There is an error in the listing, since the bike in the picture has a triple, not a double crankset. Notice the 3 chainrings? It comes with 9 speed Sora, and the crank is Sugino.
This bike was approx $850 new.

I have two of this model (same bar tape and color!), and they are a fine first road bike if it fits and operates ok.

Somewhere between $250 and $350 seems reasonable for it now.

Oh, don't even think of trying to use the clip-on aero bars on the test ride!
