Sorry to hear that, jags - we've had some pretty fine weather for a while in South Yorkshire, so I've been Ripio-ing around a bit - which makes me realise how unfit I am.
Big event next weekend, I am in the support team for a group of riders cycling from London to Paris in aid of Phase Worldwide. I can mend punctures / swap tubes, sort out sticky brakes, but I have never mended a chain!! Not for the last 40+ years anyway . . . . I reckon a decent chain properly assembled is unlikely to break . . . but I'm spending an hour or so at my trusted LBS, who has offered to talk me through things, has got some old bits of chain to practice on, and lend me links etc on a sale or return basis. I must check how to sort out a wheel that goes out of true - again, not done for a while. A decent LBS is worth a lot.
All this is a long way from Frog Prince and his tour, good luck!
