Does anyone know how to set one of these things up? I don't have my camera to hand, but it's the partly plastic one where the derailleur cage is moved horizontally by a spring loaded piston. On mine, the spring returns the cage to the inner (small chainwheel) position. When the cage is in this position, the lever that operates it is in its lowest position - meaning it needs to be pushed up in order to move the cage.
I can't for the life of me work out how to accomplish this with a normally set up gear cable and shifter...
