Third Eye Bar End Mirror Mount

I really like the Third Eye Bar End bicycle mirror but the ID of my handlebars was too large to get a secure fit. After a season of constantly adjusting my mirror I was a bit frustrated. At a stop light I decided to crank it down as tight as I could and of course I cracked the mirror. I like the mirror enough that I ordered a second but decided to make a new expanding mount for it before it arrived. This is the result... Note this will only work on handlebars that have a larger than 20mm ID
