Usually I can see the flint or glass responsible for most of my interruptions but dribbling water on the partially-reinflated tyre and watching for bubbles finds most of the rest. The remaining 1% suck.

It's helpful to locate the source of the puncture to prevent getting a second one from the same object. When the object isn't obvious, you can usually locate the jet of air from the hole in the tube, then that gives you the approximate position of the object (assuming you know the tyre's position relative to the tube, eg because you match the label with the valve).

I agree, Although it’s hard to get tubes at less than a fiver a time.

You're not looking hard enough.

See you in the new bargain inner tubes thread!

And planetx do frequent offers on tubes. Vavert branded which go outdoors sell sometimes.

Glued or glue-less, I find that on tubes for thinner tyres, where the curvature is greater the ability of the patch to bend and stay bent matters the most. There’s a lot of for-glue patches out there that will come unstuck.

Just tried a couple of GP-2s on a tight curve. Quite impressed.

Is there no quality threshold then?

I wasn't impressed with the Vavert (as seen at PX and GO) because they didn't take patches reliably. Half odds tubes with the orange label seem ok, but I'd still rather Schwalbe or Impac with the superior Woods valves.

I carry the PartTool 'stickers' and had just assumed these had taken over the 'old fashioned' boxes with glue, crayon, patches with orange bit around the edge.

I've been using these for the past 10 years and have tubes with multiple punctures repaired by them in all condition and still going strong.

I've never had one fail on bikes running psi of 60-110.

I've been using the Parktool stickers for 5+ years now without issue until I left a bike out, all day in the sun, in the most recent heatwave (30+) - 2 peeled and lifted on the same tyre in the same way at the same time... Must have been the heat?

I started this thread after repairing a puncture on my daughter's bike discovering that I was very low on normal patches and deciding to try using some glueless patches from Wilco that someone had given me. I said I would feed back on the success or not. Well last week I noticed that her rear tyre was once again flat so thought to myself "that patch didn't hold". However I discovered that she had another puncture and that the patch I had fitted was holding perfectly. So, so for so good.

unionised patches, them; one off, all off....
