Cycling home from work yesterday afternoon, about 2/3 of the way home, whilst stood stationery in a queue of cars, I hear a chaps car break down, he put his hazards on and immediately jumped out to try push his car out the way. I shouted over and asked if he wanted a hand, as I've been there before and it's a horrible feeling, so I parked my bike up against a wall and helped the dude push his car out of the road, he was very thankful and I was on my way, my good deed done !
Literally about 2 minutes up the road, I have the horrible sensation of unfamiliar comfort, the concrete solidness was no longer there, my rear wheel becoming rather bouncy. I found a small side street where I could do the necessary, and was rushing as light was fading. Wheel off, inner tube swapped for a new one, tyre back on, start pumping up, and pssssssssssssst. I'd nipped the tube when getting the tyre back on ! 2nd and final spare tube out, a bit more care putting the tyre back on, and I was back in business.
1st puncture I've had in about 3 years using Schwalbe tyres. The rubber on the rear tyre was very low to be fair, and just the other day, having a sort out, I very nearly took 1 of my 2 spare tubes out of my saddle bag, but in the end I though better of it, close call ! I do carry patches, but today I noticed that all my glue is dried up...
Moral of the strory, don't do good deeds for others car drivers, the cycle gods will punish you !
