The avocet is listed as 74 mmm, in Sutherland's 4th edition. This is good; 74 mm is much more easily gotten than Campy 100 mm; I think still in use.

I think that the min. tooth count for Campy was 32, but Merz may have done better. 74 goes down to 24 tooth. ++++++++++++++++++++++++++++++++++++++

Anyone know the BCD of the inner ring on the old Avocet/Ofmega triple? Anyone know a source for campatible rings?
