How many patches?
« on: September 30, 2019, 06:35:42 pm »
So while this question applies specifically to my mountain bike,  I think it's relevant to any bicycle. I just put the sixth patch on the tube to my mountain bike (dang goat head thorns).  All the previous patches are holding fine and this one probably will too.  Still, I wonder when is enough.  How many punctures do you repair before replacing the tube? I know the time comes to just toss the tube and get a new one but I'm kind of a cheap guy.

Thank you.

Six. Very arbitrary number. Less important for me now for my touring bike, as that current bike runs tubeless.

42. The answer to so many questions.

I haven't patched a tire in a long time.

I don't count the number but I stop when I have to put a patch over an existing patch.

No particular number, when I am not comfortable with the location or coverage of a patch.

That or when I am too lazy to do a patch and instead just put in a tube.  Once a tube comes out and is in the tool bag, it is likely to get rejected before the next trip if it has patches.  I like to start tours with new or near new spares, but never pull out an installed tube just because it has patches unless maybe I am installing new tires.

OTOH, I love the tubeless setup on my MTB so much that at some point I'd consider stopping the use of tubes altogether.  I have not explored that option for touring and road though.

I know I've topped a dozen.  In all but two cases*, the previous patches held until an unrepairable hole struck.  That can be something like the aforementioned puncture too close to a previous patch, puncture near or separation of a valve, or a blowout that's too big to patch.

* I'm about half way through a box of 100 Rema patches, so between that and the 4-6 patches in little repair kits I've used on tours, that's a failure rate of probably one in 35-40 patches.

You need to replace the tube when any new patch has to overlap an existing patch. These will leak. Also it is time to get a new tube if any existing patch starts to peel.
