Attach Kryptonite Messenger Mini+ I got a Kryptonite Messenger Mini+ with a rear wheel extender. Really great design except for one thing: there's no way to clip it to the frame. The clip that I have depends on fitting on the straight side of the U, which would make using the extender impossible. 

Is there a convenient way to attach this to the frame?



Additional description: the issue is that in the picture above, the right hand side is straight, and can accommodate the standard aluminum clip that Kryptonite sells. However, the aluminum clip is rigid, and cannot turn around curves, meaning I cannot put in on the left, and slide it onto the right side. The right side is curved (how it's held into the lock) and the clip mount cannot fit onto the right hand side. However, if I attach it on the left, then U-extender cannot slide past the clip.
Is there a convenient way to attach this to the frame?


According to Diane Craig at Kryptonite support:


  The Flex frame bracket will not work with the Messenger Mini +. We do not make a spline for the Messenger series to attach the lock to the bracket. The Transit H bracket will work it mounts to the handlebars and the lock hangs down"


Pictures of the bracket in use were few and did not include the Messenger Mini+.


Bracket empty
  

"convenient" is in the eye of the beholder.
