I have a Hungarian Schwinn Heavy-Duti. It only has subtle differences from the originals, even has no name S-2 tubulars on it. (tubular rims, not tires

) It does have a unicrown fork with curved blades, ala early MTB style without canti posts. It has a welded frame instead of EF, but you almost don't notice it right off. The tubing bends are EXACT to the older Schwinn specs, with curved tapered stays, etc.,,,,BD
I know, not a road bike, but is made in Hungary.
