What a bummer...I have racing Zero's and the same problem. Seems they didn't update the wheels since this first occurred. I'm 86 kg and on rough roads (usually descending fast) the problem is worse. I've experienced high speed shimmy more times because of these wheels than in my whole life cycling. I swapped the front wheel for a Giant P SL1 and I don't have the issue...
I wonder if this is enough to consider them faulty. The question is what to replace them with.
