I needed this video! Thanks Bruh.
ОтветитьWhat's the adhesive type glue you were using? Contact cement?
ОтветитьWhy 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.
Good tricks! I don’t ride tubeless, but I can use these tricks, too.
ОтветитьI’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.
ОтветитьSuch a small hole and the sealant didn't do it's job?
ОтветитьI 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.
ОтветитьVulcanising glue and a bit of an old inner tube are all you need to do this.
ОтветитьAs 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.
ОтветитьWhat 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?😅
ОтветитьI’ve had good luck using automotive radial tire patches. Wax paper between patch and tube overnight, then back to tubeless instead of clamp.
ОтветитьI use Rema Tip Top tt13 repair kit for tubeless tyres. 7€ for 3 patches and glue
ОтветитьNice 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
ОтветитьThanks 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.
ОтветитьA 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.
ОтветитьCheers Alex, any tips for removing stubborn old gunky sealant?
ОтветитьGorilla 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.
ОтветитьBlow 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 😊 🙏
ОтветитьStandard rubber cement and adhesive patches never wants to stick for tire casings long term for me. Will try the Shoe Goo.
ОтветитьChoobless!
ОтветитьSo ... did the tire hold air after that?
ОтветитьHi 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.
Ответитьi lubed tybeles tyre from inside, un and lube eated tyre.
ОтветитьPark 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.
ОтветитьI 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.
ОтветитьThis 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.

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.
ОтветитьJolly good video old boy 🎉
ОтветитьI’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!
ОтветитьТак долго о таком очевидном и элементарном...
ОтветитьI 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 ✌️
ОтветитьMushroom plugs
ОтветитьAny link for buying those patches? Thanks
ОтветитьWhere can I find the list of the products used in this video?
ОтветитьWould you do this on the road? How long would you let the patch sit before riding?
ОтветитьInteresting 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.
ОтветитьWho here has ever managed to get a dismounted tubeless tire that clean??? Raise your hand.
ОтветитьFlex seal tape ftw
ОтветитьThis whole video comes across as somewhat strange when there are standard tubeless patch kits with vulcanizing fluid available for sale. What did I miss?
ОтветитьMy 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.
ОтветитьAs 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.
ОтветитьIn 6000 miles I’ve had one puncture which was too large for sealant to seal. A big construction staple was the perpetrator. I used a “dart” from Stan’s. Other vendors make similar kits. I was surprised you didn’t mention that.
ОтветитьThese videos are just great. You hve just answered every question I had. Great channel. I wish you well,
Ответитьcould you use a blow dryer to heat up the patch and possibly get a better seal? could you also place some gorilla glue over the patch and let that dry up?
ОтветитьHave you used this tire again as a tubeless setup? Is it safe? Will the sealant not leak in the patch?
ОтветитьJust noticed my tyre pressure was half what it normally was on my commute home, so pumped it up and got home and saw some sealant leaking from a hole.
I know if I had innertubes there was no way I could ride home, hopefully it will heal itself now.
Certainly, I can't be the only one with a mind that wanders so much that when I see a puncture get sealed, I look down and think, "Oh, look. My tire is having an orgasm!" I mean when you see spurts of sticky white stuff spray out with each rotation of the tyre . . . . . . . . . 😆
ОтветитьWhat other maintenance videos would you like to see?
