The Roam 2 would do fine on cinder running/hiking trails. I would probably do fine on double track fire road and well maintained trails. I would not take jumps with it, drops of greater than a few inches, or rocky terrain. The fork isn't made to handle the impacts or track the ground changes on much more than relatively smooth surfaces.

The gearing is functional, but won't work well under load or otherwise repeatedly harsh shifts. It's a light trail recreational bike. Use it for the purpose that was in the mind of the designer...
