I think the whole business is in the same bed(s). Can any of the Cervelo riders in Slowtwitch land tell me the name if the Country of origin, City of origin, what the plant name is, or the guys name who layed up their bike?. I bet not many. Almost all of the major cookie cutter frames share facilities with someone else, from Trek to Colnago.
I am not too sure it makes any difference at all. But those are the facts.
