Not necessarily. It's an aerodynamic brick, but in my case it wasn't that expensive, since I have the 105-equipped aluminum-framed model from before the disc price boost. Obviously in this comparison the old Fuji is aided by skinny cylinders being more aero than fat cylinders.

There's limited room for improvement, however. When comparing the impact of tube shaping on a fat-cylinder road frame to a decent aero road frame, the raw flat-ground speed differences that result are often on the order of a couple percent. That's tangible for a lot of cyclists, but we're also talking about a kind of worst case: aerodynamic shaping has been getting expanded into a lot of non-"aero" framesets, sometimes making up quite a bit of ground versus pure aero frames at minimal compromise to their other priorities.
