatbwithin hours, but cant find a leak anywhere. The one I have in my front wheel is fine. They may be cheaper but if I have to buy twice as many to get one that stays inflated then it's the epitome of buy cheap buy twice

[@DirtRoadie]

Invisible pinhole leaks seem to be common. One of my Ridenow MTB tubes seemed to hold air well for months of use, but then developed a slow leak. I found no damage, but was eventually able to identify EXTREMELY small and hard to find pinhole leaks. LOTS of them. So small that, even with the tube inflated fairly firm, it would take would take 10-20 seconds or more for a smaller-than-a-pinhead-sized bubble to form when testing the tube underwater. Nothing resembling an obvious stream of bubbles. Most of the pinholes were on the inner/rim side of the installed tube. It's hard to know whether those holes developed in use or if they were always there. Interestingly, in my chasing after these holes, some seem to be intermittent. But since some TPU materials have a "self healing" characteristic, it leaves me wondering if these tubes may show a similar behavior. But ultimately, the real significance is the sheer number of holes. While clear non-foamng Gorilla glue is suitable for patching these, I'm not sure the required labor and time to locate, mark and patch all the holes can be justified. On a more positive note, I have had no issues at all (and no flats) while riding. And no problems at all with Ridenow road tubes. Nonetheless, I'm going to be trynig some of the other brands.

[@ZavyalovCycling]

A similar story. Road batch - 100% fine. MTB batch - 100% shit 😂

I has same problem with Pirelli smartubes, but once while being around the bike the valve just started leaking air in small bursts!!! Worst of all this same situation where the next day the tubes appear totally flat had ocurred with at least 3 different ones of the same brand!! Really scary and dangerous, so now Im back to butyl

[@ZavyalovCycling]

Quite surprised with your Pirelli experience! Have not had anything like this with Tubolitos. Thought all top range TPU tubes were free of this.

[@m97120]

I have Schwalbe TPU tubes that are also leaking. I found in another article that it might be the plastic valve that might be causing the pressure loss. I'm probably switching back to butyl. It's very annoying.

[@jefmichel2302]

I have this problem with one RideNow TPU tube. I was hoping you had the solution! Water tests do NOT show any holes. Very frustrating. I will keep it as a spare, since the leak is so slow. One thing I DO like about these tubes is the WAY they handle thorn punctures. I picked up two massive goatheads about 3miles from home. I didn't pull them out, as that typically means an instant flat with butyl tubes. I left thorns in and rode. Thorns eventually broke off. Still held air. Got home, still had plenty of air in gravel bike. When I pulled tube to find holes for repair, I couldn't! I HAD to put tube in water to see any air leak. It's as if the stretchy material nearly sealed itself in the same way a whoopie cushion does. Even knowing where the hole was, it was super hard to see it and hole was caused by a BIG thorn. Anyway, I suspect these tubes will allow me to get home or finish rides that I otherwise wouldn't. Of course I'll find bike with a flat tire the next time I go to ride, but that's ok. I'm super impressed with the RN tubes. Light and inexpensive, with finding a leak the only downside. I'm sure Tubolito tubes are good, too. All of these are so much better than the Panaracer urethane tubes I tried in the 1980's. I'll post a video if I come up with a method of finding punctures.

[@cornelhughes]

Admittedly a late reply but its best to use soapy water, and then look for bubbles

[@stinkybeam]

yes, this is the exactly my experience, I bought 3 of them, 2 of them leaking, but I couldn't find any leaking spot on the tube before installing the tube. It hold the air after fresh install, but not anymore after a 50-60km ride, it lost all air the day after the ride. 2 of the new Ridenow tubes had the same problem. Then I bought a different a TPU tube from different brand, not more leaking.

[@cornelhughes]

what other brand did you buy?

[@joninoj214]

RideNow Tubes have random quality issues to my experience. I've had this problem too. I've also experienced tire blow when running over a small pebble. Patch kit also leaks after a while so I don't bother. When it's good it's good for weeks. Try your luck.

[@ZavyalovCycling]

Have not yet tried the glue from RideNow patch kit. The packaging says “rubber glue”, while TipTop provides “Camplast” glue for such applications. With this Camplast glue, my patches of RideNows are reliable so far. In general, yeah, RideNows are a lottery. Some tickets win, while others - lose 😂

Yes slow leaking from the valves 😢

[@jaysonbuenaflor1094]

I experience the same thing and found the small leaking spot on the connecting area of the tube. It still looses pressure of about 20 to 30 psi in 24hrs.

I had a strange experience with RideNow TPU tubes on my road bike. They worked great for 3 months then I got a puncture. I easily found the hole visually as it was large. Patched it with no problems. Then I got a slow leak with another ridenow tpu tube. For the life of me I could not find the leak even under water and pressure. The small pinhole leaks are impossible to find.. I then put this tube on another wheelset and now it holds air with no leaks. So with one wheelset it leaks and on another it doesn't. But when I ride the bike it leaks slowly. So the leak only occurs when fully inflated and while being ridden. very weird.

[@cornelhughes]

Have you tried finding the leak using soapy water? The idea is you look for bubbles, with tube inflated, in each area after taking the tube out of the soapy water solution

[@parmijo]

@@cornelhughes Yes tried soapy water. The problem is that TPU tubes can only be inflated up to 8-10 psi when not installed on tire/rim. If you inflate them higher to find a leak it will permanently distort the shape of the tube and ruin them. So I just run sealant in my tpu tubes which will seal the micro sized hole.

[@montrose252]

I have had this problem too! But I do like riding on RideNow tubes.

[@ZavyalovCycling]

Agreed. Have zero complaints on my road RideNows!

[@BostilCensurado]

I have one right with such a micro puncture, i'll put soap all over it and leave it be to see if foam forms anywhere over time. Also dont buy the new ones with a plastic stem, they bend and break , and dont use the caps on the ones with aluminum stems because they oxidate and fuse themselves to the inner core, you will never be able to take it of without breaking the stem. I like tpu tubes but think they should be cheaper considering these kinds of problems, and butyl tubes sometimes also cant be patched no matter what.

I bought 10 TPU from AliExpress. But 3 of them are leaking at the valve between the valve core and the black tube.

I think it is hit or miss, good batch or bad batch. What bothers me the most is I don’t feel to have to mount a spare TPU to be sure it is OK.

If you can locate a puncture, it can be fixed quite reliably. But for a permanent fix my advice is to use a TPU patching kit with GLUE. A self-adhesive patch will likely fall off in a while. Just a temporary solution.

@@ZavyalovCycling ridenow road tube. No puncture, inflated fine by the roadside, but just went flat while on the bike. Really weird. I have another that's fine, but wouldn't buy again.

[@mikefoster3901]

I've gone back to latex tubes

[@housepfhoopz]

i have had same issues with tubolito with their S-tubo lightlest version i noticed rim bed imperfection can cause these pinhole leaks i actually had to stop buying the ultra light version of tubolito s tubo to prevent these problem

[@ZavyalovCycling]

I have S-tubos exactly in my road tyres now, punctured and repaired aproximately 10 times in total. I had the rim bed puncture around a spoke hole (through rim tape) which you mention. Though, just once so far. In comparison to RideNows, quite happy with S-tubos and their repairability. In the long run Tubolitos are cheaper then RideNows, it seems.

[@housepfhoopz]

@@ZavyalovCycling ya i went back to using the thicker Tubo for backup since i need my spare not to have pin hole as soon as i pump up to pressure

[@thispod]

Good thing I ride tubeless and got these only to save the day in case of serious tyre damage

[@goffl8644]

Any new word on solutions to this?

[@ZavyalovCycling]

Sadly, no. Some slow leaks on RideNows are just GHOSTS 🤪

[@robertstan2349]

for emergency use. i just need to get back to the car. as long as it does that, good enough for me. otherwise, standard tubes with some slime thrown in.

[@dsonyay]

Might be you have a bad rim tape and a spoke is cutting the tube?? Four tires doing this is not usual

No issues with my Tannus Dubied Mountain TPU Tube 29" x 2.0"-2.6"

[@bryanh9288]

no issues with my ride now 29" tubes

[@ZavyalovCycling]

Nice! Which color are the valves on your 29" RideNows?

[@bryanh9288]

@@ZavyalovCycling clear/ but they look white. the valves cannot come out of these like others that i've heard. unlike yours my actual valve is black, where yours is silver

[@alexdcpe]

Exact same problem for me! 26/27.5x2.2 tube version, the ones with the white valves.

[@ZavyalovCycling]

Thanks for one more proof their production and quality standards are so far from acceptable right now 🤪

[@janberglund9398]

I have mixed results. The 26/27.5x2.2 caused me lots of pain. One of the tubes I stopped using , it just leaked too fast. The other one looses pressure but not so fast it impacts a ride. I did find some bubbles, using the water test, and applied the patches but seems to no use. Now to the 700 tubes. I put them on a road bike and they work perfectly fine. I am not sure that is wrong with the 27.5 but given the dual size 26/27.5 one could theorize that the tpu gets too stretched when used on the 27.5 wheel.

[@SkipperTyrrel]

It's the ones with black valves for me that are the problem. Consider them a waste of money.

[@sylvainbernaers]

a piece of teflon tape and scew the cap on. problem solved. it is leakage from the valvecore in 90 percent of the cases

[@dsonyay]

Yeah I would reuse that deformed tube.. on a mtn bike.. no big deal. But unfortunately, you have a leak that you can’t find, until then I guess you really can’t ride it

[@jonboey3246]

the most useless purchase i'd ever made! back to butyls.

[@As2ronaut]

Nice acsent Володимир. No one in their right mind uses any tubes on 29 wheels.

[@nofood1]

The worst tubes in the planet. Save weight with titanium spokes and carbon rims …. THIS IS NOT WORTH THE HASSLE
