OK ive measured the ERD on the z-rim 389 or is it 397,just i know there is a slight difference in thickness of the rims here is my measurements for 389mm erd

large hub

Hub Flange Diameter = 63mm
Hub Center to Flange Center = 36mm
Hub Spoke Hole Diameter = 3mm
Number of Spokes in the Wheel = 36
Cross Pattern = 4

spoke length = 194

smaller hub

Hub Flange Diameter = 48mm
Hub center to flange = 24mm
Hub Spoke Hole Diameter = 3mm
