1. $250 is a very good price for that bike on CL, I bet its gone by now.
2. It looks like a 25" frame to me.
3. Neither of these bikes have campy cranks, don't know what tradtimbo is talking about.
4. To the OP, you have a very nice bike with a campy drivetrain. In my opinion I think $350 is a reasonable price for your bike. $250-300 is okay and a good price to get off ebay. $150 is an insult.
