The seller probably just bought it in 2004. as it appears to be s a 2002 Bianchi BCM5, which was a Canadian market model with an MSRP of $1229 CDN. Specs indicate a drivetrain consisting of Campagnolo Xenon 9 speed derailleurs paired with a Sugino XD crankset, which is a perfect match. Spec brakes were Bianchi branded CMP-1, which I'm not familiar with but also appears to be a match. Wheels were Formula hubs laced to Rigida rims. The frame material is simply listed as Aluminum, while the fork is CrMo, so the fork does appear to be OEM. There was a similar model in 2003 listed as BCJ7, with the only spec difference being Miche hubs laced to Fir rims and a slight price increase to $1319 CDN. There were no Xenon equipped models listed in 2004. Since 2002 was the intro year for 9 speed Xenon, we know it's no older that.
