i just put one of the new FSA Orbit Option headsets (-1.5 degree cups) in my old Sunday and i really like how it rides and feels but it makes this annoying clunk that scares me a little. the headset installed fine, everything looks straight, and there is no play in the headset but it makes that noise. even when i just pick up the front end a foot or so and drop it. anybody have any ideas out there??? thanks!
