I think I set the crown race and lower and upper cups correctly, they all look square to my eye. The headset has the ball retainers plus an upper and lower "o-ring". And 2 spacers (one is inset w/ the upper adjustable cup) and a locknut of course. I have both ball retainers oriented correctly. When I attempt to adjust the headset, it binds up as I tighten it, but also is too loose when I check fore/aft / side to side play. I'm pretty sure the frame is milled square. What is up, is it an O-ring thing? Should I give up and let the LBS check it out?
