Says 610 on the rim label. I get 614 using Spocalc's method.
Do rim manufacturers generally include the thickness of the nipple head in ERD?
If they don't, and since Spocalc does, that would explain the discrepancy.

ERD is nipple seat to nipple seat across the rim-what kinda nipp shouldn't matter-
Try a wheelsmith rod to measure-

The "effective" in "effective rim diameter" is there because the dimension is *not* taken on any rim
surface. ERD is correctly measured to the "ideal" location of the ends of all the spokes.For most that includes nipple heads, as shown on
