Just got a Jamis Aurora Elite which I think of as a tourer. It has Avid BB7 mechanical disk brakes. On my old Jamis Aurora (with cantilever brakes) I had a Greenfield rear-mounted kickstand which is much more stable when the panniers and rear rack are loaded.

Is there a rear-mounted stand which attaches to the chainstay forward of, and the seatstay above, the disk brake assembly?

There must be! If not, somebody could make good money designing and producing one as disk brakes become more prevalent, especially on loaded tourers. Traditional kickstands aren't stable enough and 2-legged stands are heavy and clunky.

I appeal to the collective wisdom and search skills of the swarm.
