Some questions have come up on the Zeus 2000 crankset I have up for auction on eBay
My understanding is that the slots that went all the way through the crank arms were just done on the very first versions (1977?) and were quickly changed to the slots that only went part way through the arms. My quess would be because there was a breakage problem with these highly stressed parts.
Anyone have info or recollections on these cranks?
