That's what I was thinking of when I wrote it. The new autoshifting (I forget who's releasing it) 2 speed is another option.

A QR should be possible on the Swift. Shear strength seems to be the major concern at the pivot.

(I should mention at this point that I have no idea what I am talking about )
