Yeah, the mirror-stems on the F really suck. Replaced my left one already. Design concept is good, but the aluminum threading cancels quality fosho. They should've made them of a lighter gauge steel @ the very least. JR
I just had the right one replaced 2 days ago. I rode in the rain, condensation got in, and the signal quit working...sporadically of course. It was annoying because when I hit the right signal sometimes it would flash fast, and the alarm light would flash in sync.
