Derailleurs: too numerous to even think about listing...

This masterwork is the single greatest source of information on derailleurs that the world has ever seen (and, quite probably, ever will see).

Frank Berto towers over the subject like a colossus, but mention should also be made of his esteemed contributors; Ron Shepherd, Raymond Henry, Walter Ulreich, Tony Hadland and Gordon Selby.
