I've had these Zeus cranks for a long time and have never known what group they came from. When i got them they were triples so i took the old chainring bolts and small ring off which i still have. I actually have a Zeus Criterium crankset box but i never thought it was the matching one for my cranks, today i looked again and the image of the cranks on the box shows doubles with a different Zeus logo, but stamped on the box are three chainring sizes: 40/46/50 or 51. I have all of those. Should I put the old chainrings back on and sell them as triples with the box? or should i leave them as is. I also have a Zeus bottom bracket that's in really nice condition, i believe the threads are for a Zeus frame. Should i include that as well? Oh yeah and i have a stack of 13 extra Zeus chainrings.
