+1 for the king hubs with stans flows. I had mikesee (lacemine29) build a set for me, CK hubs, DT Comp spokes, and stans flow rims. Can't go wrong, they're strong and wide, yet still light enough to race (unless you're an uber weight weenie.. then start looking at the 355s or arches.. although both of those rims aren't as wide as the flow). The engagement on the rear king hub is amazing as well. They're pricey, but as someone else stated.. they're serviceable at most LBS and the king hubs are MUCH better than any hub you'll find on the crossmax/spinergy/etc pre-built wheelset. I don't know if I'll ever buy another pre-built wheelset, too many great custom build options out there for a similar or slightly higher price... but then again I almost always opt to build my bikes instead of buying an entire bike. Can't beat having all the parts you want and none of the fluff that only attributes to the commonly known problem of upgrade-itis!
