This clever machined hunk of anodized black aluminum will mount your Hondo Perfect Squeeze onto jsut about any handlebar dimension. You can even flip the "teeth" of the unit and the backsides of it will crimp down on even the smallest of handlebar crossbars. The unit also comes with a portrait adapter plate if you prefer to run your phone in the landscape position. The whole kit and caboodle will set you back $40—machined with pride in Montana.
Of course you could always go instead for the RAM Mountsa 1" ball adapter, which works with a host of RAM accessories, and makes going from landscape to profile a 2-second adjustment.
