- The bane of any mountain biker, punctures can - at best, delay your ride - and in the worst case, end it. You might be one of the lucky ones and go months, maybe even years at a time without picking up a puncture. Or, you seemingly get one every other ride. If you are in the latter camp, this video is for you.

Hey gmbn tech, love your channel!
#askGMBNtech
Just topped up the sealant on one of my rigs, but don't remember the make i put in in the first place - question: will mixing different sealants trigger it? And are there combinations where we get away with it?!
Anyone know?!
#askGMBNTech
Is "Dynaplug" a safe product to use for fixing punctures? The steel top of the plug will sit on the inside of the tube. Doesn't this damage the inside of the rim on big impacts, even damaging the rimtape?
Doddy always has the best info!
But if you are buying a tire with sidewal armor in a bikeshop how can you see it, you cannot just cut the tire
Some youtubers will have a cut every 3 seconds joining every other word they say, but Doddy can eloquently speak about whatever in the middle of the wilderness and avoid cuts even when changing subject. A good mechanic and a great communicator.
That’s so true mate 🤙🏻
Fast, MTV edit is the blight of modern internet.
yeah, he is so eloquent that he pronounces "inserts" with a z as in inzerts. drives me up the wall I gave up on the video, must be my minor ocd.
@@funkycoldm3dina isn't "inzerts" the conventional way to speak? Im Brazilian, I learned English by myself just by reading and writing, and the GBMN channels are kinda like my English teachers 😅 actually I'm so used to his accent that I'm starting to find a little awkward the accents from the US
He said he was a journalist before joining gmbn
I for real ride every day on the mountain and getting 1 to 2 punctures a year with inner, no complains about them, easy to repair, cheap to change, and no maintenance at all
(23 psi f and r)
With sealant filled tubes, I found unless you find and remove the thorn (and often they break off at the surface of the tire) it will keep reopening the wound in the tube so even sealant won't fix it.
Funny this, I find the opposite.
I keep the thorns in the tyre as plugs 😁
Have in fact two big ones permanently lodged in there and no pressure loss
After a fixing an inner tube puncture, don't forget to check the tyre for thorns or glass still embedded in it that will re-puncture your tube
I run Tannus Armour and I am liking it
I ordered some from the UK site after reading through these comments but but sceptical as I’ve asked a few questions and no ones got back to me. Has anyone had any issues with the Tannus Armour uk site?
I solved the punctures with the internal foam armour + an inner tube with sealant. I don't even have to check the pressure for weeks a time. Before I managed to puncture the tubeless setup two times.
I've been using inner tube sealant in a tubeless setup, works just fine.
Tubeless, Cush Core, and 120 tpi tires is my preferred setup. Stands Dart as a backup. Even if all those systems fail, I can still get home without destroying my rims due to the Cush Cores.
I use tyre liners and in some instances I use 2 plys of liners to add extra protection. Works like a charm.
Tnx for your advice ❤
It's all just too much faff, just get a pair of Tannus armour inserts like I have ;)
This armour solved it for me for good!
With the weight penalty and the sealant slushing around noticeably in mind, i went for more resilient yet still light *PU tubes* for my fatbike - with 4" lightweight JumboJims and a _LOT_ of bare rubber showing in between knobs i haven't had a single puncture in 12 months now!
Bro whuch tube fid you used my fat tyre size is 20×4 which tube will be best
@@rahimuhammad1837 Got me a pair of revoloop fat 26x4". Can't say wich one is "best" since i have nothing to compare to - it's the only one i've ever used. Works perfectly fine! Not a single flat ever since. 🤞🏻🍀
I don’t now why but for the year that I’ve been riding I haven’t gotten a single puncture
Oh dear, now you've done it :)
@@caramba10 touch wood
I got 3 yesterday 😥
You’ve said it now 🤣
Because tires and tubes have come a long way
If you are running tubes, instead of inserting sealant into the tubes (which is not a bad thing in any way), try tyre liners instead. I haven't had a puncture in 10 years and ride in South Africa where thorns are all over the place.
What do you use? I've read those separate inserts cut tubes with their edges
Tire liner can be made from used tires, seat belts, leather belts....
This guy know, your exactley correct. Lots of money be made in tubless though, its cool hahahhaha. Good liner all you need. A barrier between tube and tire. So easy
I’ve found that filling my tires with custard not only prevents punctures, but also makes a lovely little squelching noise as you blast down the trails 🥳
@Michael H. Ambrosia, never Birds 🤣
Great information to know. Thanks 4 sharing. Cheers !!😎😎😎😎
Tubes for life!!! Don't need the mess and headache of tubless along with low pressure slugish feel. My friends with tubless have way more issues then I've ever had with tubes.
Very informative video.. thanks a lot
Hey Doddy,
awesome content lately. GMBN Tech honestly the best channel on TH-cam about MTB
related stuff. Big shout out for that.
Watching your latest video about preventing punctures I've got set back to my situation lately. I've had a massive problem with pinch punctures in the past and haven't still been fully able to solve the issue. Thicker carcass, switching to tubeless, playing with tire pressure...
I was wondering if a cush core or a tire insert could help.
Could you make a specific video about choosing the right one for Enduro, XC?
I use tube's with a Kevlar 'style strip inside the tire and haven't a puncture since...that's 2 years now....Highly recommended
That is the industry standard for the last 10-15 years and does well enough on road.
Great video and info thanks.
Cool imma try to find the tape thing because I think my rims are compatible with tubeless setup so yeah thanks for the tips! 😎
I road bikes in Stockton Cali and wrenched there as well. Road my bike from the (midwest) back and forth to work. I must of had 10 flats just from the debres on the road in Stockton. But have no fear, californians know a secret. My lead tech tipped me off to rhino dillos, I literally have never had a flat sence. Ever.
My last big discovery was the Specialized rim tape which is just a glue less loop with a hole for the valve that you span around the rim like cushcore. This worked so perfectly smooth for me...
Inner tube 'slime' never worked for me and my mate. Just pissed everywhere and made changing the tube a pain! Tubeless never appealed to me despite so many folk saying its best thing since sliced bread! Experience with sealer in tubes put me off plus the heath robinson type of sealing with tape which just doesn't feel right. Now waiting my Tannus Armour insert for tubed tyres. Theory is great and 95% reviews are glowing. Lets see!
I switched to maxxis double down in rear , make sure its topped off with sealant and don't even worry about flats anymore.
#AskGMBNTech Loving the format of these videos - I know for some of the old time subscribers you might be going over the same content, but it is worth repeating with the latest kit on hand. From a purely educational point of view, I would love to see some suspension set-up videos with the smaller brands - Ohlins, DVO etc. How they differ from the big two? Same with some of the more cheeky bits of kit out there - like the Box One Prime 9 X-Wide, Magura brakes or dare I say some mix-matches of components (knowing that brands might not be too supportive of that content). Solid work.
Very helpful is the GMB Tech channel
Rims sadly arent compatable with tubeless so i bought tubes with schrader valves and bought tubeless sealant
So far it have proven effective against sand spurs and more effective and lighter than liners to boot!
I set up my non tubeless rims tubeless and it works flawlessly! Just needed some tubeless rimtape and used the compressor at the local gas station.
Informative as always, thank you! 👌
Side note: Which jacket are you wearing there? Looks good but I struggle finding it at Gore...
I have sealant in my innertubes, but for 2.8 tyres, they're pretty heavy tho. I need new bike:) Cool video Doddy, cheers🍻
Let me guess without watching: go tubless? ;)
I'm thinking about using tire inserts for my tubeless setup. I was thinking that maybe inserts can't fit tight enough onto the tires tread area with a tubeless setup and that tubes are needed for the inserts to stay onto the inner tread wall of the tire. It's good to know Doddy uses inserts for his wheels.
Im still running with inner tubes and have used the inner tube sealant shown in this vid.... Only one thing about that stuff is ensure that you clean around where the inner tube valve screws in... If for what ever reason you need to remove valve this stuff can and has on mine make it harder to remove other than that awesome stuff!
I'm not sold on tubeless. I plan on getting a pair of Schwalbe Marathon Plus (will start with the rear wheel first).
I was so skeptical of tubeless. Luckily for me you are praising the tubeless setup so much that I decided to try it. And I love it! It's tricky the first time, but it's totally worth the effort. And don't cheap out on tires, they are quite literally what keeps you rolling on a bike. It's the most important component of all of them.
Great to hear! 🔧
Tannus armour tire inserts, I haven't had a puncture in over 6 months. Best investment I have made on my bike.
Yeah nah tubeless isn't for everyone
What about a proper puncture protection like a Freeride tube and dh or enduro spec tyre
4 yrs no punny 😁
I tried tubeless it ripped tyre off about 3 times valves and sealant in the bin
Had a crash last week because tubeless tyre burped off the rim of my front wheel. Not happy.
Tire liners + inner tubes can go a long way. I'm not racing most of the time, so any detriment to tire suppleness or rolling resistance is irrelevant and can be compensated with better riding skill and awareness of limits.
Hmm, I run 60psi and tubes with slime in there.
The only time I had a puncture was when a big rusty staple made 2 big holes, it actually went down but so slowly that I ride 5 miles home before pulling out the staples at which point the tyre did start going down faster but I pumped it up more and left the holes at the bottom where more sealant was and it fixed itself, still ok a year later.
Obviously 60psi is not very subtle to ride on lol but I do have full suspension and a gel seat and I'm no serious downhill rider.
Hopped onto a curb yesterday with a dh casing and got a slit in the center of my tire. No sharp edge. With tire insert. Bacon strip fixed it in no time but it was unexpected.
Thank you much for the suggestions. It’s so annoying to ride so far then you realize that the tires are deflated .
Jackets dope
Thank yo Mr Dodd.....tubeless is the best ! I am going to get the Vittoria inserts eventually , as races could be happening over here . We are getting possible scenarios in ways they have to start etc... be safe !
Personally I've had nothing but problems with tubeless. Ran them with loads of sealent, decent tyres but would continually get punctures and they wouldnt seal. Ended up sticking tubes back in as couldn't afford to waste tyre with plenty tread left on them
I got nearly 20 years out of a standard size green tube stretched out in a Gazzaloddi 3.0 tyre.
When I removed it (not due to a flat) the tybe had deformed round the valve like an hourglass (yet filled the gap so there was never a hollow.
I got a year out of my Giant Faith before last weekend when I dropped a skate park 3x1' step... 3rd time unlucky...
then 3 days later, down a 2x20step in town I made it home hut flat the next morning....
Avoiding sharp edge concrete steps may be an idea.
q8D
No puncture for over 12k km now, using orange seal + Victoria Barzo 🤣
Soon as I went tubeless I got my first flat after landing awkwardly on a small jump. Made me fall off the bike. Liquid everywhere. Sucks changing a flat on dirt trail with all that sticky liquid everywhere on the tire and tube.
#askGMBNTech
I am very interested in a test of the Schwalbe Aerothan inner tube. It should work very well and I would like to know what Doddy has to say about it.
Cheers
Try Tannus no flat tires ... perfect 👌😜✌️
Could you put a tube in a tubeless tire for double protection?
Never had a problem with punctures on inner tubes. Ain’t broke, don’t need fixing...
#AskGMBNTech - I bought a beginner MTB (Cannondale Trail 7) earlier this year, not knowing whether or not I would like mountain biking. But now I would like a mountain bike that is a bit more capable. Should I upgrade my bike or sell and buy a new one?
Upgrading will teach me how to fix it myself, but probably cost more than buying a new bike. What would you recommend? Off cause I will watch and rewatch any relevant GMBT Tech videos
sg carcass, inlays, cush core for example
Since I moved to tubeless I have had not a single puncture. I became a master of repairing tubes because I was always repairing them. I’m sure it will happen but I’m talking about years not weeks like it would be in the tube days
I use cheap threaded tyres (kenda kinetics) with inner tube...i got only one slow puncture last year. Lol
#askGMBNTech
Whats your opinion on the cube stereo 170 race, thats the kind of bike I was looking for and I think you get really nice specs for the price.
i havent gotten a puncture in 2 years, even with low rather pressure (1,5/1,7 bar), hitting sharp stuff with accelerated 90kg... and i don't choose lines, lines choose me. i guess maxxis DD casing does the trick. i think it's worth the extra kg of rotating mass. you get used to it plus i have almost no damage on my rims. i will never go back to trail casing.
i run DH casing tyres and innertubes and run them at a hard PSI, im scared of geting punctures and i never get them. Im wanting to go tubeless but all my mates keep getting punctures so im struggling to see the benefits. Any advice would be helpful
4 years running tubeless on a non tubeless ready rim. No puncture since then, but need to check my tire pressure more often than with butyl inner tubes. And getting so much more grip as I can run 0.7 to 0.8 bar less than before. Definitly not going back.
I think at times we put a bit too much emphasis on weight. Yes, if you are racing seriously XC. I understand but for the 99% of us... we just don’t notice the difference of a few grams.
What about anti flat for tubes??
#askgmbntechs
I am looking to buy an enduro bike and in my top list is the YT Capra (others are PROPAIN Tyee, ROSE RootMiller 2 and CANYON Spectral 6).
I’ve been told seems like a new Capra is coming soon.
Any confirmation on this info, when should it be and what may change in respect to actual 2021 model ?
Yann
Ive ran both tubless and a tube in my wheels and my opinion running a tube is cheaper then running a tubless set up . I dont mind the weight of the of the tubes .
@AskGMBNTechs I tried setting my bike up as tubeless I had followed everything correctly and my rear tire is still not sealing why might that be?
#AskGMBNTechs this is helpful for me
I haven’t had a puncture since I went tubeless.I run 18 psi front and 21psi rear
What is the toughest 2.5 26 inch tire?
#AskGMBNTechs
I just bought a Mavic EX630 27.5 hookless rim for my bike. I have Continental Mountain King 2.4s on both wheels. Will these tires work on this rim? I've been doing a lot of research on it, and can't find anything definitive.
#AskGMBNTEch what was that handlebar cap end which had tubeless repair kit in it?
Gorilla handy roll is soooo much better than stans no tube crispy tape.
How so?
@@mtbboy1993 cheaper, stickier and molds into wheels easier.
@@tonyparkin3379 ok, good to know. another info about tapes you can share?, I currently use Gorilal tape.
#AskGMBNTech - Doddy can you fix dents in alloy frames?
Currently waiting for my current tires wearing out so i can go tubeless with the next one. I get spikes every other ride, it's really annoying :D
If you run tubeless tires. ( I have new bike, reading all kinds pros n cons. but if running tubeless and have flat out on trail, how the hell do you get the bead to snap back on if it goes completley flat an you have to plug it? Or do you just throw a tube in it? Think im gonna keep running tubes with Tannus armour, Idont care about extra weight that much. )
I have riding buddy who has recently started to get a lot of "snake bite" punctures. The tires on his bike a few years old (~3 years) and the tread is fairly worn down. He runs his tubes at 25-30 psi. Could the age and condition of his tires be causing the punctures.
Can I use a racework cassette with a sram derailleur
@GMBNTech
Did you quit the ASKGmbnTech sereis on Monday?
Bad lines, good times
Doddy, offtopic. Does your helmet and the visor have same colour?. Mine, the visor is slightly brownish the helmet is grey. Thank you
To anyone riding tubes still what you can do is put about 1-2 layers of gorilla tape or any tape to cover the top inside of the tyre so you have extra room between the tyre and tube then find an old inner tube in your size and cut it through the middle of the tube itself cut the valve out and put your new tube into the old tube and make sure that the old tube is lined up right which can give you sidewall protection not much but just enough, put everything back together pump it up to your pressure then hopefully you’ll never get a puncture from something in the tyre
Running Stan's wheels still works the only punctures are goat head thorns, and rare cases a nail.
"now have a good look around your rim!“ 😏
#AskGMBNTech Why is the Zeb (38mm stanchions) thicker than the Boxxer (35mm stanchions)? I have been confused about this for a while. Love the show!
Because 35mm is smaller than 38mm?
Just kidding. Most likely they have to go smaller to do the much longer tubes and they end up stiffer despite the smaller size. But that is a good question. Hhhhmmm...
Maybe because the zeb is a newer Model and heavier? Wouldn't be suprised if the next generation of boxxer will be 38mm or even 40mm
@@michael_the_chef thats what i was thinking
I guess airless tyres are out of the question. Currently, I don't believe they make anything larger than a 40mm and they certainly don't have the nubbies. The ride quality is not forgiving enough, but I am hopeful that in the future things will change. In the meantime it's tubless with inserts.
Since going tubeless I haven’t had a puncture. I just pump up my tyre sometimes.
I haven't gotten a puncture in almost 5 years... I use 2 inner tubes in each wheel hahahaha.
I don't really care about weight that much, and punctures suuuck so to me, eliminating punctures completely justifies it. (still susceptible to pinch flats if you're not careful tho)
I gut a used tube and place it between the new one (that holds the air pressure) and the tire, effectively having a tube with double the thickness.
FIY: I ride a cross country hard tail on some gnarly-ish stuff sometimes, if that's important .
I still don't know why we haven't serious Airless Tires on market.
#AskGMBNTechs I can't reach my forks full travel i have a marzocchi bomber 66 rcv ( open bath, with a spring unside and air preload)
why dont they make a foam that is put into the innertube to whatever pressure you want and after a few minutes it sets, but not hard, just to the type pressure.
Any 100% options for fat tyres 20 inch x 4 inch for my Alpine Explorer ETRIKE from Alpine Bikes? Solid Rubber tires or Solid Inner Tubes, etc. I have only had it for 2 weeks and already have had 3 punctures and had a mechanic put tire slime in but nothing works for more than 24 hours before tires are flat again. Anyone know of anybody in Fife, Scotland that can sort the tires for me. I'm desperate for help.
Decent sealant... that is *not* mucoff! I’ve got mucoff valves... awesome, mucoff sprays, but their sealant has failed on me where as stuff like stans has not. Maybe it’s just me, but I’ve not had much luck with their sealant
Can I use standard wd-40 for lubing everything on the bike? Including the bearings?
This is a serious question!
Nope. Wd-40 makes specific bike lubricants, or check your local shop.
Aside from weight, what are other disadvantage using solid tyre?
Rolling resistance, as it takes more force to deform the tire
Can’t bend to conform to terrain; poor traction.
Muc off Muc off Muc off,other products are available lol 😆
They are sponsored by Muc-Off. They have to mention it if they have a product for the video.
I have got my last flat about 3 years ago.
I just run maxxis double down/dh or michelin dh casing tyres. (assegai/dhf/dhr2/hr2/shorty/dissector/dh22/dh34)
Stans tubeless sealant or if its super rough the race sealant.
Combined with some decent wheels (for example dt swiss e1700/ex1700/ex511).
With the right tyre pressure for me: Front: 22-25 Psi, Rear: 23-26.
Also the suspension has to be dialed. (helps with line choice and dampens the hardest hits.
All mentioned points above had eliminated flats for me so far.
I’m still confused about those snakebite punctures?
Anyone ordered off the UK tannus armour website? Ordered some after reading the comments here and asked some question and have had no response, thinking now I won’t receive anything.
#AskGMBNTech
With bikes being more capable, will riding trails progressively get more easy and less interesting as they improve ?
Is their a point at which better bikes defeat the challenge of riding?
As bikes get more extreme, so do trails. Think RedBull rampage.
Inner tube + Tannus Armour = no flats
Also doesnt really work. Tannus Armour is reducing thickness after a few rides and is flat like pancake maximum 2mm thickness
