How To Fix A Tubeless MTB Puncture | Trailside Mountain Bike Repair

(bike runs over dirt) (swoosh noise) – We had a conversation
over a beer last night, we were discussing whether a flat tire is ever a good excuse to end a good ride. Well, today I’m going to show you how to repair your
tubeless tire trail side. So why do tires puncture? If it’s a tubeless system, there’s surely not a tube to pinch. Well, absolutely. What can happen is you’re coming past a really fast section like this, you can un-weight the bike and then as you weight it again, something such as that could just tear the carcass or the tread of the tire. So well the air seal is broken. So first thing’s first, we need to see if the
sealant can do it’s job. Sealant is there to fill in those small holes and lacerations. And it’s probably doing it all the time without you even realizing. So we need to give it the best chance. So if you’ve got a small hole and maybe it’s just spurting out a little, just rotate it to the bottom to make sure some sealant
can kind of cover it and hopefully seal it. If not, this is how you
repair it with a plug. So what do we do? Well, the first thing we do
is we thank our lucky stars that it’s not raining. Thank you lucky stars. And then we tend to the tire itself. If it is going to be a plug job, then you need to determine how big of a hole is for the size of the plug. They come in two sizes for different size holes, small or large. Now the tool itself is
actually a reaming tool. What that means is, think of
it a bit like a workshop file, it can basically rough
up the edges of the hole, and this is really useful
for your bigger ones. One on this one, though, is only small, so I’m just going to use a small plug. We’re going to install the plug into the tool the bar at midpoint, then very simply, we’re just going to
drive it into the hole. You want to be careful
here you’re not going to tear or snag your rim tape. So just be sensible. Once it’s in, we do a
few twists, out it comes, and then you cut the
excess off with a knife and job’s a goodun. Now if you’re quick, you don’t
really lose much air at all. But of course, you
might need to top it up, so have a CO2 or pump on hand. And it really is as simple as that. Before you know it, you’re back on the chairlift for another run. Now as always guys,
don’t forget to follow us on whichever social media you like be that Instagram, Facebook,
or of course YouTube, and get in the comments. How do you solve your ride turning into an absolute nightmare? Do you let punctures stand
in the way of a good time? Thanks for watching guys, and we’ll see you next time.

  1. "Go tubeless you'll never get a puncture!" -> How to fix tubeless puncture 😀 You got the love the tubeless fad sheeps…. 😀

  2. Weird time to release this video shortly after the launch of the much superior Stan's dart tool. Kinda makes this video immediately outdated.

  3. I have only recently converted to tubeless. Thankfully I haven't had a puncture yet. For the inevitable puncture the sealant can't handle. The tubeless plugs I carry are Dynaplug. Their plug fuses to the tyre. It has a brass tip so the tyre doesn't need reaming. The plug have a brass tip. So that is why you don't need to ream the tyre. The repair is permanent. The plugs can be used in any tubeless tyre. It has been independently tested in a car tyre 3.5" 16D nail (what ever that is). The tyer was then tested at speeds up to 150 km/h (90mph).

  4. I bet there were some conversations over a beer last night that were waaayyy more fun, if less useful, than tubeless worm stabs…i've seen ur post AP round up interviews!!!??

  5. Ridden tubeless for years, carry worms, never (yet..dont tempt fate) had to do this…so v good to see it done. Cheers H?

  6. We were hauling our bikes up a steep mountain when my wife chucked her bike 5 meters because she swore that hissing sound was an angry snake.? She still blames snakes for the puncture.

  7. Glad for this. I bought a tubeless repair kit and I was like, ‘okay. Now what the fuck do I do with this if I get a flat?! ?’.

  8. Tried 3 tubeless sealants, never again, back to tubes, no nonsense solution. No extortionately priced plugs required either.
    How to cause tubes and patches to make a big comeback? Just put a ridiculous pricetag on them and job done. Works every time in recent MTB "breakthroughs"

  9. I had a bad puncture once on an old tubeless. It was skirting out real fast so I put my finger on it, found whatever rough organic matter I could find on the ground, then pressed it into/against the hole and held it there again for a few minutes, hole side down so more sealant went into the hole. And it held! Put a bit more air in, waited another minute and continued on my ride. Then went to my bike shop and bought a new tire, LOL! You can only trust your luck so far.


    I need more releases on this topic – 4 is not enough.

  11. how often should the sealant be changed? if i only get to ride once a week? unsure how long it would stay liquid, and not become a semi solid rubber mass. i can see the benefits to small holes, or could i just put some in my tube as a middle option?
    thanks you all the great content. and all the inspiration… thanks a lot…

  12. Last weekend. 400 miles from home. GIANT hole in the tire, sealant spraying everywhere. Took two bacon strips and some prayer but it held for the rest of the weekend (still holding, for that matter). Took all of three minutes to get it sorted.

  13. I now always carry Stans Dart tool with two built in plugs. Several old style worms popped out after a few miles but Stans Dart has had over 1000k since November puncture. Still my number one on sealant and plugs…and rims .

  14. I never get flats. And that is because I ride in a fairly controlled fashion. Seriously. If you ride controlled, and you dont thrash like a maniac, there should be no flats with tubeless. Maybe one every three years.
