|Does anyone know how to true a dura ace 7701 wheel? Is it the same as a conventional wheelset?|

Download the .pdf and read the part about tension to start. And no, they are not like conventional wheels. They are actually a pain in the ass in my opinion. But you need to true them from the hub but the concept is the same, if the wheel pulls to one side, you need to take tension off that side and add tension to the other side. They are really difficult to get perfect because they use the paired spoke design and there aren't as many spokes as a conventional wheel, but make sure you stick as close as possible to the recommended spoke tension on them. I have seen a rider loose one spoke in a Dura-Ace wheel. It seemed to me (it happened really fast) that the wheel collapsed one full revolution after the spoke broke. That's a problem with high tension paired spoke designs. They work fine until there is a problem, then once the tension is unbalanced, the whole wheel goes quick.
Again, that's all just my opinion, but it's based on working on these particular wheels in the shop, and seeing one fail first hand.
