How to Fix a Cycle Puncture Permanently
Vložit
- čas přidán 23. 04. 2023
- Vulcanizing puncture patches can be used to permanently fix punctures in bicycle tubes. The kit I'm using here is the Park Tool VP-1, and there are several in the market.
1) Pick a patch of the right size - you may have more than one hole in the case of a snakebite puncture, for instance
2) Sandpaper around the hole to roughen surface
3) Apply vulcanizing fluid around the hole. Ensure you cover an area larger than the patch as you don't want the patch to peel at the edges
4) Peel the silver backing off the patch and apply the patch over the hole, pressing firmly all over, especially around the edges
5) Wait for a couple of minutes, examine to see the edges aren't coming apart. You're done!
You can inflate just a bit outside the tyre to examine it, but do not inflate much more than that when outside the tyre.
With this type of patch, the patch chemically bonds with the tube, essentially becoming "one with" the tube - you can even patch over a patch.
Please note that vulcanizing patches are different from pre-glued patches. They work well too, but will not be as everlasting as the vulcanizing variant.

It takes 12 hours(overnight) to fully cure. Only inflate tube to 60% after this "emergency" repair, just enough to reach home. A good practice is to carry an extra tube. This way you can repair the damaged tube at home later.
Interesting! I must say I've never repaired a flat like this on the road - always replaced and done at home. Does make sense that the reaction would not complete instantly.
No it's instant as long as you give the glue enough time to cure before applying the patch
Great instructions
I always leave the clear plastic sheet on, pulling it off always seem to pull the patch loose
I leave it on as well - it does protect the edges of the patch, especially when you've just applied it. In my experience though, they've always come off by themselves inside the tyre. So when I remove the tube the next time, I never see the clear film still attached to the patch.
I never thought to leave the plastic on 😂 genius
Perfect 👍
Thanks Ashish!
Make this video on how to open a bicycle tyre; many people will learn the trick and type.
Quick, simple and helpful. Thank you for this!
Nice watch
I bet most people checked to see the watch
What about the puncture on the tire itself? Can you ride on a tire that has a hole in it? As long as the tube has been patched? How come there are so few videos on this topic? Hole in the tire itself?
Good question. There are some videos that talk about it on GCN and GMBN - it would depend on the type of damage. Typically for punctures caused by small thorns or nails, you can just ignore it. However, if the hole is large or the tyre has been slashed, you may need to patch the tyre from the inside using something called a tyre boot. Hope this helps!
