• I was calm and thinking it through! And then when those things didn't work I got a bit irate and sad. My brain cannot figure out how it happened in order to reverse the process.

    FixedStar - thanks, I would love to do that. Alas I don't have a chain breaking tool, and if I did I wouldn't know exactly how to use it. One of the many bits of bike maintenance I have failed to learn.

    I'll give it another go in a day or so, and after that I guess I'll chop it off with some secateurs and try and put a new one on.
