Any question answered...

Anything you do find is going to be 95% polemic and 5% science, is that what you need?

Academically based polemic is fine. It's a pretty big deal, to be fair.

That's the trouble with a lot of climate change 'debate' - no economics. A few right wing nutters have pointed out what a dumb idea it is to ignore economics, but as far as I can see all of the politicians, scientists and NGOs have big vested interests in doing something (anything), because the economically literate solution of doing next to nothing leaves them out of the loop, and therefore cut off from the power and money they crave far above any desire to do any good.

I don't really follow this. As in, I don't understand what you're saying not that I don't agree with the point.

Search for James Lovelock on YouTube, plenty of stuff there, from his initial position, to the one he now adopts.

He's the chap who wrote this mildly alarming piece in the Independent.

He's written a number of books on the subject: Gaia: The Practical Science of Planetary Medicine, The Ages of Gaia, Healing Gaia, The Vanishing Face of Gaia and The Revenge of Gaia.

I remember Testes recommending Wippermann chains but I'm not sure if that was limited to the SS chain.
I tend to use Sram chains for most stuff. The PC890 is £17 and the PC870 is £12 both from CRC.

Cheers.

Their dérailleur chain is good too, but millions of KMC fans can't all be wrong. I'd say it was between those two, choose according to prejudice.

Cheers.
