Hm, maybe I'm misremembering this but I thought SRAM was an American company that acquired Sachs at some point. And yes, Sachs has enormous history but they did not as far as I know morph into SRAM, they basically ran until the end of the line and sold to the highest bidder. I remember their 'Sachs Ultra WC', the Rolls Royce of mopeds from the 80's. Very nice stuff.
