Okay, I'll take the contrary position.

I tried a glasses mounted mirror. I didn't like it at all.

First, it pulled my glasses down on the one side. Those of you with astigmatism or bifocals (I have both) know how that screws up your vision. Second, no matter how I tried adjusting it, all I could see was my own shoulder. So why should I use an "obviously" superior product that only ruined my vision and didn't show me what I wanted to see anyway?

I went with Mirrycle's Road Mirror for STI.


It mounts out of the way of my hands, yet right where I instinctively look for a mirror. Within days, I bought one for my second bike too.
