Edge 45 Clincher comes with DT Swiss Aerolite standard from Wheelbuilder although you can specify Sapim CX Ray with no additional cost ... your choice. From what I have read re the DT 190's most opinions suggest that the weight savings and ceramic bearing upgrade does not justify the additional $450 cost of the hubs. How much did you pay for the Endo Zero Ceramics? New Chris King R45s look very interesting ... about the same cost as DT Swiss 240 but a hair lighter.
