    How is it calculated, and what does it mean?

    Oh, I get it now.

    More gear inches=stiffer gear. Hence the constant penis size comparison jokes. Coolbeans, thanks for the link.

    In the context of fixed-gear, what is a reasonable GI for a reasonably in-shape person (but one who has been riding with gears and has never ridden FG.)?

    If you have access to a geared bike, try it out there. 42x16/17 is pretty common.
