It was a beautiful day here is Sydney, and the club was heading for Palm Beach, up the north coast - a lovely ride.
But on my way down to meet in the city (a 50-minute journey), I acquired a puncture in the rear wheel. Couldn't find a nail or anything, so couldn't repair it, and turned for home. Took 5 stops at petrol stations plus two of my gas cylinders to get home!
I have now taken the back wheel off (a major operation), and located the hole. But it is probably not worth repairing. The tyre has done 6000km, and the instructions for the repair kit say a repair is only temporary, and the tyre should be replaced as soon as posssible. So now I will 'phone a few shops to see what is available at what prices. A web search indicates that Savas are good, but Michelin Pilot City probably the best.
Can't wait to get mobile again!
