Tom Hayes asks:

Does anyone know approximately when triple chainwheel cranks came into = existence and which manufacturer developed them? Was there such a thing = as a triple cotterred crank? And was there a corresponding rear = derailleur to the introduction of the triple? =20

The earliest I know is the Campagnolo NR triple matched to Shimano GT, = but I'd like to you know if there were others, earlier than the = Campangolo and which rear derailleur went with it. --------- I could be wrong, but I believe I remember seeing steel triples on 5-pin circles in the CycloPedia catalogue, ca. 1963, and surely the TA CycloTourist was available that early.
