The pics don't expand so difficult to determine the condition of the bike. This has a reynolds 531 double butted main frame and looks to be hi tensile steel fork and stays. Given what I can see of the paint job, this looks to be a PKN 10. Not peugeot's top of the line but a very good bike. It's odd seeing the mix of campy and shimano stuff on this bike. That's certainly not what it came with originally in the US; are you located in Europe?

Condition and location matter in valuing a bike. I'd say this is worth somewhere in the neighborhood of $200-$250.
