Width from centerline to flange = 30 mm (rear), 34 mm (front)
Flange diametre (measured to the spokeholes) = 67 mm
Spoke hole diameter = 2.6 mm
These are for double-sided Suzue ProMax loose-bearing hubs, double-fixed, 120 mm. You can measure the distances yourself with a caliper or just a decent ruler on any rim you come across. For symmetrical hubs (double-fixed, fixed/free) just measure the flange-to-flange distance and divide by two. For asymmetrical hubs (single fixed) put them in a frame and lay a ruler across the top of the flanges so it lays against the seatstays. Just measure the distance from left seatstay to left flange, right seatstay to right flange, and between the flanges. Whatever the two center-to-flange distances are, they have to add up to the total distance between the flanges.
The center-to-drive-flange distance will be equal to the flange to flange distance minus the difference between flange-to-seatstay distances, all divided by two.
The center-to-non-drive-flange distance is equal to the flange-to-flange distance minus the center-to-drive-flange distance you just calculated.
For a single-sided high flange Dura Ace 7600, the difference between flange-to-seat stay distances is 11 mm and the flange-to-flange distance is 71 mm. Subtract 11 from 71 and divided by two, and your center-to-drive-flange distance is 30 mm. The center-to-non-drive-flange distance is 71 mm - 30 mm = 41 mm.
Hope that's all clear.
