Nitto makes a handlebar that can handle some offroading, and yes, its part of the North Road Family. If you do not like the mre upright posture(that is arguably more appropriate for casual touring), you can flip it over and have a slight drop, but still have the much more comfy wrist position. The only downside is that they only sell it through rivendell and can be a bit expensive.
