What are the cranks? Reason I ask is that there are a lot of 'track' and 'single speed' cranksets knocked out cheap that are actually doubles and to get a 42mm chainline you need to mount the ring on the inside of the spider, which of course looks a bit cack in comparison but that's why they're cheap.
If this isn't the case (I don't ever remember seeing miche doing this on-the-cheap type of c/set), then I'd definitely check frame alignment as per the Sheldon link above.
