Australian DeepV ERD = 582 to flat of a 12mm standard profile nipple.
American DeepV ERD = 581 to flat of a 12mm standard profile nipple.
Difference is appears to be the while the Australian version had raw joint sleeve resulting in the nipples sitting deeper in the rim adjacent to the joint, the American version has the holes in the joint sleeve counter-sunk resulting the same seat behavior for the nipples throughout the entire rim.
So double-check your ERDs as American made Velocity's replace Australian made Velocity's...
