How not to change a tube

I got back to my bike after work to find the front tire was totally flat. Surprising as it was fine when I got in in the morning, but at least a chance to test my Crank Bros mini-mini-micro pump, which looks far too small to move any volume of air. So out comes the tube, in goes the new one. Pump-pump-hiss-hiss... Surely my spare isn't punctured too? 
No - I'd put the old one right back in again. I didn't think that was possible - they should come in a variety of colours...

DOn't worry - on my last tyre change I managed to blow the tyre off a new rim, scrapping both the tyre (old) and the rim. Cost me £40 for a new rim and I still built it myself.
See, there's always someone who's been more of a twat than you!

My first attempt at changing a tube ..... pump, pump, pump, BANG.
No-one told me you have to be careful not to catch the tube when you put the tyre back on.0 -

Well, that's good to know . I'm still baffled as to how I managed to do it, particularly as the new one was bound with an elastic band and wrapped up in a plastic bag! It was like one of those magician's sleight of hands - which cup is the coin under? :shock:

Friend of mine tried that trick on a cold club run while we stood around freezing for 10 minutes.............and then another 10 minutes. He bought the coffees.

When using a mini-pump on the road, it's snapping the top off a presta valve that usually does for me...0

I just bought a road bike. Spent two hours last week practising changing my innertubes in my front room (so I can now do it blindfolded, just don't ask me to prove it!). Its a good job as well as the Continental GP Attack/Force tyres are very difficult to get on without a tyre lever. I kept on pinch pucturing :oops: Rather do that whilst having a beer than trying for the first time outside. 0

barbej - You practice changing you inner tubes? What, like formula 1 teams practice pit stops? Thats real commitment. Whats your best time?!
It's all good.0 -
Visions of the scene in Platoon where they have to strip and re-assemble their weapons blindfold. Barbej slamming his wheel down on the table with new inner installed "126 seconds, sir yesir"
Have you found that as the number of beers you've had goes up, your "performance" drops, so to speak?0 -
I went on a bike maintenance course at the weekend, but had virtually the whole of Edinburgh Bike Co-op come down to see what I'd done after they heard an explosion echo out of the basement that we were working in whilst I was changing a tube!!
Made the old ears ring for a while, but as it was the first thing on the course it also woke me up a bit.
Strange as I've changed loads of tubes before and never done that, but did when I had an instructor with me.0 -

Too right, though I ditched the mini-pump in favour of CO2. Last straw saw a valve snap off and jam in the mini-pump which I couldn't dislodge rendering my second spare inner tube useless. Could never get more than 60 PSI out of the thing anyway. Wouldn't mind having a frame pump for backup but can't find a good place to keep it.0 -
On the frame - no? Or am I missing something? :?Shmo wrote:Wouldn't mind having a frame pump for backup but can't find a good place to keep it.0
