I don't know what the other poster is talking about--I never see FXs on CL, it's a really rideable bike, and I don't think they sit much.
So I guess this is really the kind of information I'm looking for is whether or not the upgraded frame, lighter weight, and Tiagra set up is worth the 400 increase over fx3
