Europe is big. From a German POV Sturmey Archer were exotics, and allegedly not that good compared against anything (well maintained) by Fichtel&Sachs. I don't even remember what was on my early road bikes anymore, but certain it was neither Campagnolo or Shimano.

Later on I rode Campagnolo, they were reliable and easy to maintain. Anything Shimano I cursed and avoided like the plague. Because that was sensitive shit, not good to maintain, and degraded fast. It was like it was made to be thrown away after few uses, just to save a few grams.

All that aside, this gave you a real advantage: https://connexchain.com/en/ :-) They were called different at the time, just Wipperman maybe, but didn't really matter.

You just asked your dealer for the good chains made in Solingen, and got these.
