It has a threaded headset.
I too am worried about the distance and riding pose. But as I said before if I don't like the way it feels it's not like I'll be out a whole bunch of money. I'm sure I can find a usefull application for the bars in the long run. My only concern was my brake/shifters working out ok. I can't afford the sweet shimano Nexus Inter-8 rear hub and grip shifter that Dead Extra is rockin'.. Oh my how I wish I could give that bad boy a try.
