I don't know that it's ever been confirmed as Truth, but that's the well-accepted rumor. A related rumor I heard is you can identify the Ciocc made Concordes by the presence of an Italian flag braze-on on the top tube. I have an '88 PDM Team edition, and it certainly looks like a Ciocc of the time. It rides beautifully. (This reminds me I need to take some pictures of it!)
