So the stock headset on my Steamroller was due for a change.

I bought (and subsequently had installed due to not having a press) this FSA Orbit headset: http://www.amazon.com/FSA-Orbit-Thre.../dp/B001HS2RKU

I put the bike back together myself and I have a little bit of vertical play (millimeter or less) in the fork that I can't seem to get rid of. I checked the top cap and stem to make sure they were as tight as I could get them and it still seems like I can't get it to seat properly.

So could it be:

a bad install (crown race or otherwise)?

the star nut being out of place for the new headset?

some trick for seating things properly when putting together the front of a bike?
