Interesting. I came across this same exact bike at a LBS for under $1k.
Not certain if I think it'll have great all-around usage, but it does look like a sexy beast.
I think the point they're trying to make to you on this bike, by the way, is that the geometry and chainstay on this bike is not 'comfy' for longer rides. Its a quicker bike than a road bike, but will be very sketchy, imho, as its designed to go straight, very fast. You'll also find yourself feeling constricted in the chest on the shorter frame.
A 56 has a 31 and some change clearance on the top bar.
