Someone letting my tyres down?

nich

I've had a few punctures in the last couple of weeks.

One of them was a bit strange, as it was fine when I arrived at work. That evening I moved the bike from our office basement to our shared garage, and then headed out for a quick pint.

When I returned it was flat.

Ugh, I thought. Anyway, I just assumed it was a slow puncture and changed it.

I've just got around to looking at it again as I was going to patch it up, and to my suprise there's nothing wrong with it! I've done the under water test and nothing, no bubbles.

I'm starting to wonder whether someone at work let my tyre down :shock:

Not necessarily - I have had one or two "mystery" leaks - tube etc absolutely fine, pumped up and held air next time around. I put it down to a valve issue - not screwed the presta valve down completely.

Yeah most likely is that

The valves on these particular tubes do come lose on a daily basis. Oh well, at least I can re-use the tube 8)

Depends how slow it is as well, i just repaired a inner tube and unless i blew it up about twice as big as normal you could not see a leak at all, it was there after a lot of fiddling though :shock: .

Could also be a dodgy valve or like you say dodgy workmates, fit a razor blade to your valve caps to be certain .......( yes i am joking :P )

Makes a few notes...

You didn't inflate with a CO2 pump by any chance?

alternatively, you may have whatever caused the original puncture still in your tyre. Run your finger (slowly) along the inside and if you suddenly start gushing blood - problem solved

Surely if ever there was a time to suspect, this was an act carried out by a very pi$$ed off puncture fairy !
