My left shoulder is pretty attractive but I would rather see more of the road and the drivers who are trying to kill me. I was thinking of making up an extender with a bolt and threaded collar. The bolt would fit into the handle bar and the mirror would screw into the collar. This would lift the mirror to give me a better view. Hopefully screwing the mirror in would tension the whole unit and stop it from loosening up. Has anyone done this already? How did it go? Am I trying to "reinvent the wheel" 'cos these things readily available from bike shops (but not in FTG)? .
