I use the aspire velo tech mirror above and really like it. I like it keeps its position as you ride, but it only works on road bikes. I also noticed terry now sells a similar mirror that does pop on the end and doesn't require unwrapping the tape, but I don't know if it works as well as the aspire velotech one. I just tried to find you a link on the tery mirror but don't see it anymore. I never adjusted to helmet mirrors.
