The proper way to patch a puncture on the base of the valve

Have you ever had a puncture right on the base of the tube’s valve while
being in the middle of nowhere and without having a spare tube? It happened to me before, more times that I can remember. In few of those instances I was lucky and a friend had a tube that I could use, in some others I was the only one with a 28″ bike so I couldn’t use any of my friend’s spare tubes or none of us had any spare tubes. In the last scenarios where I can’t use a spare tube, I desperately tried to patch the impossible puncture in any way possible, wishing that one day I would wise up and stop going for a ride without at least one spare tube in my saddle bag. But that never happened.

So I had to figure out a way to patch those peculiar punctures while on the road. After some trial and error,  I found the best way to fix them. Using that method you either fix it for good or you will have to pump it up every 24 hrs or so. Either way, you ‘ll have a wheel perfectly capable of taking you home.

So here is how:

1
1. The ‘impossible’ puncture. If you don’t have a spare tube you are stuck. Fortunately there is a way..
2
2. This is the important step that makes all the difference: Using a knife, you DRILL (NOT cut out) a small a hole by twisting your knife while applying some pressure.
3a
3. Then carefully push the patch over the valve half way. NOTE: Same principle for car valves
4d
4. While the patch is walf way in, apply some glue underneath it. In cases like this I put more glue than usually on the problematic area.
5
5. Wait 5 mins for the glue to get dry. Then apply firm pressure around the base of the valve and the rest of the patch for 6 mins. See how perfectly the patch sat around the base of the valve using that method.

That’s it! Your tube is ready!

After having the same tube with this patch for few months and traveling around the island of Kefalonia for 4 days, I can say that this is legit!

      You will try it soon for sure! Those damn punctures on the valve are quite common strangely enough :-/

    Ingenious! I have tried and failed to cut u-shaped patches for this. I’m embarrassed I never thought of this, Thank you!

      I am glad you found it useful Ralph. It happens to me all the time, when I am tired and frustrated my brain doesn’t pick the obvious solution 🙂

  3. Oh my! This seems so simple now, of course that would work. I so need to try this out.
