Spacers below stem

How tall are you and what size bike are you riding, you maybe an in between size ie: could be riding a large in a compact style or an xl in a more relaxed style, what you are saying sounds like you need to go up a size.

I had similar problems particularly with lifting on the front wheel my setup was almost identical. I tried everything you are talking about, I went up a size , increased bar width 650 to 720 and reduced stem length 110 to 90 and the bike rides perfectly no lifting and 1000% better control and much improved technical capability.I am 6ft2" and it's a large frame FS
