it depends on what you mean by off road - it definitely doesn't have a suspension, so if you really want to do mountain biking type trails... it's not what you want. You could maybe look into cyclocross type bikes for that.

but if you just want to do gravel or unpaved tow paths, the trek is going to be fine.

the trek is aluminum... aluminum is "harsh" when you hit bumps - it's a stiff material that transmits vibrations. The Jamis that I mentioned & Zen has is steel... Steel's a more "comfy" ride because steel sort of flexes and absorbs vibrations.
