My trusty bike developed a slow puncture at the weekend. As it is some 40 years since I last messed about with basins of water, chalk, rubber patches and that horrible glue, I invested in a new inner tube, only to be embarrassed to discover I was not certain how to put it on to the wheel. It seemed to be too big and as I inserted one end into the outer tyre, another section flopped out. Never mind, a return trip to my friendly local bike shop with the wheel, the tube and the outer, and a freshly pumped wheel was to hand. Only for me to find I now could not refit it back on the bike because the brake blocks were in the way and it had to be deflated again.
They say you never forget how to ride a bike. What they don't say is that you can easily forget how to fix a flat.
