Has anyone seen the rearview mirror that velcros around the brake hood? In other words, it's removeable so that you can use it for the commute but not have to show up with it for your Saturday morning road ride?

You mean like this?

I use one of these :

It is a BELL item made for a kids bike. Since the diameter of the clamp
is smaller than the bar of a roadbike I snap mine on the bar under the hood minus the
screw and use a rubber band to keep it on. It looks bigger in the pic than it looks
when its attached to the bike. Adjusts on the run...comes off in one second flat !
At 4.00 its the best set-up Ive ever used. Im going to post a pic of my Surly in the
commuter section next week if you want to see what it looks like on a bike.

Yeah, that looks like what I have in mind. Where'd you find that?

The one I use isn't attached with Velcro but has an adjustable rubber strap. I got it at REI.
