Lemond Fillmore 08 vs Fuji Track 08 vs Charge Plug 09

Is the Fuji really a 'track' bike anyway? I guess the seat tube angle is a but steeper than the one on the Fillmore, but it pretty much just looks like a road bike. The dimensions aren't all that different than the Fillmore. The Bianchi Pista looks more like a track bike to me.

A track bike is a bike that can be used on the track which could be a range of geometry. As long as the BB is high enough to be allowed on a track then fine. The Fuji doesn't come with brakes, has a track based fixed gearing and a higher BB than a road bike so to me would suggest it is for a track. Not sure why it needs to look a certain way?
