Why would the Italian bikes have the Japanese components?Would it be for their lesser models?The reason I ask is I have a Bianchi road bike and am wondering if it is Italian made.It has Shimano drop outs and Suntour gears.How can you tell which is which?I was under the assumption that an easy way to tell was where the serial number was located.Under the BB-Japanese and on the seat post-Italian.I'm not sure where I read that bit of info but would like to clarify if in fact that is bs or not.
