Help on calculating spoke length
Rather than quoting figures for the right and left flange distances from the Locknut centerline distance, they quote a "flange to flange" distance, along with an offset, for some mysterious reason.

This image: http://issuu.com/novatectaiwan/docs/novatec_hub_dimensions should help translate their "Flange to Flange" and offset figures to be right and left flange distances. In the case of this hub, your left and right flange distances are:

Wl = (F.T.F/2 + Offset) = 36.00mm
Wr = (F.T.F/2 - Offset) = 22.40mm


Using the dt swiss calculator, I calculate 292 and 291mm spokes for building a triple-cross wheel with your selected components.
