Hmm, I was wondering the difference between Threaded headsets and Threadless Headsets and what difference it'll make, And i also wonder which brand of headset should i choose and also if a frame like Giant Reign which has a integrated headset, must I still buy a headset? or I must buy a Internel Headsets? If if i must buy a internet headset I would be really pleased if someone would tell me which model. Im looking for a lightweight and as cheap as possible headset.

threaded has a nut on top that threads onto the fork steer tube...threadless are absent of threads and have a clamping stem that maintains bearing adjustment. threaded usually use a quill stem

integrated and internal HS are different

Many people will advice but few no of the lightest and best ones. they are plastic but very strong for long times. I have used for many months.

headsets are not on there page but call and they will sell!

The Giant frames with internal headsets comes with the headset. If you want a new one to fit such a Giant you can get one from Cane Creek (any of the ZS models) or FSA (one of the Orbit models). Good headset companies include Cane Creek, Chris King, FSA, Hope, Race Face, Ritchey, and Syncros. It really is hard to mess up a headset . Chris King does make an internal headset, but it often requires modification of the frame to fit, so it's generally not an option.

are you buying a full bike or a frame? why do you even need to worry about HSs if you're buying a fully set-up bike?

Oh I See, So which mean if I want to buy a Giant Reign Frame, I dont need to buy a new headset right?

if you are buying just a frame, and it is an integrated HS frame, then you most likely need to buy an integrated HS

Giant does supply them with the frameset (I should say: at least in the US, I haven't checked elsewhere). I was considering buying a Trance frameset a couple weeks ago, so I discovered this .

Thanks
