Thanks for the links, Dan. Entertaining in these days when amusement is hard to come by but, as you say, not much chop for Rohloffed-up touring bikers.
You're not supposed to turn a Rohloff gearbox upside down.
The apparently well-engineered item that fits behind the crank would upset my carefully achieved tread separation, and I would not be surprised if others on the forum, especially those with roadie backgrounds, are also sensitive to the same parameter. As for the piece of bent wire that braces itself on the crank, I don't fancy getting the anodising or paint scraped off expensive cranks, and some of my cranks are steel, so rust is a consideration. But what condemns both of these centre-stands for me is that you have to bend down to rearrange them either for propping up the bike or before you can ride off; I'll stick with the Pletcher-ESGE types which require only a swept boot to operate.
