I hadn't heard of another bike besides the Schwinn CrissCross using this RD design.
I used a CrissCross with one of the chainstays RDs this summer for an around town bike and likes it a lot. It's lower-mid level SunTour components, but they shifted perfectly fine.

Surprised it won't shift well with Accushift Command shifters. It was a neat design since it hid the RD and kept isn't from being knocked around as much as a traditional placement.
