Well just this Saturday we went for a metric and I had a puncture. For a change I decide to swap tubes and haul the brand new tube out of the ziplock bag. WTF! Stem too short! I was able to inflate it halfway with a helluva lot of effort. It would have been easier/faster to patch but once the whole thing is mounted who's gunna go back? Plus doofus here rode with his saddle bag wide open at the start and lost the pump and patch kit somewhere.
