This is a brand new bike, and the headset and its bearings are brand new. It is a sealed cartridge headset.

I will swap wheels and see if it makes a difference, but I think the noise is coming from the headset/fork.

I was going to try and tighten it up some myself, see if that takes care of it, and then hit an lbs up if I can't figure it out. If I overtighten the headset, is it possible to break the bearings, or would that have to be SUPERtight?
