I'm looking for options and opinions on mirrors that can survive the slips and falls that seem synonymous with winter biking. I'm now on my third MTB handle bar mirror this winter. It seems when I find something slippery I always go down on the left side, causing mirror damage, even when using 26x2.1 inch knobby tires with 4 rows of studs.
The first mirror was a bar end Mountain Mirricycle that survived a number of "minor" slips and falls, just pivoting out of the way, before a major fall broke the glass on the bar end handgrip.
The second mirror was something I was able to fit to the Mountain Mirriycle arm, and it worked until a "home plate slide" broke the Mirricyle arm last week.
The third mirror is a Blackburn Multi Mirror, but it looks like it would snap rather than pivot out of the way in a fall, so much so that I took it off before yesterday's aborted snowy commute. (Something about not being able to pedal in snow up to my hubs made me give up...)
I've looked at eye glass mount mirrors, but didn't find any that would work with my winter goggles in place. I've also looked at helmet-mount mirrors, but didn't find any that were compatible with my helmet (Giro Eclipse).
If you use a mirror in winter, what have you found that survives the seemingly inevitable falls?
