I'm looking for an actual measurement of the ERD for the above rim and am hoping someone can help. Velocity lists the rim at 591.0; my attempted measurement comes to 586; and Spocalc contains the caveat "Measured 596.4. MEASURE TO BE SURE!"

Thanks in advance.
I use the Velocity claimed 591mm and always get good calcs using Wheelsmith Spoke Length System. It sounds like your 586 is more of a measured i.d. Remember, "E" is for "effective". If you don't have rim rods or something similar you can't really measure the effective dimension as it is measured from where the nipple sits. . . .
