have no experience of mixing Zeus with other brands so cannot comment there
no one in europe was designing to JIS standard back when Zeus tapered square chainsets were first created
other readers are sure to be able to give a better answer to your very reasonable question

Thanks!
My Zeus spindle looks more like an ISO type. Zeus is supposed to have copied Campanglo a lot so maybe they tapered their cranks like it. However pre '94 Campy it was closer to JIS than ISO. This would explain the fit gap if Arregui crank is added later and it is ISO. But being Arregui and Torrot both basque companies it appears to me more natural have used originally Arregui cranks and not Stronglight. I tryed upload a few pics but I need to have 10 post done for that.
