So going from this, it's a Canadian product but probably made in Japan...these models show some with pretty high-grade tubing, and one with SL. I saw one for sale a few years back that was very unimpressive, but it was advertised as "Italian" and so I was disappointed straightaway. It was surely the rock-bottom model.
Not to be cofused with "Fiorelli" which IS an old Italian marque and they built for pro riders and sold bikes as "Coppi" back in olden times.
