Can one of you chime in and give me some tips on setting the headset mechanism correctly?

Seems like a smart system that is unfortunately smarter than me.

I built a Top Level earlier this year and honestly don't recall doing anything out of the ordinary with the headset. What's up with yours?

Its like the fork and headset arent quite tight enough around the headtube.

normally you can just crank down on the top cap, as it is screwing into a stationary fork nut, but this one is attached to the expander deal.

whats the trick?

Yes, I can help. First make sure the screws attaching the stem to the steer tube are loose. Next, you put in the expander, you turn the allen screw that is deep in the headset, not the actual top cap (which should be loose at this point). So, you get it in there pretty snug. This acts like a star nut. Of course you know that the steer tube has to be below the lip of the stem. Now, the black top cap is threaded and screws over the expander plug. Hence, tightening this black top cap pulls the headset tight by yanking up on the steer tube. Turn it until all rattle is gone when you drop the front wheel from an inch or so above the floor.

Tightening the top cap until the rattle is may not be sufficient with the Fondriest headset. The headset uses 36 degree chamfered cartridge bearings that work just like an interegrated headset bearing.

The headset has a large o-ring in the top bearing race and a 3.5mm spacer that goes on top of the o-ring. This o-ring requires some extra force to compress it a bit. I find it necessary to tighten the top cap substantially more than I would a Campy headset. I tighten it enough to cause a bit of drag when the fork is rotated, then back off a fraction of a turn.

Tightening the top cap just enough to eliminate rattle can leave the headset too loose. If you hit a decent sized mismatch in the pavement, you may hear a "thwack" sound, indicating that there is some movement going on. Others have reported this problem. The solution is to increase the tension on the top cap.

I changed my spacers and reset the crown race, this at least took the uneven pressure off the top bearings. However, does anyone find the steering very quick (carb level U 107, full carbon fork? Has anyone replaced the wole thing with a King? Both Will @ fondriest and 2 of their authorized shops stated any headset would fit?
