Hi, im new to this forum so im sorry if i posted in the wrong place.
Mod Note:
welcome @Silver. S I've moved your thread to the mechanic section.

So i have a Cannondale Chase 2 2008 frame and i need a headset for it. (Including cups)
Im planning on puting a manitou circus comp fork on it with a straight 1-1/8" tube.

So my question is what headset should i get?
(Preferably around 50$)

Thanks beforehand
