I bought a 'locking spacer' [QBP] and put it 1st thing above the upper headset.
so fussing with stem and spacers didn't have the fork coming out.
that made a nice improvement with mine..
The bike: Koga a world tour ready trekking bike.
... on modern frames, I like the smooth flow, visually, between fork and frame.
made possible by integrated headsets.
