I'll see what else I can dredge up on your Pacifica. It's mid-range - but for a PUCH that's good! Even the SEARS imports were worthy in the USA & Canada. You can do the right click/view image trick. It just says it's alloy or something. Those Austrians are a strange & wild bunch! LOL.

Regards rear derailleur - get it a nice replacement. I'm running a Shimano Ultegra on my Puch. Before that I had a Suntour Mountech. My first was a Huret Titanium Duopar.
