From someone who has worked on the Spanners at countless World Cup and World championships with the Brilliant Shimano crew Aldo aka Alan Hewitt Martin Clark Rule 58 VeloSport Jon Hargreaves Madison, I can say that was well done, answered a question for someone new to using tubeless road tyres. Thank you.
AWESOMENESS!!! Thanks for helping me patch a rather new tire. I owe you a beer!!!
I prefer the tubeless set up mainly because of the low rolling resistance ( esp. on rough roads ) when you run them on lower pressure ( 4 to 5 bar for a 25 mm tire ) with an increase in grip en comfort. No more pinch flats either.
Continental GP 5000 TL install with a simple pump. Great video to share knowledge when a puncture occurs.
Normal punctures simply fix themselves with the sealant. Larger ones can be plugged with a worm with no need to take off the tyre. Just fitted a pair of Conti 5000 TLs with a standard pump and no issue. 30ml of sealant is plenty in a 25mm tyre and if you put it into the valve with core removed there is no need to be spilling it on yourself! Put the tyre on the opposite side to the valve first and work towards it so that the beads can sit down in the channel and make it easier to complete. I can guess why the final snapping on of the tyre was edited out! No need to carry tubes on a ride; carry one if you insist but you'll probably never need it. (fingers crossed :-) )
MurtxD Great comments. I carry a super light tube as insurance. At 50g it doesn’t need durability to get me back from a ride.
Always be prepared, carry a spare inner tube as well as a tire. It’s best to have one when needed than not have one when needed!
Tire plugs will usually get you home, and even can be a permanent fix. This video shows how to fix the tire from the inside if the plug got you home but didn’t permanently fix the tire.
I just mounted 5000’s on Shimano rims. It was quite a fight. Tight fit. Are you planning to use plugs for flats on a ride? I’m thinking that in my case. After what it took to mount them, I hope to have flat repair on a ride not to include taking the tire off the rim.
You never take a tube to fix a tubeless tire. They weren’t meant for tubes. Once you mount the tire and seat the bead, it should never come unseated until you’re done with the tire. For roadside fixes , carry a plug kit and an inflator. Even if you get a flat, the bead won’t come off the rim. ( providing you don’t ride on it for long). Plug, fill and move on.
I find a lot less clogged valve issues if I angle the stem at apx 45 degs downward while adding or removing air, Just not straight down as some splashing can defy gravity.
I suspect you can avoid the slop when adding sealant by rotating the tire 90 degrees first, then inserting the nozzle aiming down the inside of the tire. Sealant will go in following the tire carcass. Rotate another 90 degrees so the off rim bead is a the top and finish putting the tire on.
Was looking to see how to repair a tubeless tire and saw this sexy gentleman showing how to do it. I think he got my full attention!! And yes, i was successful on the repair.
That wheel tossing intro completely messed with by brain! Pretty cool :)
Nice bit of editing there when fitting that last bit of bead. I'm guessing it was a bugger to fit 🤣. I prefer to put the sealent through the value as it's a cleaner way, but hey each to there own.
I'm really skeptical that superglue will help at all. BTW I'm using MAVIC UST system. Really great and easy to mount and inflated with an ordinary track pump.
Half was thought a deliveroo shift I got a puncture in my tyre that was two large for the sealent.. I handnt got any tubes with me so I nursed the bike to the nearest spar bought some super glue and squirted it on the puncture left it 30s pumped it up and it has been fine for the last 6 months 😂😂😂
Great video
I guess it’s just me or maybe I’m just too old school but tubeless just seems like a huge hassle and super messy. I can’t see what the problem is with a tube. I get one flat every few years and takes me 5 minutes or less to swap the tube or patch it then I just pump up the tire and I’m on my way. No messy sealant no expensive reservoir pumps needed to get the bead to seat or rim tape to worry about replacing. Guess I should try it one day just to see what the hype is about...
I have to admit I completely agree. So much buggering about and gadgets and messy gunk. Having the odd puncture is not the end of the world. A quick patch or spare tube and ten minutes of your life and it’s done. Plus it’s added weight too swilling around a load of slime in your rim. Surprised this has caught on so much.
When you've been into bikes for a few years you realise that there's always some amazing new tech that the industry's pushing. Often it's re-hashed technology that's been around in some form for 50+ years.
Give it 5 years and they'll be phasing out tubeless tyres and talking about how amazing, hassle-free and clean their new inner tube systems are!
In Florida we have sticker weeds that grow in the spring on top of the construction dropping nails all over the road so I get flat's atleast once every two weeks. Tubeless has been amazing but it does suck when you get a puncture too large for the sealent to fix it. Tubeless has never left me stranded through. I've always been able to make it home by just using air cartridges
@@chrisbrewer7777 all my bicycles have tuffy tire liners , not only do they work , I have peace of mind knowing they are doing a job of a sheid between my tire and the tube
For my road bike I am using Conti 4000 25 with new Hed plus rims that are wider than what used to be the norm, I use latex tubes from victoria on these and I can use super low pressure on 25 tires (60-70 psi and I am 195 pounds)! The wheels feel great with this set'up, I use tubeless in a gravel bike and there is no difference in how great both feel. I only had one flat with the latex tubes so I am not changing that any time soon, it must true what they say about latex actually being better than butyl tubes for pinch flats.
After adding sealant etc to a new tire, I would let it sit over night. Just to make sure the air is retained. If the tire is empty by morning, you messed up. Extra precaution.
I do same
30-40ml of sealant is sufficient for a 25c tire
Indeed
Well when you spill 20ml on your hand you have to accommodate the spillage
Just wondering, is tube better to replace without hassle? tubeless tires seems like taking much more time to fix on the road.
This isn’t the process you would do on the road. Just a permanent fix for large punctures. On the road just rotate your tire a few time, the sealant will fix punctures by itself. If you have a large puncture that won’t seal, you can use a cement worm that goes into the hole plugging it. Exactly how you do on cars. While the cement worm can be permanent taking this extra measure provides extra security.
What are some good ways to get the tyre to sit correctly on the rim? I've been trying to get my tyre back on and the safety line in a couple of places is a bit closer to the rim than the rest meaning the tyre wobbles slightly when rotating. I've tried putting tyre lube on the bead, unseating, reseating, deflating, over-inflating and it's still being very stubborn and won't sit evenly.
did you pressure up to the max or even beyond the max until it starts making those sounds?
I am having the same issue. How do we do?
I run only tube and Gator Hardshell. Yesterday was the second expensive tire in a month to get a small slit cut by glass shard. I'm here to research if that is worth patching, and so far it seems not. Will I really trust my life to "special cement" while descending hills at 30 mph in traffic?
I seriously can’t watch channels with their blur the background to death videos, this cinematic video setup crap due to DSLR video needs to go, thank you for not heading down that route. Videos need to be all in focus.
I'm not really a big fan of removing the tubeless tires. Of course with a large puncture it must be done to fix it. The sealant gunk is difficult to clean off and makes it difficult to re-seat the tire. I once managed to blow out the tire, when it had not properly seated upon filling it up. While rolling it in my hands to inspect, the bead slipped off and the air blasted out with most of the fluid. The bang in close quarters sounded like a .22 pistol going off. The tire was ruined and the rim required righting. Something to be aware of.
THATS A LOT OF SEALANT!. 30cc is the recommended amount for a road tire.....60cc at the most. I didnt haveto usecany "high pressure air" when I seated my Schwalbe Ones on a set ofHED ARDENNES=NO PROBLEM.
*So how do I do all this when I'm miles from home in the middle of the street or on a trail?*
switching to Geico insurance can save you 15% or more on car insurance .
or call a friend.
Deborah Custer well I ended up walking over 3 miles home in 100F earlier this week. So mad.
You can bring a patch kit and a spare inner tube with you. Patch the tire up normally and run it "tubed" to get home.
I will use an old inner tube with the super gorilla cement glue (a non toxic as well) cheaper solution.
This is a very helpful idea. Tried your method last week on a tubeless tire that got cut on the thread when I caught the edge of a razor blade left on the road and the sealant wouldn't completely seal. Gorilla tape and a CO2 cartage got me home. Then I used your method and have been riding on the same tire without issue. Simple and cheap, love it.
what glue do you use
You ask me to remove my new tires when I have struggled to put them on? No thanks, next tip
road tubeless is just a way for companies to sell more stuff to you, once everything is added up it costs 2x more to run than w tubes..and, you still need to carry a tube on rides
in 30 yrs of cycling ive only ever had one flat whle out on the road, i must be doing something wrong
I hear you I've ridden for 38 yrs. and a majority on tubulars! I've only had 2 flats in the last 6yrs. This up hear doesn't look fun!
The only thing I'd say you're doing wrong is that you're not cycling enough! :-)
Wow, wish I was as lucky as you! I'm just so tired of roadside punctures, especially on my work commute. I have about 15 flats each year (I'm riding 20.000km anually) and although I've gotten pretty quick in replacing a tube it's just such a nuisance. I just recently converted my gravel commuter to tubeless and thus far I'm happy with it. I only put 1.000km in it in the last two weeks though but haven't had a puncture so far. But yeah - time will tell. There will be a cut that the sealant won't fix for sure and I'm curious how much of a mess this will be on the roadside.
Try cycling in Ireland
You must be cycling somewhere with a government that invests in roads. In Kansas I’m still riding on roads littered with sand and salt from the winter.
I got a puncture and now I can't fix it cos my bike doesn't have an innertube?? I need to change my tyres I'm not clued up on this at all??
At the start you don't mention you need super glue. What sort is it? Just standard super glue?
what tyre boot are you using there?
And I do this on the side of the road how?
With a tube.
No tube. Never. You carry a plug kit. Not a tube. If you get a puncture that sealant won’t seal, don’t break the bead. Just plug and inflate to a reasonable (not high) pressure and ride home. If this isn’t a permanent fix, then use the patch on the inside as this video illustrates. This video is how to fix a tubeless tire before replacing.
@@CCliff0rd What kind of plug kit? Name? I just recently started with tubeless and I'm dreading the first big slice. I hope I didn't jinx myself now! Damn.
twoweeled soto there’s plenty of plug kits out there. I’ve tried quite a few. My favorite is the Sahmurai because it stows easily in the bar ends. It has plugs for 3mm holes . They make different size plugs all the way up to motorcycle tires and car tires. Effetto Mariposa now makes a plug kit that stows in the bar ends with 2 different size plugs. I carry a couple different sizes in my jersey pocket kit. The idea is to ideally plug it without having to break the bead and take the tire off which is where trouble can start. If the tire has been mounted for a while, the bead stretches and you can patch it from the inside but if the bead is stretched , it can be a nightmare trying to reseat the bead. It’s more of a last resort for me.
Also, after plugging it, be careful when you air up the tire if you use co2. This can freeze the latex in the sealant and it will separate from the liquid and become useless. Either use a small pump or if you use co2, make sure your inflated has a variable air knob like lezyne makes so you can air up slowly. Also air it up with the liquid sealant is at the bottom of the tire and the inflator is on top. You don’t have to air up quickly because you didn’t break the bead.
What would happen if I inflate the tyre without sealant? Then let the air out, inject sealant through the valve without core, replace core and pump up?
I'm sure you have figured it out by now, but for anyone else reading: it's a good way to do it. Just make sure that the tire is deflated first, or the valve core may go off flying when removing it.
Can this bike carry 240 lbs?
Dynaplug tubeless tire plug kits are fast and will get you home without removing the tire, ( if you don’t break the bead while riding flat) ;-)
Hi David Ide, I gave up on Dynaplug as they kept failing, coming out thru even a small hole under the pressure etc of riding. Going to use bigger more solid patches like in the video and see if that's better. I have a collection of TL tyres waiting something better than Dynaplug.
@@andrewbackhouse5828 Stan's Darts
i don't agree with this, i don't want to remove a tyre until i need a new tyre or new sealant
if you have a bad puncture the sealant can't handle simple use a rubber worm it will last the life of the tyre, if the puncture is to bad for that to fix then you need a new tyre not a patch
That wasn't messy was it🤣🤣🤣. Take the valve core out its much cleaner .
Through the valve insert the milk
I know this one: put a tube in it ... fixed!
Tubeless is fine when it works but is a right pain in the arse when it doesn't. I notice you didn't replace the old tyre with the stretched bead in your demo. I wonder why? 😉
What tire with the stretched bead ? He repaired the cut in the tire so that it didn't need to be replaced, that was the whole point of the video
@@MrWesman43 You miss the point. If he tried to reinstall the old tire I doubt it would have inflated so easily.
@@tiiimmmaaayyyy3616 He did reinstall the old (repaired) tire - what part of this is difficult for you to understand ;) I have done this exact repair myself on a Schwalbe pro 1 tubeless, and reinstalled my tyres a number of times without issue.
@@MrWesman43 Go to 6.27 and watch him unfold a brand new tyre to install. It's not me having trouble understanding 🤔😉
@@tiiimmmaaayyyy3616 He replaces it because the cut is too big. (he states this) Do you think these tyres cannot be remounted ? Ive done it many times. Do you use tubeless ?
If the tubeless system as we see here was invented first and tubes came second, people would flock to tubes. The disadvantages of tubeless can only be explained by racing. I'm running tubes in 32 mm tubeless ready tires and would rather replace a tube in the street rather than go through the time and mess of repairing a tubeless tire in a shop. BTW, the 32 mm tubeless ready tires came with tubes from the bike manufacturer. They get it.
...You do realise that the manufacturer ships them with tubes so the sealant doesn't get gunked up/block the valve before they're bought? The manufacturer intends you put the sealant in yourself...
@@jdodd1258 I spoke to the local Giant dealer who told me that Giant ships its Mountain Bikes that roll on tubeless tires with sealant. My Road-e bike with 32 mm tubeless ready tires was shipped with tubes. Giant goes both ways.
Lol no way I’m going tubeless! Don’t care about so called rolling resistance advantage, if I get more than one punctured tube a year it’s a bad year for me, this is just the industry looking to find more ways in to your wallet! I’ll stick to my £2 tubes thanks
Exactly.
"This one is a bit stubborn"? Seems like all tubeless tires are stubborn.
twoweeled soto they can be a bit tight some of them but that’s not a bad thing. If you want them to inflate easy , they have to be snug. If they are loose they would lose air when trying to inflate and be impossible to set the bead. The idea here is to set the bead once and leave it set. Never taking the tire off until it’s time to replace. This video shows a last resort on how to patch a large hole from the inside of the tire. But this is only if plugs won’t hold.
I have found tubeless tires to be VERY tight and difficult to install. Always requiring tire levers
...LOL.. super messy , way too much patch glue, forget using super glue
That's why I ride tubulars and if you want . to.put sealant in fine but with all.the steps you got to go through for tubeless it's faster for me to do a tubular
Wear safety glasses. Sealant in eye is bad, bad, bad.
Leaving it overnight to cure? The whole process of fixing a tubeless bicycle tyre is a total pain in the arse and an expensive one. Puncture at 65 km away from home, oh what fun fixing a tubeless tyre.
what?
this video is for repair at home, at the road 65 Km from home you will use a plug and simply re-inflate the tire without taking it off, witch is a lot faster then changing inner tube.
rema tubeless repair kit costs 6€ and can repair up to 3 punctures/tires, you use it to continue riding on your expensive tire after you had a puncture since plug won't last forever.
Please don't comment on things you don't understand.
Both tubes and tubeless have their pros and cons and either system isn't 100% perfect.
or purchase a solid rubber tire from japan and be done with it. . . . 100% no puncture flats ever.
There used to be some British made ones like them. Honeycomb structure.
First to comment... super...
Second heyyy
THATS NOT A TUBELESS
Why isnt it?
Just use a tube!!!!!!!!!
not sturdy at all. made very cheap. avoid this product.
Hmmm, latex tubes in high quality clinchers---> done. Tubeless; marginal gain and large headache. Never forget, it's your TIME that matters: Train or dawdle with tubeless, only you can decide.
sorry but you set it up once and it's not even that long. I had my LBS do it so no time wasted.
Way too technical to fix a flat when on the side of the road in rainy weather. One needs to have a quick method for such circumstances.
Replying to a 2 year old message, but anyway: this isn't how you're going to do it on the road. For a small puncture, the sealant will fix it automatically. If the sealant doesn't cut it, you seal it with a tubeless plug. If it still keeps leaking faster than you can get home, you better have a tube with you, because you likely aren't able to even seat the tire with a transportable-sized pump. Ideally you want to use a booster pump like on the video, or a powerful compressor.
