So ... I just swapped the default Cannondale stem for a shorter FSA SLK stem on my new Synapse Carbon. The conical spacer plus one 5mm spacer below, the rest on top (as it was before).

Somehow I've introduced some horizontal movement between the fork and frame. Checked everything is tightened using a torque wrench, and everything is pushed down as tight as possible. This is the limit of my powers, what am I missing?

what am I missing?

Is the headset adjuster cap hitting the steerer when you apply the bearing preload? This is likely if the stack height of the new stem is less than that of the old one.

I understand about half those words. The new stem is taller than the old one (I had to lose a spacer). Pretty sure it isn't hitting though - there is about 2mm of spacer appearing above, as it was before.
