I don't want to start a Flame War but I need a good handle bar type of mirror that can out live the rough roads in my area. All the Chip and Gravel roads do a number on most mirrors that I have bought over the years. Right now, I do good if I get two years out of a mirror before it starts to fall apart. Does anyone have any ideas of what mirror can stand up to the beating it gets on the rough road I must travel?
