Threadless stems can be flipped, possibly achieving 2cm alone. Ain't happening with a threaded "7" stem. Even if the thread less fork has been cut to have no room for spacers, virtually infinite combinations of stem angle and length are available. Heck, if you have a threaded stem needing adjustment, the easiest route may be to toss the threaded stem and replace it with a threaded to threadless adapter. From there you can put the bars almost anywhere you want.
I did say it was possible. You don't think buying a new stem or
fork or stem raiser plus spacers, "some doing"? I do, certainly vs loosening a locknut and pulling some more height (to the min insertion mark) out of the stem shaft ... I'll double down: some doing. I have NEVER seen the stem that was negative angle in the OEM position allowing 2cm of height free for the flipping. Let's call this one a draw.
