Hi, this is my first try at installing a sealed-bearing headset. Model is FSA Orbit MX 1-1/8 threadless.

when I dry fit the bottom part, there is a gap at the top of the fork race, maybe a couple mm, but it doesn’t look right.

if I take out the little metal collar, the gap tightens a bit but the action isn’t as smooth. So that doesn’t seem right either.

Any thoughts?
