I'm a big fan of bar mounted mirrors. I've used the velcro mount in the past but my new bike has a backsweep to the bar ends... makes the velcro type almost unusable, (won't align properly, constantly adjusting). Tried the Mirrcycle,
http://www.mirrycle.com/mirrycle_mirrors.php. It works Great, much better than I imagined it could. Stable, good view.... I'm glad I found it and can again enjoy riding with a good rear view, without constant fiddling.
Edit: BTW, I have no connection to the company, just like the product.
Regards,
