Not content with just producing the world’s lightest and strongest inner tubes, Tubolito is back with another world first – a smart inner tube. Coincidentally, it’s probably also the world’s most expensive inner tube at nearly $50 a pop. But it does have a pretty neat trick built into its thermoplastic elastomer skin.

NFC Chips

Thanks to a Near Field Communication (NFC) chip implanted near the valve, the Tubolito PSENS is the world’s first smart inner tube that allows you to get near instant tire pressure readings using your smart phone.

The chip is oriented length-wise by the valve, making for a small section of the tube that isn’t flexible, but it’s small enough that you don’t notice it inside the tire.

There is an App for that

Using the free Tubolito app for iOS or Android, you simply place your phone’s camera directly over the valve area and hit ‘Scan’ on the app. If you get the positioning right, about 4-5 seconds later you’ll get a tire pressure readout in both PSI and BAR. If your phone isn’t quite in the right position, you’ll get a ‘Scan Failed’ message, but the app makes it pretty easy to get it right. The Near Field part of NFC means your phone has to be practically right on top of the tire, so you won’t be able to scan it from a distance, but that also means you won’t get interference between the two tires if you’re using two tubes.

The included instructions make it very easy to download the app, and start measuring pressures.

How Accurate?

Compared to an SKS AirChecker digital gauge, I found the Tubolito PSENS to be within 1psi at all pressures, so it seems pretty accurate – at least compared to the average tire pressure gauge.

How much does it Weigh?

Tubolito PSENS smart inner tube actual weight

Since Tubolito starts with one of the lightest inner tubes to begin with, they’re able to build a 29 x 1.8-2.5″ smart tube with a 42mm presta valve that weighs just 85g.

Like some of their other tubes, the PSENS is not compatible with rim brakes and includes a few instructions to follow that are a bit different than your average tube.

Offered in 29 x 1.8-2.5″ or 27.5 x 1.8-2.5″ sizes, both will sell for $49.90. Per tube. Yes, if you wanted to run PSENS front and rear, you’re looking at $100 in tubes alone. But hey, you’ll never have to find a working tire pressure gauge again!

New Patch Kit

Obviously, if you’re spending $50 on a single tube, you’re not going to just throw it away every time you get a flat. Tubolitos promise to offer double the puncture resistance of an average tube, but they’re not infallible.

To make their patches even more durable under high heat, they’ve added a special glue from Rema Tip Top. The patch kits include five small and five large patches, and five alcohol swabs for cleaning. One nice thing about the Tubolito tubes is that the material doesn’t allow tire sealant to stick to them, so if you’re using them as a spare for a tubeless set up, they’re very easy to clean.

Still have some of their self-adhesive patches? Don’t worry, they’re still good to use. Just that the new glued-patches are better at handling higher temperatures. The new Tubo Flix Kit will sell for $4.90.

World’s Lightest Gravel Tube

Tubolito cx/gravel inner tube

These three tubes all fit the same gravel bike tires – though the Tubolito tubes have an even bigger size range.

New for the CX and Gravel world, Tubolito has updated their standard and S-Tubo tubes to fit a wider range of tires. Now compatible with 700c x 30-47mm or 650b x 30-47mm, you get a lot of coverage out of a very light inner tube.

The standard CX/Gravel tube checks in at 60g for the 700c x 30-47mm size with a 42mm presta vavle. These tubes claim to offer better air retention and double the strength of a standard butyl inner tube. Also, this tube is compatible with rim brakes while the S-Tubo below is not. 

Tubolito cx/gravel inner tube s-tube weight

Somehow almost half the weight of the standard tube but with a longer 60mm presta valve (also available with a 42mm valve), the S-Tubo CX/Gravel 700c x 30-47mm tube is so small and light that it is the perfect emergency spare to stick in your pocket for your tubeless set up. Though Tubolito points out that the tubes are durable enough for daily use, and offer lower rolling resistance and better air retention for those who prefer a tubed set up.

Like all Tubolito tubes, the only draw back seems to be the price. The standard Tubo CX/Gravel will run $34.90 per tube, and the S-Tubo CX/Gravel is priced at $37.90 per tube. But as long as you don’t lose it along the way, we’ve found that the tubes are worth the price as an emergency spare since they save so much weight and space in your flat kit.

BMX Tubes too

Finally, Tubolito even has new sizes available for BMX including 20 x 1.5-2.5″ and 22/24 x 1.5-2.5″, both with presta or schrader valves. Each is priced at $34.90 a piece.

    This should stay a concept. It’s interesting tech but adds to the list of frivolous tech the industry puts out to the consumer.

    I’ll stick with my pressure gauge.

  2. Byekr on

    I have tubolito 60mm standard tube front and pre-talc specialized turbo tube rear (only b/c the 80mm stem from tubolito has been out of stock for months) on my MY20 Tarmac SL7. 3,237 miles later: ZERO flats on the tubolito, 4 flats on the turbo tube. Tires used: specialized cotton turbo 26c (981 miles), other half on specialized s-works turbo 26c (2,256 miles)- FWIW I think the tubolito is aweseome!

  3. Ron on

    While I’m not interested in adding some electronic thing to my tubes, I’m glad to see the new size. I’ve run tubolito for, I think, more than 2 years now without any flats, compared to the 1 to 3 flats per year prior. They also seem to lose air at an astonishingly slow rate. So, I love them.

    Would be more interesting frankly with bluetooth. My Lezyne pump also shows me the pressure so, once I am stopped, if I hold my phone to my tire or unscrew the valve top and screw the end of my pump tube onto it, doesn’t really make much of a difference. Except in price. The pump gauge measures any tube and cost me just 20 euros extra. So, as long as I have to stop for a measurement, it does not really take the inconvenience out of pressure measurement.

  5. Petter on

    Will it still work if you just it out of the tube? The potential for a super cut price tire whiz is intriguing seeing as I always ride with a phone.

  6. Dylan Sutton on

    Ditch the tube part and make it something I just stick inside my rim – make it a strain-gauge over a sealed vacuum reference for the low pressure side and it doesn’t need to read a difference between the inside and outside of the tire. Read it every revolution (like an old speed sensor/wheel magnet arrangement), and trigger an alarm on my phone if it starts dropping (configurable fall rate and threshold alarms, predictive-low alerts – any T1 diabetics on here will know what I mean), before it gets low enough for my tire to fold over on hard cornering.

  7. Tim on

    So here’s my question – is the pressure gauge inside the tube directly exposed to the air in the tube, or does it have its own chamber that’s sealed off? Why do i ask? I’m wondering about condensation collecting in the tube and therefore the sensor. And can I cut out the sensor, and stick it to the inside of the tire of my tubeless setup? Then I get almost the same functionality as TyreWiz, for half the price, possibly lighter, without batteries or dongles hanging off my valve stems. if they expose the sensor directly to the air, sealant will likely plug it up pretty quick.

    ahora hazlo al reves, pon el tubolito detras y el specialized delante y con la misma distancia comprueba los pinchazos, siempre es mas facil pinchar en la trasera que soporta mas peso.

  9. Brian B on

    So after a ride the one guy that always complains can scan his tire and say ‘yea I wheel sucked all day but look, I’m done .5psi. That’s why’

  10. nashvillesfred on

    If this were a Tubeless valve that I could check pressure on, that would be great and I would consider buying one, but what consumer that is so [picky] that they would want to check tire pressure in this way would also not be running tubeless?

  11. Rover Development on

    We have an NFC valve extension solution that will soon go to crowdfunding that can be used over and over with different tubes or with tubeless tires. Check us out at for more info.

  12. Dodin on

    so….which one would you use for a 700×43 gravel tire? seems too big for their Cx and too small for their mtb. or am i missing one?

  13. chris on

    Nothing to see here and quite a stupid product at a ridiculously high price – Over 100 bucks for 2 inner tubes! I personally know of much better tech coming down the pipe that’s far more sophisticated, cheaper and works without any inner tube. Sorry guys – Nice try.

  14. MaraudingWalrus on

    Lifetime average I’m probably at 90% rear flats compared to fronts, so I’m not sure that this really indicates tubolito’s extreme puncture resistance. Certainly overwhelmingly rear punctures changed in all my years in shops, as well.

    I also found the “other half” being 2,256 miles compared to the presumed “first half” being 981 miles amusing.

    Is there an annual award for the most pointless “innovation” in cycling? Can I nominate a pressure gauge that you have to bin when you change inner tubes, and only works when the wheel’s not going round?

  16. PAUL COOPER on

    I had nothing but bother with all the tubes i got from these, even out the box 2 of them were burst. 2 others kept going down over 2-4hrs. i have another 2 but still in box and most likely stay there till they rot. A big costly outlay for nothing
