How did you clean all the sealant off so well? Having done this before there's always heaps all over it
@@matchinu He skipped that detail. I use Goo Gone Pro Power, Dawn to clean that up and Acetone to clean it all up down to the rubber.
Thanks Alex, I’ve converted to tubeless on my road bike and loving it. No way I’m using tubes again, although I do still carry one on every ride just in case. 😊
I carry one too. On a recent gravel ride/race, I came across a rider struggling after he flatted (still using tubes!). Lent him my tube... Didn't work. Apparently they can only ride in your bag for so long. 😂
I carry a inner tube too, just in case. But I chose to carry a TPU tube. It is smaller and lighter than a rubber tube.
Issue I have with this - Self adhesive repair patch is specifically designed to patch the tube and depending on brand, most of them work absolutely great. But I would really like to see long term test of sealant on the glue, because I would imagine that in time, sealant can weaken adhesion of the glue and wash the patch off. It was never designed to be coated in sealant. As a get you home - fine. But restoring your damaged tire back?
Also I used tire boot from ParkTool in the past and it works great to save the tire, BUT - adhesion to tire is not easy as tire is not best contact material. Main reason why tire boot works great is that tube is holding it in place and creating constant pressure on the spot. Without a tube and with sealant theoretically spoiling the glue, I can’t see it would work without longer term data.
Exactly!!! For long term I use ordinary patch that you have to glue. Never ever self adhesive patches. With sealant it simply does not work longterm. Ordinary patch with glue lasts for months with no issue!
It _might_ work. The difference I see is that, when you patch an inner tube, air pressure is working to push the patch away from the hole; when you patch the tyre, air pressure is forcing the patch into the hole. However, I too am suspicious of the advice to use a self-adhesive patch. They're great to get you home after a puncture but I don't see any reason to use one when you're sitting at home with a full choice of available materials.
I cut up an old inner tube and made my own patch with rounded edges, glued in place, clamped for 24 hours it looks pretty good to me.
As much as I love the feel of tubeless tyres on a road bike I’ve reverted back to inner tubes. In the last 12 months I’ve gone through 3 tyres all due to sidewall cuts. Patching is hit & miss. They all fail due to higher pressure that you need to run road tyres vs gravel & mtb tyres. If the technology improves I’ll jump back in but for now I’ll run tubeless on my gravel & mount bikes.
Thanks Alex. Appreciate this content. I think in an earlier video you mentioned that we should use more robust inner tube patches and not the instant patches. I have certainly had no issues when using "old school" (heavier weight) inner tube patches and plenty of standard inner tube glue on my tubeless tires. Oh just give it plenty of pressure during curing by puting it under a table leg for 2-4 hours.
I use mushroom plugs. Just ream out the hole where the puncture is, clean the inside of the tyre and glue it in. Means you don't have the worry of the patch pushing out through the unplugged hole or need to botch shoegoo into your hole.
This is the first time I have attempted to repair a tubeless bike tyre. Where I live, we have a lot of road hazards, especially glass. and I ended up with a 3/8 cut in the wear area of my rear tyre. This repair went better than I expected. I used a good grade Upholstery thread, A medium-sized slime patch, Cleaned the area with Isopropyl alcohol, reinstalled the tire on the rim, with a tube installed. and aired up to 30 psi. I will let it sit for 24 Hrs. Thanks for your video, It Helped. Can’t Wait to see how well this repair holds up.

Gorilla tape! I had a little slash from some sharp piece of city street debris that wouldn't seal, even after I jammed a Stans Dart in. Took it home, cleaned the inside as Alex has, just put some gorilla tape over the dart on the inside. 2 years later, it's still going strong even though I've ridden plenty of rooty and rocky trails. Honestly for something like a slice where you don't have a chunk of missing material (and in that case you would want to use a plug), just gorilla taping it seems like the way to go, it'll hold the structure of the tire together better than these smaller patches. Sealant will manage any pinholes.
I’ve had good results using the sidewall of an old racing tire (the part that says Pzero in this video) as a patch. Glue inside to inside using conventional vulcanization cement or contact cement. The hole I patched was about the same size as the one shown here but it was in an ordinary tire (Conti 5k) with a tube. The tire sidewall is thin, flexible and butyl coated, yet remarkably strong and stretch resistant, so it makes an excellent emergency boot, as well as a patch, when glued in from the inside.
What glue do you use?
Thanks for sharing 🙌
@@bennyob22 I used ordinary tube patching, glue. But I found that contact cement worked fine too. Pressure tested to 120 PSI!
Additionally...if you're patching a tire w/ dried sealant on the inside you MUST remove it completely down to fresh, clean tire rubber. I use 3 step process and it works. Goo Gone Pro Power (not Goof Off). Dissolve sealant thoroughly w/ Goo Gone. clean that residue off w/ Dawn. Wipe area well w/ Acetone. you should now have clean rubber ready for scuffing, gluing and patching....or self stick if you like. Happy riding.
Alex you are an Ace at repair! Absolutely stellar! Repair rather than replace. Its better for your purse and the environment. That is all great but a flat on the road with tubeless is a different challenge. I tell tubeless enthusiasts to carry a tube for the on the road repair when their sealant has dried up or the hole is too big for the sealant to meet expectation. I tell long distance riders (tourist), gravel adventurist and mountain bikers who use tubes or go tubeless a side wall cut can be a disaster. There is road repair if you are prepared. Get an old smooth tire, cut a section about 8 inches ( 20 cm ) long. Cut off the bead. Make sure it will reach from one bead to another on your tire. Carry it with your spare tube and tools. When you get a side will cut, put your tire casing between the side wall cut on your tire and inner tube. It may not be ideal but it will let you ride home. When you are out in the boonies your cell phone is not always a backup solution. Walking your bike home is never fun!
I’ve had good luck using automotive radial tire patches. Wax paper between patch and tube overnight, then back to tubeless instead of clamp.
Good vid Alex!
Good tricks! I don’t ride tubeless, but I can use these tricks, too.
I needed this video! Thanks Bruh.
Glad to help!
Standard rubber cement and adhesive patches never wants to stick for tire casings long term for me. Will try the Shoe Goo.
Is this repair just as good for front and rear, or do you recommend using the repaired tyre only on the front?
Does some tires use different inside material?
I couldn’t get the patch and vulcan solution to stick to the Schwalbe PRO one.
Or do you need another patch solution?
What's the adhesive type glue you were using? Contact cement?
I tried this exact method a month ago in a MTB rear tire (maxxis ikon skinwall) 3 times (40 to 60 psi max). 3 different hole size. It didn't work. Well, it worked for about a week, then the sealant starts to degrade the self sticky patch adhesive I guess and start leaking until it gave up and blow up like a proper unsealed puncture. Have to plug then again.
The maxxis ikon are like this pirelli p zero inside. It's like a "threaded semi rubber cloth ish" texture and the patches don't stick too well. I guess that maybe in a all rubber inside tire, it may work fine, and even with a classic inner tube patch kit.
I'm not saying it won't work, that was my experience with this. Maybe for some combination of tire/patch it works just fine.
Tubeless lossen my anxiety on being flat on the middle of nowhere
Thanks you for this vid👍🏻
This procedure will also work on a clincher tire if you are worried that the hole will cause your tube to bulge out of it. If I need a boot, I use what is left of a cotton casing from a 1980's Tub with the tread pulled off. (Back in the 80's, Vittoria Tubs had their treads glued on, so it was easy to pull them off without wrecking the casing....Tubs now have their treads vulcanized on)
In a pinch, dollar bills work well too.
Great tip! Recycling some old tech too 🙌
I will rough up the tire and use contact adhesive on the tire and patch. I also pull any plugs used in temporary repairs.
Jolly good video old boy 🎉
My go to repair lately has just been to add more sealant, spin the wheel and reinflate. I'm continually amazing at the size of hole I can seal with, go figure, sealant. Even for a larger guy like me who needs 90+ psi in his tires.
Totally agree! I'll run at least 60ml in 25mm tyres. And not all sealants are created equally! ✌️
Having a hole that the sealant cannot plug is the worse thing about tubeless tyres in my experience ... until now!
Having to pull the tyre off the rim breaks the seal made by the sealant to keep the system airtight. Most sealants are natural latex and as they dry it becomes a tedious job to clean the rim in readiness for re-installation. The worst sealant for this is Silca's with it's carbon strands that bond to the rim. Awful stuff for road tyres.
If you use a synthetic latex sealant it stays liquid for longer and cleans with good ol' water. Pop the bead, run a hose inside the tyre and you're pretty much done. I use milKit which also has fibres within the sealant and the pressure retention is amazing with Hunt alloy rims (that leak air on the butt joint without sealant) and Hutchinson Fusion5 Performance.
Any link for buying those patches? Thanks
Alex, How do these patches interact with sealant? Will the sealant eventually intrude and defeat the adhesive? Thanks for the knowledge.
Not sure how long those sticky patches would last
@@richardggeorge Yeah. I don't see any reason to use a self-adhesive patch when you're sitting at home with a full choice of tools. Might work better to patch a tyre than a tube, since air pressure is forcing the patch into the hole, here, whereas on a tube, air pressure is pushing the patch off. But just use a traditional patch if time isn't an issue.
Park tool patch I've used bursted through under 5 minutes on the next ride. Something much stronger should be used if you wanna fix it.
i've been struggling with this for the longest time with my tubeless setup, even though its small puncture it doesnt want to seal. can you
guys make a video explanation why this is case for othee sealant/tire combination.
Velox tubeless tyre repair patch kit has all the right adhesive and thick patches you'll need.
I repaired a tubeless tire once with a patch, but I kept imagining the patch coming loose while I was bombing a descent causing a major blowout. I ended up just swapping out the tire. The repaired tire was nearly brand new, but I couldn't justify the cost savings if I got hurt because of a failed repair.
Thanks for the great video. how about a snake bite damage? Does the tire patch still applicable?
I'm hesitant to throw my tire since the thread life is still above 90%
Snake bite on a tubeless tyre?
@@rizzlerforthergyatt Yes, I got into a deep pothole with a hard/edges.I was running/biking at night with 25-30kph speed and only 60-65 psi tire pressure that time.
Sadly my reaction was slow enough not to able to do a small bunny hop thus the bite.
yeah it happened.
I would suggest using Silca sealant, too. This contains carbon fibre hairs which provide a stronger repair from within than standard sealant such as Stan's etc ✌️
How true is that though? I'm running stans and it hasn't been sealing a tiny 1mm hole at 80psi. It will hold 50psi though. I'm thinking about trying silca
I’m using neoprene glue on a slice on my tyre. That witch stuff. Have put it on both inside and outside of a slice and tomorrow will add a bit of old inner tube with rubber cement to the inside for double protection… hopefully save that very expensive tyre!
Vulcanising glue and a bit of an old inner tube are all you need to do this.
For small cuts that did not damage the structure I use Pattex Power Repair. First I clean the cut with brake cleaner, then I fill the gap with glue (the tire is mounted on the rim and slightly inflate it with 45 PSI), then I wrap some tape around the tire and the rim, then I inflate the tire with approx. 90 PSI (so the cut is pressed together). After the next ride I cannot find the cut again.
Where can I get these patches with inner tube material mentioned at 00:01:41? Does it have some kind of structure, so it is possible to repair even larger cuts? Even those Park Tool boot patches don't have any structure, so they are just good for getting home, but not for repairing the tyre, as they will pressed through larger cuts. I still use Continental Supersonic tyres in combination with Vredestein latex inner tubes (dugast latex inner tubes seem to be the same), and as they unfortunately are not longer produced any more, I don't want to throw them away before the tread of the tyre comes through. Any repair kits for tubeless tyres are just the same as the patches for inner tubes - just some rubber, no structure like the tyre has.
Yes, I would like to know what the sheet material is Alex is using
Just use an old inner tube and cut to desired shape. Works a treat I tell thee
Could you do a playlist about tubeless tyres?
As said in the first comment. Vehicle patches and blue tyre cement. Will fix anything because you can get any size patch you need. As long as the patch is substantially larger than the hole or cut, no need for stitching.
#askgcntech - This is great info, but what should I do if I've used a 'bacon strip' to plug the hole while out on the ride? Should I try to extract the plug before patching the inside of the tyre?
Exactly. I’m surprised that wasn’t the start point.
Alex - how did you get home with a puncture that wouldn’t seal if you didn’t plug it?
Dont work on on roadbike u will wear down the bacon 2 quickly and it willl leak.(speaking from experinace)
I tried the shoe goo after Doddy made this video years ago. It did work and last for 3 months on a Vitoria corsa speed. Of course it let go when I was loading my bike to go to a race where I scrambled around like a madman getting a new one mounted. But it does not work on a GP5000 or a Schwaben pro one (previous generation). Whatever about the inside of those tires that is different it won’t stick.
I’ve just glued a gp5000 and patched and it seemed to work. Time will tell but neoprene glue inside and outside seems solid
Thanks Alex (AKA ‘Mr Fancy Pants’ Tech Guru) you converted me to Tubeless and all is well. However I am still pretty new to cycling (2021 - aged 58!) and I hear of tubeless folk also carrying a tube ‘just in case’. Does it matter what tube? Must it be specific to the tyre make and size? Still learning …. Cheers.
As far as a "just get home" function, you can sometimes get away with tubes that are intended for a different size (within limits), but it's definitely better to have a tube designed for your tire size, i.e. 700x25-28c, etc...
I use Rema Tip Top tt13 repair kit for tubeless tyres. 7€ for 3 patches and glue
motorcycle inner tube repair kit more than up to it!
Where can I find the list of the products used in this video?
I had a pair of new tubeless tires die at their second ride by falling down a massive hole on the Tarmac; both got sliced on the sidewall.
I did manage to repair one of them with a slice of bacon, and have ridden it for about 1000km now.
Great video Alex!
Now do it live, on the side of the road/trail using only what you carry in your jersey pockets with no help from your motorized support crew.
☎ “Hello, Ollie?”
Hahaha Doctor Ollie will give it a try 🙌
Hey, Road side repairs are very different to this process, this is for a more permanent fix once at home. We have made other videos for road side fixes.
In a Puncture Repair Kit, ( John Bull for example, or Dunlop, even Halfords when they were an independent shop in Birmingham ) there was a piece of single sided rubber coated canvas. Guess what it was for?
Cheers Alex, any tips for removing stubborn old gunky sealant?
3 step process but it works. Goo Gone Pro Power (not Goof Off). Goo Gone will dissolve the sealant. Clean that up w/ Dawn then wipe area clean w/ Acetone. Now it's ready for the patch process.
Green scouring pads remove the sealant residue nicely. Then an alcohol wipe.
A much easier fix to larger punctures is to add a drop of contact adhesive to the inner side of the (cleaned) puncture. It won't peel off and is 100% reliable. Just make sure it's fully dry before you re-inflate.
My issue with dealing with punctures isn't the complexity of the process, the video was clear. It's the fact that these issues will often arise on a wet day on a ride where you won't be able to let it dry for a day. Also, what if you're commuting, touring or bike packing and need to use the tyre the next day.
Shoes goo on the outside didnt work for me. When it set it just ripped out while riding. Use super glue to stick outside gash together then a puncture repair patch on the inside with rubber goo over it.
Looks like this might work with moderately damaged clinchers as well. Bridge the gap between get you home repairs and hoping to get a few more miles out of them.
Gorilla tape works well. I slashed a tubeless MTB tyre and got another 9mths of use from just using gorilla tape and topping up the sealant
Nice video as usual Alex, but here's my question...if tubeless is all it's cracked up to be why does a puncture that's too small to see not just seal by itself!?. I recently spent 20 minutes at the side of the road waiting for my tubeless tire to seal, but eventually had to put, yes, an inner tube in the thing!. It was a tiny thorn puncture and it wouldn't seal. Now we've all seen the GCN videos where tubeless is put to the test by 6 inch nails and M4 screws - and the tire seals every time!!. So what gives?. Is it just a crap-shoot whether tubeless seals or not, or do some tire/sealant combinations work better than others?. Thanks
Hi Tony, thanks for your comment. Tubeless tyres are not without their downsides too and one of those is that with so many tyre and sealant options and variables such as the volume/age of the sealant used everyone will get a slightly different experience, for better or worse than we see online. The punctured tyre example i used in the video was of a reasonable size and i hoped/expected it to seal at the time, it did, but only enough for me to limp the 15min ride home and wouldn't hold air at high pressure. Just like most products there will be some you have a great experience with and others not so much. In my experience, always carry an inner tube for back up as i have had little successes with roadside plugs. Hope this helps you out. Cheers
In videos where tyres get repeatedly stabbed by larger and larger objects this is a good way to test the sealants theoretical ability to repair a hole. However in these videos none of the tyres have any loading on them. When the tyre is loaded (ie sat on your bike pedalling along) the tyre is constantly being loaded and unloaded in unequal amounts. This causes the tyre casing to flex. This flexing of the casing has the effect of repeatedly reopening the hole the sealant has just fixed, so it tries to fix it again and again and again. This combined with the low volume / high pressure of a road bike tyre means in reality sealants struggle to reliably repair anything larger than a pin prick. I run tubeless in my mountain bike and gravel bike but it will be a very long time before I decided to try road bike tubeless tyres again…
Would you do this on the road? How long would you let the patch sit before riding?
How do you clean the tire with all the sealant to be sure that the adhesive will stick for long?
Same way he showed. It depends on the sealant, but if you're using Stan's, you can wipe it out of the tire pretty easily and remove any dried that's remaining. Then just use alcohol or brake cleaner to remove any residue. I just did this a couple months ago on a tire. Patch is holding perfectly.
I patched up a tubeless tire a few weeks ago and got a special tubeless repair kit for the job. The stuff to glue on the patch was blue and seemingly different from the vulcanising solution you get in normal tube repair kits. Would the vulcanising solution also work on a tire? (especially a tan wall like Alex hab in the video?)
Vulcanising didn’t work for me. What solution and patches did you use?
@@martinarnsten4203 Tip Top TT13 kit with SC-BL solution. Seems to also be a vulcanising solution as far as I found out. My tire was a black, full rubber model though.
@Martin Arnsten what @@chrisridesbicycles said! Use the "Special Blue Cement" Tip Top do kits The blue stuff is the same as what car tyre places use to fit tyre plugs etc, it is diff due to tyre rubber and inner tube rubber are different and "inner tube patch glue" doesn't work well on tyres. So always use the blue stuff on tyres. I also use inner tube feather edge patches on road tyres as they thinner/light, as holes are gen smaller one road tyres. MTB tyres I use the patches that come with the Tiptop kit. I also patch a hole if I notice (lose of pressure/sealant lose) even if the sealant did it job in the end.
@@finelytunedrideftr1932 Thanks for the comprehensive answer. I used the provided patch on my road tire and it is a bit stiff indeed. Another Watt to be pushed by the muscles.
I used a tire patch along with some 3M Spray adhesive that, I'm pretty sure, was just contact cement. It's working great.
Hi Alex, the same thing happened to me so I want to fix my almost-new tyre. Trouble is, I needed to get 2 things I didn’t have, flexible glue and tyre patch material sheet (everything else mentioned I have). I went y to several bike shops but none of them had these things or TBH knew what I was talking about, they just said to buy a new tyre. So can you tell us where to get the patch material and the glue (or even tell us the name of glue). Thanks.
Search for Weldtite Puncture Repair Patch Strip
Use an old inner tube to make your patch. It’s pretty straight forward
After the tire continued to leak, how did you get home?
@3:14 best music ever 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
No tire plugs?
I would have rather watched you deal with the sealant because the visual i get of that messss on the side of the road or even at home keeps me from switching at least with a tube it contains all that sticky stuff for the most part some at the leak site but that's all. Yeah having to deal with that on the side of the road "what a mess"......
Show us that video
Edit: Oh yeah, golly good job mate. keepemcoming
How did you clean the inside of the tire from old sealant? My tires are a mess once I get them off the wheel.
It was probably a brand new tyre they punch the whole in
I just do it with soap. Soap usually needs around ~20sec to break structures apart and after that you wash it away.
@@zedtony8110 it was almost a new tyre, one that i punctured after just a few rides and didn't want to seal up
I've cut up an old innertube, cleaned it up and used that before worked well. What glue would you recommend? I think I used uhu and it lasted 6 months.
@@markh9194 Great suggestion, I had shoe Goo as a bit of an example, but have just used normal vulcanising solution in the past.
So ... did the tire hold air after that?
I wanted to inform you that a lot of Part cleaner sprays are very combustible and this information comes from the Wikipedia (Under Danger) Rubber and some types of plastics are decomposed by brake cleaners by removing binding components. This has the consequence that the rubber will appear unchanged at first; however, it will become brittle, and after a few weeks to months cracks and fractures appear. Years ago, I also used a parts cleaner on a chain and after a month the plating came off completely and the chain rusted. I will never use a parts cleaner on a Bicycle ever again. Save the parts cleaner for your car’s metal parts ok.
i lubed tybeles tyre from inside, un and lube eated tyre.
What if it’s fixed by a plug? Is it worth to pull the plug off and patch it up? If it doesn’t brake don’t touch?😅
Alex sounds a bit under the weather, feel better soon!
This method doesn't work on road tubeless tyres: 1. inner tube patches cannot hold the pressure and will pop out under high pressure. 2. self adheisive patches cannot withstand the corrosion of tubeless sealant and will debond after a while(they only work when sandwiched between inner tube and outer tube). The method that does work is using vehicle tyre patches glued with vulcanizing fluid.
Another proof that road tubeless are bad.
@@diorightRubbish. They are great. Stop being a contrarian for the sake of it.
@@discbrakefan you can keep enjoy this garbage by yourself.
@@dioright or with the thousands of others who ride road tubeless and will never go back. Don’t criticise things you haven’t tried. Makes you sound very dumb.
I have 95% fewer flats with tubeless tires. I will never go back to tubes. That said I have never gotten the tire plugs to work on road tires. The plugs always leak under 80psi.
Interesting that these are on some Pirelli P Zero tyres. I’ve just swapped over to them and have been plagued by punctures. 6 in 250km. Customer services were impressively unhelpful.
Name of that patch? I need some.
I don’t know which patch is that one specifically but if you are in Europe, I personally buy Rose patch kit(costs ~2 euros for 6 of these), it’s thicker and seems to work fine for me.
#askgcn Hi there GCN! I live in China and I would like to ask if an unbranded Chinese hookless carbon rim is safe enough, or should I stay with the hooked version? (And yes I wanna build the wheels myself) The one I'm looking at sells at a not-so-cheap price and does have warranty offered. In Enve's ads, they say that hooks are completely meaningless to tubeless rims, and can be dangerous in some cases. What do you think？
you're gonna build your own wheels?
@@matthiaswarlop2316 or is it called lacing? Just putting the rims, hubs, and spokes together
Surely you'd identify where the leak is by the sealant spewing out from it. 🤔
Add some glitter to your sealant
Так долго о таком очевидном и элементарном...
Why no vulcanizing cement?
Also, for all types of patches, always “stitch” the freshly applied patch by rolling the edge of a coin over it, do it again at 90°.
A knurled edge U.S. quarter (~1” dia) fits in a patch kit, I'm sure every currency has a suitable coin.
Ask the old guys you've been having on, they know.
I tried using vulcanizing cement on the inside of a tyre once -- it didn't stick _at all._
No mention of tyre plugs. Can successfully repair a puncture without the need to remove the tyre.
Tyre plugs are not as reliable. I know one guy that went on a long ride with a tyre plug as the fix and it failed at one point
High pressure in road tyres really doesn’t work well and it’s more of a short term fix. On MTB tyres tho it’s completely different story.
@@intc21 I run 28mm tyres at around 65 psi & have had great success with tyre plugs. But take your point that lower pressures in gravel tyres makes it easier.
I work in a bike shop and do this for living and all my wheels are tubeless, would convert my steering wheel to tubeless if I could but I’ll mark you down as the chosen one 😂😂
@@stevedavis9551 tyre plugs are more "get you home" & temp repair, then when home you can then patch inside of the tyre, in a warm, dry, clean place, with a beverage of you choosing ;-)
Choobless!
Tubeless = no brainer. Far superior to inner tubes. 3 years and no flats. Granted I'm not riding in UK winters LOL.
Who here has ever managed to get a dismounted tubeless tire that clean??? Raise your hand.
This whole video comes across as somewhat strange when there are standard tubeless patch kits with vulcanizing fluid available for sale. What did I miss?
Blow the patch out? Seriously? I‘d like a Tech Vid on how many bars of pressure can be pumped into the tyre before the patch gets blown out please 😊 🙏
Flex seal tape ftw
My repair burst after having my bike in the car. I think it was the heat
Such a small hole and the sealant didn't do it's job?
#askgcntech Hi guys, I would like to buy a new bike and wanted to ask which bike yould you recommend to me. The bikes are as follows: Canyon Aeroad CFR, Cérvelo S5 and Simplon Pride II. What do you think?
I would love to see a roadside repair of tubeless road tyres for when the hole is too much for sealant alone.
I know tyre worms exist but I can't understand how you'd be able to push one through the tyre carcass without either damaging the rim tape breaking the bead meaning that I probably couldn't reinflate the tyre on the roadside.
Knowing my luck I wouldn't be able to remove the tubeless valve to fit an inner tube either.
Thankfully, despite having ridden several thousand miles on tubeless road tyres to date, I've yet to have a puncture that the sealant didn't seal. 🤞🏼
GCN Tech: How To Fix A Tubeless Puncture & Save Your Tyres!
Me: 🤔 Hmm! Can't we use that same technique to address normal tyres with small cuts?
Of course you can! Have you had to repair a tyre on the road side? 👀
This is why road tubeless dont work .Cant even seal a small hole like that ...
Mushroom plugs
Got to say the gmbn video was better, showed you how to stitch the tyre properly
I’d wear a pair of disposable gloves, that disc break cleaner is murder on the skin. But that’s just me.
It's basically acetone isn't it? In which case yes, gloves won't hurt...
One thing I hate the most is punctures lol, I know it is part and parcel of being a cyclist ha.
and how to repair tubular? 😮
just use sealant
carefully cut the stitching enough to expose the tube. patch the tube and resew by hand. Done it, didn't like it. Stopped riding tubulars.
Why not just use an innertube? 😜
Tubeless sound more faff than tubs. Just use an inner tube if you don't have a support crew. Tyres can be repaired with a folded five pound note. Bother, bother, bother :-)
Sure, but 90% of punctures I had with tubes were pinprick size, so I had to undertake the whole process of changing the tube on the roadside, now with tubeless I don’t even notice small punctures, and big ones are easily plugged with tubeless repair kit.
Benefits far outweigh the drawbacks and most issues are usually user related.
I switched to tubeless because pinch flats were getting annoying. It’s not such a big faff as you think, it’s quite easy to setup - the only disadvantage I had is requiring a tyre booster to put it on but the rest is just advantages, especially the ride comfort with lower pressures.
The vast amount of faff is in the house/shed/workshop where its dry and generally warm rather than on the roadside in the pouring rain/freezing cold of the offseason.

I don’t understand the point of this video, that hole was tiny and could be fixed with a plug in 30 seconds?? You wouldn’t need to faff around taking the tyre off and patching it.
The same idea can be applied to larger holes too. Do you repair your tubeless tyres? 🤔
@@gcntech apologies if my reply came across rude, I just re read and that wasn’t my intention. What I meant is that most holes on tubeless tyres will be fixed with a plug. I’m probably wrong, However I’ve never patched after a plug has been put in. Anyway love the content and thanks for the video.
