I saw a superbike with them on recently and it looked very cool. It looked more like a racebike without the large rearview mirrors. I'm not sure if they workwellthough. Anybody have any experience with them? Thanks

 

i'm using a bar-end mirror on my left clip-on and i absolutely love it

its placed over the bar itself so as to minimise look-down time and when angled right it provides a clear view of my rear as far as the double-yellow when i'm inside the HOV lane

get the one made by CRG with a bar-end adaptor ... it is kinda expensive so you may want to get the Motrax which is a CRG knock-off sold @ CycleGear

 

I use the motrax and like it.
