3/32' v 1/8' ?

RPM why carry extra weight?

My thoughts exactly, I think the chain, cog and chain ring probably stick another half pound onto your bike.

I have also heard that the really good stuff (read accurate, fixed specific, runtout-less chainrings etc) tend to be 1/8th (?)

RPM too much thinking about things that have already been thought about by many other people (and those thoughts endlessly documented) and not enough riding make Jack a dull boy.

If you have any links to this endless documentation that would be cool, all I could find was inconclusive forum threads on various boards.

Anyone else got anything better than the usual 'don't think about it' epistemological cowardice ;)
