Can You Make an Inner Tube Puncture Proof?
HTML-код
- Опубликовано: 4 июл 2024
- Tubes puncture easily on sharp impacts and tubeless with a foam insert is puncture proof, but has its own set of problems. So I thought, why not combine the two and make an inner tube with a tyre insert inside it, to have a mess free system that still offers impact protection?
Let's find out if it actually works!

Tyre Insert INSIDE an Inner Tube? - I Think I've Found My Favourite Puncture Protection Bike Hack

Crazy! This man might’ve just changed the game. Well done.
My thoughts: "what a smart guy"
AN tube.
Recommendation: If you make a DIY foam insert, don't join it with plastic cable ties. Rather use something that can't do damage from the inside, like string or a hook-and-loop strap. Should be safer :)
Make a video in few days or weeks about your experience with it, how it controls and does it make a difference
Wouldnt bead lock wheels fix tubeless tires? I wouldnt know if anyone creates them but its in interesting idea
@@Marley505 Pinch flats/snake bite punctures
Any update if you got a job offer or prototype out from a big tire brand? I'd buy this in a heartbeat
@@Marley505 I'm sure they would work but they might triple the weight of the wheel.
Another option may be to just pump expanding foam into the tube through the valve. Schraeder valves can be unscrewed to give pretty decent access. You would have to work the foam evenly around the tube before it sets, but it could work as a less invasive option.
The problem is it will stick all over the inside of the tube and won't form a solid rubber shape inside the tube. Also it's full of isocyanates and is actually pretty nasty stuff.
@@wakazuzu The aim of the protector is to stop the tube getting pinched, so provided the tube was lined with enough talcum powder to stop the foam sticking to it (Michelin tubes for example have very little talc in them, so you'd probably have to add more yourself on this brand, but others will have plenty of talc in them already), this could work quite well, if a resilient foam with relatively low expansion was chosen.
The possibility of the expanding foam attacking the rubber chemically would be my biggest concern - and not doing it indoors or anywhere near soft furnishings :-P.
Necessity is the mother of invention ! I hope you've patented it !
One more addition/option is to add 30-60 ml of tubeless sealant inside the tube via the valve. This way, this setup will prevent from a nail or thorn puncture. You mentioned you wanted a mess free set up. This does have sealant involved but inside the tube which should be mess free.
Bro this is a good idea for the bike industry
This is so revolutionary!!! You can use a heated patch..it melts and maybe it will hold better. Excited to experiment on this
Always good to see you have uploaded
This...was...exactly what I needed.
Thank you so much!
Great hack :)
I can imagine that instead of the patches you could also use a piece of old innertube 😊 at least I have no idea where to get these huge patches from haha
I was actually able to buy them at my local bike shop. 3€ a piece - totally worth it :)
look for trailer tire patches at Princess Auto in North America
@@TheUselessTrials Schau mal bei ner Landmaschinenwerkstatt vorbei, das habe ich solche wie den ganz großen von dir als 10er Pack für 15Euro bekommen, die kann man sich dann immer zurecht schneiden. Das mit dem alten Schlauch funktioniert aber auch gut, vor allem wenn man den Schlauch eben ganz durchschneiden und das Foaminlay rein macht. Hast du einfach einen sehr festen Schaumstoff genommen und Panzertape drum gemacht? und mit wie viel Bar fährst du dann auf dem System?
finally a hack video that features an actual hack. i was half expecting some of the well known tips, but no. Gute Sache!!
Have you ever thought about becoming a rocket scientist?? That is actually insane!
It's not insane, it's just too simple for anyone to have thought of that!
I love this DIY project!
Great video! Like the idea!
PS: When is your 180 Barspin video coming? 😉
Insane! Good work!
I have been tearing my tubes appart while trying to keep up with the young guns and their full suspension 29's while shredding on my full rigid 26 at the local trails and found your video. I tried to do this with PVC insullation and 2.125 tubes, but found out they are way too narrow, also since they had sealant, it became very messy very quick. Going to try with some 2.4's and keep updated for any future reference, for anyone else wanting to try this by themselves. But it seems like a very good idea, even better than my other option of going "Ghetto tubeless".
This is brilliant! Does it affect the springiness of the tire? I found that springiness can affect the riding quite a lot, especially the size of sidehops and gaps. Some tires are more "jumpy". Having an insert in the tube probably has some effect on this.
This should totally be a product. Get that patent. Also the foam inserts make putting the tire back on a battle of wills.
Have you ever tried the Tannus Armour? I don't know if exists the right size but it could be an option
the smallest sizes are 20", 24", and 26" . I have the 26" insert on just the back tire of my bike, I've only gotten one flat, the tube slipped and the rim tore off the valve
I had so high hopes with Tannus Armour... Unfortunately after 1-2 months they squished down to a 3mm thin foam liner. (and they weigh 300g) I'm still mad at them lol
BB's comment pretty much sums it up perfectly. I tried a diy insert between rim and tube for a couple of months. Provided some protection, but got compressed into a way too thin layer after a while.
You are so underrated
Love your videos!😍👍
Niiice dude, . Its not every the title bike hack is deserved 🤣
Very good idea! However I use a tire insert (in reality it is a pool noodle cut in half) outside the tube. This "sandwich" has the rim, then the tube, then the insert, then the tire. This insert should be as thick as possible, but should fit inside the tire at the same time. I make the setup, pump my tire at around 2 bars and leave it so overnight. Then I adjust the pressure around 1.8 bar or 1.3 bar, depending on my bike tire size. Needs some experimenting, but I havent had any punctures ever since using it on rocky mtb descends with my hardtails. I even used it in 2,25 inch 26er tire with pressure around 1.8 bar.
I ran a system like that for over a year with some success, but could still get snakebites, because the foam gets compressed into a very thin layer after a while and stops providing protection. Let me know if you've found a type of foam that stays intact.
First off, use smaller sized tubes that fit easily, so you can go thicker.
When first inserting the pool noodle I inflate it to around 2 bars. Overnight it droppes to around 1 bar. Then I never go above 1.7- 1.8 bars. I have tried bunny hopping yesterday and badly messed up a couple, I could even feel rim impacts, but still no punctures. I use 21 internal width rim and 2.35 inch Panaracer Cedric Garcia tire,790 g-s. I have it installed more the a year ago.
I have bought the Tannis Armour, which is the "official version", but I still got snakebites.
So pool noodle. Maybe getting something more rubbery would be a good idea, like NBR mats for pilates. There are thicker versions,like 1.5 cm-s and above. You could cut a long strip and even have two layers: one narrower in the middle and a slightly wider to provide additional sidewall protection.
I give you a billion thumbs up!!!
Did you have any problems re-mounting the inner tube insert on the wheel, or putting the tyre back on?
Went on totally fine!
Add tubeless sealant to make it even more puncture resistant
Foam insert is what? Need to know thanks!!
What tire do you use on your bike
This is genius!!
inner tire tube sliping out from too high pressure and two size bigger tube inside thread with bubble like shape from one point only (slipping) . Any suggestions except ziptie around whole rim with not so wide pieces I got to use it outside in public plus sound of extra hard zipties on human sidewalk
what kind of insert did you use?
Brilliant ! Du bist unser STREETTRIAL MacGYVER !!! 🙌 RESPEKT ! I'll try that !
Video suggestion :
HOW TO BLEED YOUR BRAKES WITH A SWISS ARMY KNIFE AND A BUBBLEGUM 🤪 🤘
Just kidding ! Keep up the good work 😎👊
Could you please do a "How to bunny hop" video please ? ✔️
Is the tire insert homemade? Mine's just a 40mm closed cell backer rod (i was riding tubeless), my rims are.exactly 1in.
Yes, it is!
@@TheUselessTrials thanks! Might as well wrap it with black tape
🙌🏽 NICEEE......Forget the thumbs this is all hands up. WOOP WOOP. Thanks for sharing. I'm currently looking for a bike, WHERE CAN I FIND ONE SEEN IN THIS VIDEO ?
check out tartybikes.co.uk, they have everything trials related
Thank you.
Idk why but I died at 2:05, that sound lmaoo
I run tannus inserts and TPU tubes its the future
So what are you using for the foam insert??
Some durable foam cut into a stip and joined together
This is awesome for sure. I've been using Tannus Armour which is similar, but has the foam wrapping the tube. I'm new to MTB, so I've slammed my rear wheel into rocks and roots heaps of times now with no pinch flats. Would be great to compare the idea of foam inside the tube...that's certainly an awesome testing ground to show that it works!! Well done.
Genius!
OMFG thats almost too little to say!
you could try putting the insert outside the tube
I did! Ran a rear wheel like that for a couple of months with mixed results. The main problem is that the tube compresses the foam into a very thin layer over time.
Inside the tube it seems to work better.
Just like he said and it's a major PITA to get it on the rim together with the tube. It's futile
I just thought about that and the next minute you upload this video. Huh
Brilliant
will try net week will give feedback sfter
The easier way to do this might have been to line the tyre with a foam strip and have the tube between that and the rim. You could take a flat piece of foam and trim it so it also curves around the sidewall.
I ran a system like that for a couple of months. The problem is that the foam gets compressed into a very thin layer over time, leaving close to no protection.
@@TheUselessTrials I imagine the same thing might happen with your insert? Anyway thanks for the video and be sure to provide your long term review.
Bro this has been done for years in childrens bikes and rental bikes.
Sick, but Rey to put tire sealant in the tube
Hi what kind of the brand tube please I want to buy this brand? I'm waiting thanks
I tried to do this with PVC pipe insulation and 2.125 tubes with no success at all. The tube was too narrow, going to try with some 2.4 ones.
@@thetechfromheaven thanks a lot for you
What is a good entry level bike
Extension or Story bikes. Both brand have decent bikes under $800 usd without brakes before ship. Westerners would prefer Story for longer wheel base. If u wan a more bmx feel, Extension would be good.
Sorry, I am not familiar with the foam inserts. I can see in the video that you are pumping up the tube. So I understand that there is air between tube wall and the foam. How does it make it puncture proof?
It makes the tube more cushy so it prevents the rim and the spokes from bottoming out and tearing the tube appart. I find it pretty handy if you want to shred on a full rigid bike.
clever
Trials are so painful to watch as a higher pressure rider xD
Why not just ride with higher pressures? I ride 50 and above psi? and how much weight does it add to your tubes?
Too high a pressure stops your tyre from folding around corners so makes it hard to stay up on the back wheel on sharp edges.
Exactly - more grip to stick to stuff. I run between 2 and 2.5 bar with the insert now. Without it I had to run more than 3, which still doesn't prevent punctures, but compromises grip. The insert adds around 100 g.
What kind of tyre insert is that?
One that I made myself. It's just a strip of durable foam wrapped with tape.
how thick is the foam (diameter)? and what density? and how long? is there a foam insert that could be bought?
you have to patent it man
Why isn’t anyone making Tube-serts™️ yet??
The engineering
Never been a fan of tubeless and the mess plus the chance of ripping the tyre off the rim.
Insulation foam cover and tube inside it in tire. No effort
Dude make a real version trademark and patent and get selling
Fuck that. I’d rather just buy another tube. This looks like too much time and effort just for a bike. Not to mention I’d be spending more, just to do this little DIY, when I could just use the money to simply buy a new tube
woher kommst du bist deutscher des woas i :D wollma mal mitnand biken gehn mach a youtube grüße vom wuppetz😋
Aus Leipzig glaube ich. Hatte ihm mal geschrieben
...or you may just try tannus armour.
All I do is pour tons of tubeless sealent inside my tubes
tube or tubeless sealent?
@@ananthkutuva3748 ? I Inject sealent into tubes that I then put in tyres
This helps for small punctures, but not for a quality snake bite
@@hunterwright386 i asked that because some companies make different sealants for inside tubes and inside tires
Bist du deutscher?
Ja

DUDE, you are bad business. Such product should be eliminated. It would represent less replacements and sales. Fuuucking obsolency and consumistic capitalism.
wtf?
