Eric,
I have a Superbe long cage mounted to my all-chrome, all Superbe Schwinn Voyageur 11.8. It's a very fine unit that shifts flawlessly, as were all the Superbe line of components. I believe it is later in the Superbe line as it has the satin finish with the lettering screened on as opposed to the older units that had the name SunTour in relief.
