Hello,
When I am trying to install my stem into the head tube I am having difficulty. If the head set nut is not tightened the stem will insert into the tube easily, after it is adjusted the stem seems to bind/tight. The stem will also slide into the fork tube when not installed on the frame.
This is a new build, but the parts are from the correct so no issues of compatibility.

My questions are:
1. should the nut be left loose and stem inserted and then tightened?
2. Do I need a taller shim in the stack incase the nut is binding on the fork tube?
3. Is there a sequence to install....do I leave the nut loose and set stem height and then tighten?
Regards, Ben
