I have a third eye bar end mirror (round, 3", convex, about 15 years old, the new ones look the same as far as I can tell) on my new flat bar bike. I loved it on my old drop bar bike, but on the flat handlebar it is less than perfect: it doesn't tilt toward the inside as far as I would like, so I need to lean a little toward the mirror to see directly behind me (as opposed to behind me and to the left which is what I see from my normal position). This takes some of the fun out of having a mirror.

Can anybody recommend a sturdy bar end mirror that can be aimed more usefully than the one I have now? I have seen the Mountain Mirricycle but am not crazy about the way it sticks up above the bars, not sure how that would work with bar ends.

Try a new model one. I have two one flat bar bikes and they rotate plenty far enough to get a good view. I suspect something about the design has changed since your was made that is not evident just looking at it.

Ditto...that's the best mirror option for any bike.

Maybe for any bike,. but not necessarily for any rider...

If you have impaired vision in your left eye a bar mounted mirror allows for a better view.

I would love to be able to use a helmet mounted mirror... but putting it on the right would not be very effective for my usual lane position.

Thanks, that's interesting. I will get a new one and give it a try.

Ditto on this. Depending on the fit, it's pretty sturdy, even for drop bars. On my Lemond, it stuffs in quite nicely. On my Specialized, it's too loose. YMMV

I understand your point, but if you have impaired vision in your left eye, how is a mirror on the left side of the bike, farther away from your eyes and with a lense that usually makes 'items in mirror closer than they appear', help anything? Perhaps a bar-mounted mirror on the right?
