Is there a handy-dandy "understanding gears" reference available, either in a library or online? I am perfectly happy calculating gear ratios and such (several years as a cyclist did that), but otherwise you might as well be speaking Cantonese. Unless you *are* a Cantonese speaker, then it sounds Norwegian.

Thanks.
