Well, I have used it on singletrack as well, but it wasn't that technical...it's not all-day, backcountry capable, im sure of that, but it will hold its own on anything found around here. I think that after that "fire-road", the urban assaults that I have done, and the single-track that I have ridden, it is more than capable on "normal" NE Ohio single track. And, it uses a threadless headset...
