I'm building my first wheel and have a H Plus & Sons Archetype rim and a Shimano Alfine 8-speed hub gear. Looking at the spoke calculations, I have the Shimano spec which indicates a Flange Diameter of 104.3 and an P.C.D of 92.6.
But on the web, I'm reading that 'flange diameter' and 'p.c.d.' are one and the same(e.g.: here).
So if I'm using spokelengthcalculator.com, what should I use in the left/right flange diameter?
