What is the correct ERD for Ritchey WCS Aero (front) and OCR (rear) 700c rims? The excellent
"spocalc.xls" by Damon Rinard lists 606mm, but a note says "spoke seat 602mm." I used the straight
number for Ritchey 26" rims and the spokes were a tad long, so I suspect 602mm is correct.
Also, do I need to account for the 3mm offset of the spoke holes on the OCR rear rim by changing the
flange-to-center distances for the hub? Or is this offset too small to affect spoke length?
Any help would be appreciated (Campy 9v hubs, 28h 3x), Todd H.
