    Now then guys!

    Hope someone can help!!

    Forks out of box, steerer cut to length and ready to go with a headset i have had kicking around for some time. FSA XLII orbit!!

    I can’t for the life of me remember which order the things goes in when you’re stacking it all on to the forks. I know the bigger bearing is the lower one and smaller bearing top one.

    Its the crown races i can’t remember. There are 2, one just aluminium (one piece) and one anodised gold with a split. Which is top and which is bottom?!

    Other thing is, once that is all together in the correct order, is the adjustment via the star nut (effectively pulling the fork up against all the bearing surfaces, pressure being applied to the stem or stem spacers rather than the steerer tube)!??!?!

    Hope someone has put one of these together before and can remember the order……….

    Smaller bottom race fits into the fork crown, then lower bearing race. Lower cup covers this and has a tubular piece that fits into the lower end of the head tube of the frame.

    Top race also has this tubular piece and this fits into the top of the head tube. Upper race fits into this and the top cup sits on top.

    If bearings are different sizses, the larger ones will bear more of the load and sit on the bottom race, as you say.

    Tightens via the star nut, as you say, once the stem is fitted. Once all done, tighten the stem bolts on the steerer and if you want, just loosen the top washer.

    I always shove in loads of grease and wipe off the excess.
