Goldtec Hub Failure

With a bit of imagination you can picture the two crossing spokes pushing on the radial spoke of the triplet, which transmitts this to the edge of the flange. In reality the forces should be too small, and the the bracing angle far too small, for this to cause the failiure (IMHO). I've heard loads of postive reports regarding the quality of Goldtec hubs, maybe they are having problems controling this quality?

I'd be interested in seeing some stress images of some hubs with different lacing patterns. Surely there are some out there on the interwebs.

You do mean in bending, right? I think that spokes are so flexible that you can assume they only transmit tensile forces. At least, that's what I would do if I were building an FE model of a wheel. (Sorry if I missed something).

Where is that contour plot from? Looks very interesting.
