I just go for a test ride up and down the
street, few hundred yards each way. Carry an
Allen wrench. When you get back to the
driveway, turn the bars. Repeat the test
rides until you get back to the driveway and
don't want to change the angle. I doubt I can
patent this ingenious method. I use the same
method for saddle height and handlebar angle
in the stem. Test and trial. After you
eyeball it pretty close to start with.

Why does the angle/height change from
tightening the expander bolt? I just tried to
push a handlebar and as expected this was
possible without much force. The bolt wasn't
exactly loose but it was possible to give it an
additional torque. I was tempted to push the
bar again but didn't do so. So now I'm sure it
is impossible to do, happy ever after.
