7400 HS.
I installed the DA stem and tightened up the HS.
Wait a minute! If the shop installed the headset, why are you messing with it? You should have just
installed the stem.
Quoted message said:If I just snug up the top cup so the steering is nice and easy, the fork moves in the steerer
The steerer is part of the fork; it can't move relative to the fork. I think you mean the
steerer/fork rotates within the headtube (as it should).
Quoted message said:and I can see the top cup move. If I go tighter on the cup so the fork don't move, steering gets
really hard.
Are you tightening the locknut against the upper cup? You need to be very careful as it's VERY easy
to get the HS too tight (and quickly end up with indexed steering). You want to start with the
adjustment a little loose. Tighten the locknut while holding the upper cup with a headset wrench.
Squeeze the front brake, and rock the bike while listening for clunking noises (indicates HS too
loose). Then readjust in very small increments until the clunking just disappears. But the shop
should have done this when they installed the HS.
Quoted message said:I assume the steerer tube was properly faced as the frame came with the Record HS installed.
You mean the fork crown and headtube; the steerer tube does not get faced.
Take it back to the shop that installed the HS!
