Thanks for that. I seem to have a gap between top of frame and headset, there is also a wobble which i can't seem to iron out. Many thanks
Both bearings need to be pressed in the headtube cups.
Look calmly and carefully what prevents this at each element.
For instance:
Does the fork makes contact with the bottom of the headtube?
Preventing the bottom bearings to be pressed in.
Maybe you need to put a crown, or the bearings has not the correct height.
Is the dust seal making contact with the frame?
Preventing the top bearings to be pressed.
Add some washers under the dust seal.
Does the top cap makes contact with the steerer tube(cut too long) or the star nut or compression nut?
Preventing the stem/spacers to press on the dust seal.
Add a 5mm or more spacer on top of the stem to test.
