If the pro bike was ridden a month, it prob has the mileage stated. Otherwise it might be a lot more.
Keep in mind the mileage a pro does on his bike. A (lower level) pro friend of mine asked how much longer the tires on his bike would last while we were on a ride. I gave them a generous 1500 miles, 1000 miles on the short side. For me, that would be a month or two. He said "oh, okay, I'll get tires in a week then." I protested, saying that he won't need tires for a month. He pointed out he was doing 500-600 miles a week. He went through gear incredibly fast. He would crack frames regularly, his wheels would fatigue like mad, etc.
Pros do ride at a different level than most of us. Although Phil Anderson didn't race for Toyota-United, he apparently went through a chain every two weeks. I can't imagine wearing out gear like that. I have the same chain on from a year ago and I've trained and raced on my bike.
However, I think it would be cool to own a "real" pro bike, not a replica.
and of course it would have to fit. otherwise no good owning the bike.
