Recently bought a pair of these folding bar end mirrors Fresh out of the box Here are few pictures of them installed Thoughts: The expanding metal sleeve that goes inside teh handlebar that came with this set of mirrors was very tight tight and did not want to expand. If I had a pair of pliers I would have bent out the flanges but I didnt, so I stole the sleeves off my old mirrors and used them. installation is easy, just shove them in and turn your allen key The folding feature is pretty nifty, however, no matter how tight you make the section that is holding the pivoting ball, the pivoting arm will always move when you try to fold the mirrors in. In the near future I will be taking some loctice to it and gluing the shit out of the pivot. Also I noticed that a couple of the allen screws were a little loose, but nothing a couple of turns of a hex key cant fix. Whilst riding with them I was surprised that there was no vibration! and once adjusted correctly, the rear vison was fantastic. Have not filtered with them as of yet though so I am not sure of car mirror clearance would I buy these again? definately.
