I've been reading the threads about hub design, specifically flange position and spacing, with a great deal of curiosity. Thanks for all the comments!
I've got a couple of questions, first how are the dimensions measured? I'd guess that flange diameter is measured to the center of the hole, but I suppose one could measure the inside or outside edge of the circle. Same question on flange spacing, do you measure to the midpoint of the flange or to the inner or outer edge?
Second, I've got a nice Dura Ace 7700 rear that I'm going to build into an Edge 1.38. I know I could lose a few ounces by using a White Industries, DT, Alchemy, etc, however, the DA appears to have the best flange spacing of any hub discussed in the other threads. Both spocalc and Shimano's documentation list the Left/Center as 36.9mm and the Right/Center as 21.1mm . The Right/Center measurement appears to be bigger than the 16mm-20mm numbers I've been seeing from the boutique hubs, however they could be wrong (I haven't measured for myself) or they could be measured differently than is standard.
Third, the build would be with Sapim Race DS and either CXRay or Laser on the NDS. The hub/rim is 28 hole. I'm a 170-175lb sprinter (in season!) and this would be a crit/road race wheel. I'm thinking this will be plenty stiff.
Thanks for any insights you pros might have.
