Mirrors are sort of a personal thing. What works for one does not work for another. For example, I tried one of those mirrors that mount to the helmet but having that thing hanging out there drove me crazy. But I have friends who love them. I also tried a mirrycle, but it vibrated so much on rough roads (and chipseal) that I could not really see anything in the mirror. You may have to experiment a little to see what works for you.

After much trial-n-error, I ride with one of these stuck into the end of my drop bar. Good luck!
