If you look closely at that black tab, you'll notice that the slot you use to slide it onto the metal piece is NOT in the center of the tab. That's not a manufacturing error. It allows you to change the distance between the spoke and metal piece which then, of course, changes the angle of the knob relative to the wheel so you can have it perpendicular to the face of the wheel so you have a smooth, even turn from lock to lock. /forums/images/graemlins/cool.gif
If you didn't know any better, you'd believe that some thought, planning and engineering went into this little green knob, wouldn't you? /forums/images/graemlins/wink.gif /forums/images/graemlins/smile.gif /forums/images/graemlins/grin.gif
