  An enquiry re what I believe to be an early 1970's Zeus Criterium chainset, specifically the bolt circle diameter (BCD). Using the late Seldon Brown's centre to centre of chainring bolt multiplied by 1.7 formula I get (within the limits of my ruler and visual accuracy) 118mm. However I've seen a int ernet reference to a 120mm BCD.

What do list members know?

Thanks in anticpation.
