Just to re-state, data sheet attached earlier is for Open Sport (although file name says Open Pro - I named it wrongly). Data sheet quotes spoke support diameter to be 606mm, but you need to add about 1mm each end for the distance from the spoke support to the bottom of the slot of the nipples. Therefore, approx 608mm effective diameter (ERD).
