I'm getting a headset for a friend of mine who has a Giant Sedona. What type of headset should I be getting? It is a threadless, and that's all I know. I've been looking at Chris King, FSA, and Cane Creek. As I understand it, Cane Creek makes cupless, integrated headests, which take a specifically-designed steering tube. Is this the type I need for this bike or am I safer sticking with FSA? I've been looking at the Orbit X.... Any ideas out there?
