I almost never see a Thorn for sale in USA.
I am trying to figure out what the difference is between the Sterling and Nomad. I did not look at the brochure, I don't have a very fast internet connection.
I can see the brake cable is above, not below the top tube. Regarding the recent thread on headsets, this appears to be the Cane Creek labeled FSA. There is a pair of oddly spaced bolts under the downtube that are not spaced properly for a water bottle. From the photo I can't quite tell if it has a reinforcement under the downtube behind the headtube that is smaller than the reinforcement on the MkII Nomad. Maybe it was a lighter duty version of the Nomad?
