Would you use a repaired tube?

Not aimed at you Skol.

WRONG! Swap for a pre-repaired tube at the roadside then fix the punctured one later. There is no limit to the number of patches that can be safely applied to a tube. The end of life is reached when a catastrophic event occurs, the patches start to perish, the tube starts to perish or the valve stem begins to separate from the tube.

How do you know your repair is good? Swapping the patched tube back in provides a means of testing.

I haven't done a bad repair since I was 13 and that was quite a while ago. No need to test them.

Patch a tube is easy, reliable and will last as long as the tube. Spare tube only if pouring down and patch not adhering or tube has other issues such as valve detached.

At what age do tubes deteriorate?

 

[Yellow Saddle]

When I used to do a lot of Sunday runs with clubs the riders who got the most punctures invariably had loads of patches on already.

I can interpret this two ways:

1) Voodoo allows for a disproportionate number or glass shards to attack only previously patched tubes.
2) The patches were crap to start off with.

Let me throw some salt over my shoulder before I flip a coin and decide which of the two would satisfy Mr Occum.

At what age do tubes deteriorate?

Tubes made from Butyl don't deteriorate from age. It is the presence of Ozone and stress that deteriorates them.

So you are dropping down at hill at 45mph and your years old multipatched tube decides to have a catastrophic failure.

I would suggest less likely to happen that a multi patches tube. I respect your knowledge so perhaps you can explain this for me, when I patch a tube and pump it up there is an obvious stress area around the patch, does the effect the tube, Michelin technician told me it did so what is your opinion.

My opinion is that the Michelin technician didn't have a degree in polymeric chemistry.

My instinct would have been to ask him to explain said stress.

My conclusion is that he was either:

1) Ignorant but sincere
2) Greedy and wanted to sell tubes.

Since I don't have much to go with other than a brief second-hand recount of the encounter, that my conclusion is inconclusive.

Now, where did I put my patch and solution? I have work to do.

You can see the stress point, can you explain what is happening?

 

[Ming the Merciless]

You simply don't get catastrophic failures because a tube is patched. So whatever straw man theory you have, clearly it is not evidence based. Patching has been a good reliable repair method for over a hundred years. New tube every time is just a way to get you spend your money on tubes rather than beer. More fool you.

Actually, I can't see the stress point. Please point it out.

No fool here, 2 flats in the last ten years, tubes changed yearly and put to other uses. As for beer, in one end and out the other.

 

[slowmotion]

I'll patch mine with "old school" patches at least three times. I'll stop if the patches are really close together or if one of them needs to be close to the valve. It's one of the few things that anybody can do to make something as good as new. That's got to be good.
