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.

you mean like this?

Thanks.

If this doesn't work out, you might look at a Click Stand. We ride a tandem so conventional stands don't work that well. This does the job for us. https://www.click-stand.com/

+ 1 on kickstand if you don't mind having a stand that's not integrated onto the bike.

I have one of these in black for my bike, I like it. https://www.youtube.com/watch?v=wcwdVywqp_k

I have the Greenfield rear stabilizer kickstand for the last 5 years and 15,000 miles, good design, light weight, powder coated, made in the USA.

Here is a link to some picutres from another bike tourist.

I once had an a question about product availability and emailed Greenfield and received an prompt reply, they subsequently traded me products, at no charge.
The reply and subsequent correspondence was from Mr. Greenfield himself !)

Good products, competitive prices and great customer service.

there is a Pleitcher which uses 2 bolts thru the chainstay to hold it.

some EU bikes are built anticipating them. retrofits without planning, unsure.

25 years ago I found one stamped with Bridgestone's name on it..
it locked in the down position.. a good thing ..
