Building some new wheels finally. Just want to double check my numbers before I order spokes. Rims - Mavic EX 823 - ERD: 530 (taken from Krispy's recommendation, using 16mm nipples) Front hub - Hadley 20mm - Flange dia: 60, Center to right: 22.6, center to left: 31.4 Rear hub - Hadley 150mm - Flange dia: 60, center to right: 27.8, center to left: 32.2 Spokes: Front: 251/252mm (Gonna use 252 all around) Rear: 252mm 36h 3X w/ DT Competition spokes and 16mm nipples Only number I can't confirm is the 823 ERD. Seems to be quite a few numbers floating around. Anyone built this same/similar wheel want to chime in.
