I recently bought a Kuota Kredo that comes with a Carbon Fiber FSA threadless headset.
I wanted to play around with the stem height, and while unscrewing the top adjusting screw, found that I only had to turn it about 3 complete turns for it to come completely loose. That tells me that there is about 4mm of threads securing my headset: is this normal?? The expanding nut is about 30mm inside the fork tube... did my local bike shop put it together wrong, or is the screw they supplied too short??? (The screw is about 40mm long, and it starts to thread about 5mm inside the expander nut).
Am I worried for nothing? What's the proper number of turns that the adjusting screw should thread inside the expanding nut?
Alos, my LBS tightened the adjusting screw so much that the bars didn't move freely (you know, you pick up your bike from the floor and they move left to right - mine just stayed in the middle) - they weren't jammed, just not as freely moving as they should have been... didn't notice this until last week and have ridden about 300miles on the bike - should I be worried about bearings having suffered unduly?
Thanks for your help
