the frequency of cracking reported on this thread suggests a systematic problem. This is what I get paid for. Again, this is fatigue cracking and denotes the stress where the crack starts is very close to (or above) the stress required to permanently stretch the metal (defined as the yield strength). The discussion of over-tightening spokes could be a factor if the not the cause. But then it also says the design is marginal, because you don't want your part to self destruct over a critical assembly measurement that is going to be ignored by virtually every bike shop mechanic. More metal sounds in order.
