I hope this link will work, but it's from BikeForums and it talks about recall.

When I looked at my old specs, the specs reads: Xero XSR-3. It says Lite on the side. Mine was part of the 2007 group. Maybe there's hope. Though new would be nice. But, it shouldn't be outta defect.

One comment was about trueing being more difficult for the two paired spokes. I wonder if something could have happened to the rims during tire installation? Hmm...
