Regarding the stem height on the bike, I am going to wait until my saddle is leveled and the bars are also level to the ground before doing anything. I think I detect two ~ quarter inch spacers I can remove. The difference between the old bike and new bike drop is about an inch and a half. I am going to be cautious and ride it for a while and make small changes. Anything else wouldn't be prudent - not gonna do it.
RIP 41
Assuming the bars are straight to begin with, couldn't it be marked and then line up to the mark after reinstalling? I do this for my saddle. maybe not so easy for the bars.
