It is simple, and elegant. The best solutions usually are! They are engineered! Took lots of measurements, lots of attempts, lots of test rides. Went through quite a few materials, hardware, techniques. I filled a garbage can with swarf, scraps, failed attempts. The simplicity was distilled from sweat and hard work. SpyderAnn did not want people to drill or modify their Spyder in any way. That added an element of challenge, as well. The result works fantastically, and people have put thousands of miles on their Spyders, and the mirrors are still rock solid!
