I’m on a 150 odd mile excursion today, And it’s not gone well. Someone drove straight into the back of me, as I was waiting in an ASL, and Pringled the rear wheel. Fortunately there was a little bike shop ( Chelsea bikes, next to the Worlds end pub in Chelsea ), and the guy had a 700c rear wheel. He sorted it for me there and then, superstar. I’m on the way home now, temporarily 130 quid lighter, but unhurt, and with a working bike.
