The Jim Felt engineered "drop cranks" that Paula used. If she were racing today the forum would be agog with excitement and threads dedicated to them and (almost) everybody would be rushing out to buy a set.
I recall that the idea behind the drop cranks was that on the downstroke pedalling force essentially "tipped" them forwards thus effectively lengthening crank length on the downstroke. Big chainrings to go with her 24 inch wheels.
They did increase stance width or "Q factor" but supposedly PNF preferred the wider stance.

p.s. best thread ever! There was so much innovation from the 80's through the 90's that if the UCI hadnt stifled innovation what bikes, bars and positions we would be seeing now.
