The more expensive Scaninis were build in Italy, and had ITA bb threads; the cheapeer ones were build by Martens and had English threading. Eddy Martens or Bart Verhagen (owner of the Scanini name) told me that they made the profiled tubing for the cheaper frames themselves, with a machine to press creases into the tubes. I had a Belgian made Scanini, and its certainly a different feeling frame! But I prefer the Italian ones, super quality.
