Zeus did copy many Campy features (just as Campy had copied others), but the 70's/ early 80's Zeus cranks, both road and track, used Zeus's own unique 120 BCD chainrings. To my knowledge, no one else used this circle. It was just 2 mm smaller than Stronglight 93/104/105, but that 2mm makes them incompatible.

Having bought into the notion that most Zeus stuff was essentially Campag copies I went to fit an NR ring to a set of Zeus Pista Cranks (BSC 165) to find that they did not fit. So I've got two questions for you
a) what size (BCD?) do I need
b) does anyone have a suitable ring they'd be willing to part with (42-47 pref, but anything considered.
