    FSA Headset assembly ?

    I disassembled the headset and can't remember where does the spacer go
    Please see attached image.
    The spacer is (2)
    Does it go between the frame and the Upper Bearing/Compression Ring (1), or between the bearing and the top cover (3)

    I have 2012 Niner One 9 Hydroform with integrated headset.
    Niner says it is "Cane Creek IS42/28.6|IS52/40 integrated (Campy style) headset"
    But it is written FSA all over the place ???

    Looking at the Niner WWW site, I cannot see the spacer even showing in the picture (again this is the Cane Creek, I have the FSA)

    that looks like a headset spacer. it goes between your top cover and stem.

    I am having some issues with the newly installed RDO fork
    I noticed a small rattle at the top just where the headset cap and the steerer meet
    I can push the bike while holding the front brake and feel the movement with my fingers touching that area and I definitely feels it while riding.
    Any idea on how to resolve that ?
    Also does anyone knows what's the model # of the FSA integrated headset originally bundled with the frame ?

    You probably need another spacer or need to cut the steerer tube shorter. Tightening the top cap must put tension on the bearings. The spacer can go between the top cap and the stem if you like the current height and don't want to cut.

    Thanks, I believe that I have enough spacers...
    I have about 30 mm of spacers - one 5mm on top and the rest below the stem
    That leaves about 5 mm or so gap between the top spacer and the steerer compression plug top
    I am reluctant to cut the steerer tube short at this point...
    The Top cap preloads the bearings. I tighten it till the fork doesn't rotate, than back up a bit till it is free to move, then I tighten up the stem bolts.

    My previous shock had approx. 7-3/16" length and I used 2- 5 mm spacers - one below and on above the stem
    The RDO fork came with approx. 7-3/4" steerer tube.

    I believe that I resolved the issue.
    I placed the spacer - #2 in the OP, in between the top bearing and the top cover.
    #1- I can tighten the compression plug bolt pretty good without ever locking the fork movement.
    #2 - no more front/back movement at the top.
    I will take it to a spin tomorrow and see how it goes.
    BTW, the RDO fork is a dream ! it is precise and confident inspiring.
    It is equally great on the climbs and descents - makes the bike VERY stable
    I highly recommend it !
