G Joannou Cycles is in northern NJ, Northvale NJ to be exact. They're right off of the (in)famous Route 9W, the popular road for NYC racers to ride on, maybe 15 minutes from the Tappan Zee Bridge. They are the Jamis folks. I believe Joannou is the name of the family that owns and runs the company.
I didn't know that they had a self-branded line at one point.
