Having ridden tubeless for 3 years now, I can only recommend carrying an old fashioned tyre patch kit. Just glue the rubber patch directly to the inner wall. Don’t abrade the tyre with sandpaper as you would a tube. That works really well and lasts the life of the tyre.
You’ll need to carry a pack of tissues too, obvs.
And some rim tape because simply deflating the tyre can dislodge the valve slightly, and this needs a perfect seal to hold 80psi. The original rim tape will have set itself around the old valve position and therefore will need ripping off and redoing.
And if it’s raining you’ll need to pack a tent because all this is impossible in the wet.

I'll add that you should always check your tires after every ride. Look for signs of sealant on the tire and frame. Using a wet rag on the tire can help show where sealant has been used to clog a recent hole. You will want to top up your sealant more frequently if you're seeing sings of sealant usage (decompress to top up). Use the same sealant as the one that is already inside your tire as not all are compatible. Love your videos GCN--they're so helpful !

I'm getting a bike with a tubeless setup next season, this was a great video to watch ahead of that. A plug repair set will be in my saddlebag!

[GeorgiaLowe-yb]

this is the best video I have ever watched. thank you for saving my cycling life :) so well explained and covers absolutely everything

I'm new to TL tires and found that, after my first puncture, it sealed up nicely and was able to finish my ride with only 5km left.
I was pleasantly surprised and hope I don't get any others. However, with these tips, I'm now more confident in my ability to manage any future punctures.
Thanks for sharing.

Had a puncture a month ago. Used a plug on the side of the road, the repair took less than a minute and still working perfectly.

[jimbrown]

Was having trouble getting my tire back on the rim (even with levers). The bit near the end about centering the tire all the way around did the trick. Thanks.

Is there anything worse? Ehm yeah, that creaking you can't find even after completely rebuilding your bike.

Since shifting to tubeless last year, I have had two punctures that the sealant would not close up. I have used "bacon strips" to seal these up, but last week I had a puncture that the strips just would not seal, and would not allow for a second strip to be inserted. I had to call for help to get transport back home...nothing worse. I have since done two things. First, I bought a Stan's darts system, and it did seal that puncture, so no more "bacon" for me. Second, I bought the new Vittoria Air-Liner Road foam inserts and will be installing them with the new tires I have ordered. Really looking forward to riding with the new setup.

Applying puncture repair cement to the repair strip adds some extra security. Have done it loads of times, always works a treat.

Having a set of clinchers is so much easier. Dealing with the sealant, plugs, co2 comptaiblpiltiy, etc., makes all the things the tubeless systems solves another problem added.

What a useful video! I just took my tubeless outside for only my fourth or fifth ride since I received a tubeless tire and had a flat. I had little to no idea how to repair it until I watched your video. Thank you!

[Brian-pkol]

I’ve converted back to tubes from a tubeless set up. Got standard for the last time. You puncture less, but when it happens it’s more than likely catastrophic. Moved to tuboletos. Bit pricey but so far worth it!

[reidwagner]

I have a tubeless gravel. I always thought I had to use a tube if I flatted. But you showed me the “needle and thread” tool. I’ll carry some disposable gloves and a tire patch as you demonstrated. This was one of the best GCN vids I’ve watched. Thanks!

[nicholaspomponio]

Gr8 job! My daughter and I are triathletes. She has no clue how to fix a flat - I think tubeless is the way to go for her. Thank you!

[rodmarch]

Nice video! There is one problem I've encountered that may be quite rare. Some tires do not seat well on some rims until you reach higher pressures than you want for riding, particularly true when running a tube after a puncture. If the tire hasn't fully seated on the rim, the tire may wobble side to side or seem to have a lump in it. You may even think the tire is defective. Increasing the tire pressure to get it fully seated and then lowering it back to your riding pressure can solve this. I had this problem with Schwalbe G-One Allrounds (gravel tire) on Roval CLX rims; had to get them up to 105-110 psi before they fully seated, then lowered back to about 50 psi for riding.

[harlowcyclingpage]

My experience is on my review blog, best advice is if you run into trouble is clean up any sealant before putting the bike away for the night, it took me two, days to clean a gravel tire up good enough to reuse. Next time I had a problem I simply cleaned the tyre and wheel, 20 minutes is all it took, there is a couple of videos on my review blog of the Agro I had with cleaning, great video GCN, keep them coming, clear and informative, thanks

Just bought a new bike with tubeless so found this interesting ; will definitely never ride without my phone in the back pocket, lol.

[adamrice]

Having just got a new bike with tubeless setup already installed, I had toyed with the idea of switching back to what I know best (tubes), as I am a little daunted, but this does help!
