Bars do indeed turn lock to lock without interference.

Angle is quite comfortable.

Imagine a small gokart wheel. Place your hands at 10 and 2 o'clock. Note your wrist angle. Or just relax your arms while seated and bend your elbows slowly upward. Now bend your elbows inward till your thumbs are about 8 inches apart. When your wrists are relaxed your thumbs will be closer together than your pinkie fingers. The narrow bars provide this same relaxed yet narrow position. Among recumbent racing bike builders this position is sometimes called "preying mantis". It is very commonly used.

Behind the instrument cluster are two hose-clamps. They clamp the bars onto a horizontal saddle. This allows adjusting the hanging angle of the bars. You can swing them like a pendulum until you find the most comfortable wrist angle. Then you tighten the hose clamps.

I could weld the saddle to the bars. I have avoided this because of issues involving fumes from chrome. Such fumes are much nastier than fumes created from steel to steel welding.
