Well so far no one has given me an answer that I wanted, so I would say this forum knows more All responses have said 32 hole hubs.
Yeah, well... very few people have had the experience of unloading, moving, and organizing high-end bike parts by the truckload. That was part of my job at Euro-Asia. I remember most of the Dura-Ace hubsets coming with identical drilling (28/28, 32/32, 36/36), but a few were split drilling (28/32, 32/36). Also, we sold individual hubs, some of which were special-ordered with 24 spoke holes.
Well this is kinda embarrassing. I'm getting better info here than C&V! Thanks for your help on this guys. I'm gona shot for a 28/32 setup. If that doesn't come around, I'll settle for a 32/32 setup. I don't have the rear wheel yet, but I got it on ebay of all places! Item 320923498170 if you want to take a look.
