Tubolito's New MTB PSENS Tubes Have a Built-In Pressure Sensor

Apr 22, 2021 at 14:41
by Mike Kazimer  

Have you ever wished your phone could communicate wirelessly with the tube in your tire to check the air pressure? What if that tube had a super catchy, and definitely not chuckle-inducing name like MTB PSENS? Same here, but Tubolito's latest addition to their line of lightweight tubes is actually a pretty clever innovation.

The Austrian company has put a NFC (Near-Field Communication) chip that's encased in foam inside their thermoplastic polyurethane tubes. The chip wirelessly sends a pressure reading to the Tubolito app when a smartphone is held against the tire. The chip doesn't require any batteries, and only adds around 7 grams to the tube. It's located around the valve stem, which makes it easier to remember where to place the phone to check the pressure.


The MTB PSENS tube has a 42mm presta valve and is available in 27.5” and 29” diameters. Claimed weights range from 90 – 93 grams, although my sample actually came in a little less, at 86 grams for a 29” tube. Even with that NFC chip, that's still significantly lighter than a standard rubber tube. The $49.90 price tag will also leave your wallet a good deal lighter than a traditional tube.

I installed a MTB PSENS to give it a try, and can confirm that the technology works. Once I opened the app and held my phone against the tire the pressure would show up in a couple of seconds. I did run into some little bugs with the app – at one point it kept showing the previous pressure reading until I exited and restarted it, and a few times an error message showed up and I had to scan again, but I'd imagine those will be sorted out relatively quickly.

A 29" version of the tube weighed in at 86 grams on my scale.
The foam pouch containing the NFC chip is visible above the valve stem.

At the end of the day, I'm not really the target audience for this tube. I run tubeless on pretty much every bike I own, which means the only time I deal with tubes is on the off-chance I need to fix a flat. In that case, I'm usually not too concerned about having the perfect tire pressure; I just want to get rolling again and make it back home.

However, the NFC technology is intriguing, especially if it can be incorporated into a tubeless valve stem at a reasonable price. We saw Quarq release their TyreWiz device a few years ago which communicates via Bluetooth, but that costs $200 and uses batteries. A quick scan of a few DIY sites brought up a concept that look promising - it'll be interesting to see where else this technology gets applied in the future. Who knows, maybe someday you'll be able to quickly check shock, fork, and tire pressures with your phone.

 So don't buy a new car, a massive house etc. One little chip won't make any difference. If you seriously want to be green first stop stuff with big impact, not the negligible.

 I’m not so sure this is any worse for the environment. I mean sure a chip is a bigger impact than no chip but dropping $50 on a tube is going to make it that much more likely to be reused. Of all the dumbass wasteful products on here seems a relatively insignificant one to take a stand on.

Like Tubolito, I will be waiting for next year's model which is rumored to have a high powered fan in the valve stem and the PSI will be controlled by the chip in my brain. So take that, single use analog CO2 cartridge. Take that, acoustic human. hashtag caveman.

 The chip could save environmental waste. Chip is a great addition to an UL tube. Using it as a fix to a flattened tubeless tire, if your bacon strips fail or your out of them, you throw in your turbolito and put extra psi in it to get you home. At home you fix your tubeless system and still have the super light turbolito to use again because it was ez to make sure you had enough psi in it to get you home. Perfect application for a light weight tube that will fail easier with too little air pressure

 Surely, when tubeless, the sealant plastic bottle is worth at least 2-3 tubolitos in mass. And I'd use at least one bottle a season between tyre swaps, punctures and sealant refreh. Been riding tubolitos front and back for a season and have yet to puncture, so it seems (and is advertised) more durable than your regular tubes and thus might not get thrown away as fast. Though, I'm sure it can be punctured and then the chip might make it hard(er) to recycle...

 @kanasasa: By no means I believe we should live carelessly. By no means I think a disposable product with electronics in it makes any sense. Especially then a removable valve would be 10 times better.

But a lot of people doing little things and it all adds up?... Hell no it doesn't add up. Covid has diminished number of flights and it had virtually no impact on total emissions. I know what you mean but you are using a naive argument. You can't believe that if you drive less world will be better, because no matter how many do it, it has far lower impact than i.e. what government can do by stopping to subsidize oil now, But that will hugely increase food prices and there are at least 10% of folks in every Western country who would become homeless as a result of this.

This is a super dumb product, such function is great to have but it should be solved as a valve thing like tire wiz. No need to hold hands and sing the song of Gaya to prove how dumb some things are

 @won-sean-animal-chin: I was running Maxxis EXO / EXO+ DHR and DHF on a SB150, Stans race and Vittoria AirLiner (both front and back but superfluous up front so I later removed the insert up front and went with a DH casing instead of EXO). Both on RaceFace ARC carbon 31 and later on Zipp 3Zero Moto. It's comfortable to run low(er) pressures tubeless with insert but it actually began to feel too soft when pushing hard in corners.

So I started cautiously with tubolito up front and Assegai DH. Worked perfectly. So I went with the back too in a DHR EXO+. Both the "plus" size tubolitos (the non-plus size really is too small for 2.4-2.5" tyres and above). As a result, the plus size tubos don't stretch as much and might then endure more abuse.

Granted, the Zipp rims can take more of a beating than lighter weight carbon rims (in which case sticking with tubeless + insert might be preferable)

(PS: no I'm not a dentist, just buy stuff only on discount and prioritize biking above all else.. very cheap car, very cheap apt, and so on...)

 @Compositepro: Population is said to stop increasing around 2030-2040. With rise of standard of living and womens education decreases will to have more than 2 kids. Consumption becomes an increasing problem though. of course all of us are consuming hell of a lot. MTB is not green in any form, especially in successful form. If you are actually good at riding, chances are: your environmental footprint is gigantic. You need to travel a lot to practice in different bike parks, and buy lots of products, you probably drive to ride almost every time.

If you ask me... I think the kids of my kids may be fkd... but i honestly don't think there is anything we can do. We are slaves to our brains chemistry on both individual, local and global level. Our only chance is for climate change to take long enough but consistently enough across the globe, so that natural disasters force policies out of pure economical point of view. We have huge capacity to restore environments but it takes time. Policies are tough to push through and as far as I hear California is a great example how wrong it can go when "green lefties" get free hands to push their BS. Low quality policies to win votes, doing more harm than good ,especially to the cause.

Just because someone says they are for environment doesn't mean they are not full of crap and should be kept from decision taking as much as possible since they can only wreck Havoc. Look at that DCA dude, he is doing more disservice to minorities he claims to fight for than good. Green lefties are at least as bad as people they criticize if not worse. I know a few folks like this working for municipality and they are resentful aholes and btches with raging minority complex being only after one thing: attention and power. "green" and "equal" are their passwords to get what they miss in their life They don't give a sht about the world.

 Thank you for saying this! This environmental disregard is a major problem in mountain biking ive tried to make comments about it before but they get so many dislikes. There is a ridiculous amount of fast-fashion and materiality involved in mountain biking. We could buy most stuff used and stop worrying about having the very best kashima koated brand new bicycle. This along with the *uh oh* environmental pulverization caused by bike parks (yes, whistler too), and to a lesser extent the disregard for the well-being of the land by many trail builders and bikers (not all!).

As for an alternative, I found three tubes that hold air in the dumpster yesterday, and this is a fairly normal find. Maybe u need to buy new tubes, fine, but there's plenty of other stuff we can buy used, or just not need to buy. ❤️

 @DhDWills: You make no sense, yet make so many assumptions. I know plastic recycling is pretty much a joke these days (and was even before COVID complicated things). But landfills filled with unnecessary plastic aren't "green".

The solution is and always has been to reduce production of waste, not just figure out what to do with it. At some point, we need to hold corporations responsible for creating throwaway items to increase profits, but given the piles of money they throw at the gov't to keep the status quo that won't change any time soon.

@rhagelaar: That was my point. It makes even less sense to pack them into individual plastic containers that'll end up in a landfill. Yet, there it was.

 Does the MTB PENIS store data too? I've firmly wondered how high psi gets when the tire is compressed in a g out but dont believe I have ever wondered quite this hard. It's an awfully stiff price though. Sounds like my opinion is flopping around here, but I just cant get my head in the right place.
  • 10 0
 @husstler, your tire pressure will increase exactly in proportion to the decrease in total tire air volume cause by the G-out. In other words, not very much. Even a huge tire deformation, like down to the rim, reduces the volume very little because its happening on a small fraction of the circumference of the wheel/tire.
The equation governing this is p1v1/t1 = p2v2/t2 (p = pressure, v = volume, t = temperature). T is constant in this case, so P1V1 = P2V2. Exact answer would require some assumptions about the tire deformation and some toroid math, but roughly speaking, a 20psi tire could increase to 21psi. A tire insert would have effectively increase this, but not dramatically, roughly to 22psi.
  • 2 0
 No it will not, since it is a passive technology, I guess similar to RFID. Which means that the device is powered by the very request to read the pressure (current in the antena is induced by electromagnetic field). This requires that your phone is quite close to the device.

 @woofer2609: analog gauges are nice but they don't handle both high and low psi applications as well a digital. I had a great accugage analog gauge but it only went to 60psi, which made it useless for the road bike... replaced it with a Topeak D2 and it'll go to like 150psi without any issues, uses a CR2032 battery that I only need changing about once a year, and works on presta and schrader valves so I can use it for my truck, motorcycle, road bike, mountain bike, and pretty much any other tire I need to check.

I’ve been using the pinch method for a good 25 years now and it seems to be fine. But maybe I’d be way faster if I got exact about my air pressure?

 www.sks-germany.com/en/products/airspy-sv ~70EUR here in Europe for a set of 2 so less than those tubes.

 Top tip young players. For about $30 you can get 4 schrader valve caps that have built in pressure sensors. Comes with a little display you could put on your handlebars too if that's your thing.
In all honesty though, if you get a puncture, you'll know about it and shouldn't need an app to tell you. Keep electronics off your bike, pedal with your legs and shift with cables.

 Let's see what I can invent this morning? ....... Found! a sensor to connect the panties to the smartphone that tells me when it is convenient to change them. One app with three colors, green, yellow and red.
Well, it goes without saying that it is advisable to get to red only in extreme cases .......

 These are the worst tubes on the market. Period. The point of a tube is to be able to put air in them and ride. These are lighter, but who cares about weight when at the first corner, they pinch flat on you. You might as well make a tube out of leaves and tire patch cement at the trailside. That will hold air longer.

 So your phone can now tell you what you already know when they inevitably split at their bonding seams in a matter of hours? I soooo wanted these tubes to work cuz the size and weight as a backup *could be unbeatable. 6 tubes and a lot of money down the drain later and I gave up, sorry Tubolito!

 I like the idea of new things, the issue can be getting traction enough to get the price down to a level people find acceptable as a throw away item. I would guess the PCBA cost could be down as low as $2 in the mass manufacturing arena without cutting corners.

 Why are we improving an obsolete product like a tube? Dont get me wrong, Tubolito is a great thing to carry as a spare tube ( I have one), but since pretty much everybody runs tubeless now, I dont really see the point. The amount of people that actually run a tubolito tube as their primary daily driver inner tube has to be extremely low.. This NFC device should be part of a tubeless stem..that would be more useful for a real world application

 My index, ring finger and thumb are almost as accurate than this gauge. Tubolitos are sick don't get me wrong but they were good enough as it is... This wasn't necessary at all but kudos to tubolito for raising the bar even higher than the unattainable precedent they had already set.

 I use to love the Tubolito tubes before buying it cuz unfortunately they were never really reliable to me, even the company giving me warranty they still a not reliable, now they are on my backpack in case I need a extra tube for a short time,... that's all, sadly for not be really able to use it all the time and punctures always come from no were ...

 Jamming and poking with your thumb works pretty well too I think most of us have a good feel for approximate tire pressure. If your using tubes you have to keep them pretty hard so seems a little pointless.

 Speak for yourself. I am usually very very wrong when I try to guess before putting the gauge on.

 Why didn’t they make a 26“ version for dirtjumpers because they are pretty much the majority of people still riding inner tubes?
Oh wait, they just don’t care how much pressure they have. Just pump as hard as you can

 I'm more interested in the small size of that tube rolled up. I don't need an integrated pressure guage/chip. I'm tubeless but often carry a tube for backup if I can't plug a hole.

 When a company's sole product line is an obsolete technology, then they have to innovate to stay relevant. But somehow I don't think this is it. Now if this tech can be applied to tubeless valves, then you have my attention.

 My recent Tubolitos have been awesome. I tend to smash corners/ g-out / burp tubeless ... so these are by far the best solution I've found for my trail/slope/slalom type of riding. SO thankful that they exist!!!

 We are releasing an NFC valve extension pressure sensor in the next month. It's cheaper than this tube, and it can be reused and used with tubeless wheels. Check us out at www.roverdev.us!

 I have one in my bum bag because it's smaller than a proper one and better than pushing if I put a hole in my tyre that's too much for the sealant. In my Evoc backpack I put normal tubes in

 These are THE WORST tubes you can use. I've gone through three of these in less than 100ft from where I flatted on my tubeless.
  • 4 2
 Seriously, are we still using tubes?

 These have been popular in BMX for a bit because they are almost impossible to pinch flat. I'd be curious how theyd hold up in an MTB though. Very different types of abuse.

 @nsmithbmx:
There’s a lot of great reviews of tubolitos for mtb, it works great, it’s supple and hard to flat, but the bottom line just comes down to are you gonna pay $20 for a tube (and now $50? What if it pops?)
  • 2 0
 @fewnofrwgijn: Yeah I carry one as a spare, IF my tubless fails. But i think that they should have invested this tech into tubless.

 I switched to using a tubolito with cushcore because i got sick of trying to get the tire to seal with small dents in the rim. So far so good - no flats and no noticeable difference in how heavy it feels. I do wish the valve was a bit longer though i was just barely able to get a pump on it.
