How To Fix A Tubeless Puncture On The Trail



Punctures out on the trail are bound to happen sooner or later! It used to be that carrying a spare inner tube and a pump was enough, but with the introduction of tubeless tires, fixing punctures has become a little bit more complicated. Join Anna Cipullo as she shares her hacks to help you fix tubeless punctures while out on the trail, so you don’t have to push your bike back home.

  1. What kind of mini pump is that?

  2. What do you do with a sealant covered cushcore if you need to put in an inner tube? 👀

  3. Clif bars, use the wrapper and a tubolito.

  4. Thanks Anna!! You make it look easy!

  5. I once fixed a puncture in an inner tube with a peice of masking tape. I inflated the tube quickly and the pressure against the tire held it in place. Certainly not a permanent fix but it hot me hone a lot quicker than walking!

  6. One reason to start remounting the tire just to one side of the valve and then continuing around and back to the valve on the other side is that this allows you to use the valve to push the tube further up into the tire and out of harm's way of the tire irons if you need to use them for the last little stretch.

  7. For the side wall I would have just used rubber vulcanizer and a patch on the outside of the tire and been back riding without all the mess and in only about 7 min of ride time wasted

  8. I have a toolset which holds my portable battery air compressor, it fits into the water bottle holder. In my toolset is my tubeless repair kit along with some tyre levers just in case

  9. Great vid. I tried tubeless 5 yrs ago but after 3 punctures that I couldn't fix without using a tube I gave up. I may try again now.

  10. Perfect video, explaining it better than this is impossible. Greetings from Brazil

  11. Funny enough I've never got a puncher on tubeless… about 6 or 7 years….

    Edit: Well the beauty about tubeless is the sealant works when you dont know it, kind of a secret bro you can count on 💚

  12. in my experience tubeless never ever gets punctures and it really easy to set up but i still carry the plugs anyway

  13. This is about the 6th video GMBN have done on how to fix a puncture and at least the second one specific to trail side punctures

  14. Yeah I had experience a major puncture weeks ago, from a nail which I did used the Dart Tool, and to some extent it did worked.

  15. I run tubeless on my MTB of course but I don't understand why there is this misconception about puncturing more easily when running a tube. When you have a tube in the tire you are not more likely to suffer a puncture. Just look a road tire and you can count the number of micro cuts on the tread that if running tubeless would result in a flat. I have a set of MTB tires that suffered a puncture running tubeless and I put tubes in that set and I switch back and forth between tubes and tubeless wheel sets. I feel no difference in riding. Both hold up beautifully.

  16. If you wouldn't ride at 16psi you wouldn't be getting flats all the time. Not really a MTBer if you can't ride tires with 25psi like and adult.
    Tubeless is a waste of time and money, and there is no weight savings so DEAL WITH THAT

  17. My local race promoters often use jersey numbers made of Tyvek™ type material. I keep and repurpose a few those for wrapping spare tubes while they stay stashed away wherever, as a chafe protection. I also use the Tyvek as tire boots. Always know what valve stem length your tube needs to be or carry a valve stem extender, so it sticks out of the rim enough to get purchase on the pump head or CO2 device.

  18. Tubeless must be a dramatic improvement over tubes to endure that mess from sealant! Good lord!
