Oria was an Italian tube manufacturers thar gained some prominence in the late 1980s, after Moser used their tubing on his world hour record frame. The tubing was found primarily on Italian bicycles. Like most manufacturers, they produced a range of tubing. If you know the tubeset name, I may be able to provide some specifics on the tubing, like weight and wall thicknesses, so that you can relate it to a comparable Columbus or Reynolds tubeset.
