I have straight bars there are bar-end mirrors work made for them I use the Mirrycle Mountain mirror and I wouldn't cycle without it. I've no desire for other types of mirrors - you will find fans here of all of the different types of mirror for the bike. Experiment and find what works best for you. My mirror is quite steady/stable and also inexpensive - I don't think any of the mirrors are really all that expensive which makes them easy to replace should something happen.
