I just tried to measure the BCD of a Zeus chainring with pencil, paper and ruler, but did not get a consistent BCR ... the radius is either 59 or 60 mm.
Sutherland's 3rd edition sais 120. Zeus Catalogue 102 is no help
Does anybody have a definitive measurement? Were there ever any non-Zeus inter-changeable chainrings?

BTW: Anybody out there with a good 36T to sell or trade? BTW #2: Eddy Mercks will be participating in this weekend's Eilat Triathalon.
