I use a Mirrycle. It's great. I love it.

Hubby has a Third Eye BARend Mirror that he had on his hybrid. It's not so good on the road bike. It doesn't stick out far enough, so it mostly reflects his hip as he pedals. He's going to get one like mine eventually.

P.S. Not to insult you, I really do like his bike. I actually think HIS bike looks like more of a girls bike and mine looks more like a boys. But, I have to love what I have and what I ride, so I keep telling myself mine is cooler! LOL

I did tell him in the bike shop "no fair! I'm the one that likes to ride the most and you get the best bike"!!! (mine was used and his is brand spankin new)
