I've been using this
Sunlite cruiser mirror for a few years, and while the mirror is great, the attachment sucks out loud; the locknut I use still comes loose with the lightest tap, causing the mirror to flop around like a dying fish. I can't find a bracket to replace that strip of soft steel, and I can't find another mirror I like as much. Everyone and their cousin makes mirrors for flat bars, drop bars, helmets, and glasses, but I guess swept bars are just too confusing. I did try a helmet mirror, but the hole in my field of view made me twitchy and I never could get it adjusted right.
So, anyone know of a good long-reach mirror?
