Beate Habertz won the women's World Championship road race in 1978. The event was held in Brauweiler, near Cologne - which just happens to be the town of Beate's birth. Given that Brauweiler is a tiny place with only 8,000 inhabitants, this is just plain spooky.
Coming from a cycling family, Beate was an accomplished cyclist, winning 16 German national titles across both the road and the track. After retiring from competition she ran a bicycle shop in Cologne, that exists to this day, run by one Hans-Jürgen Habetz.
In terms of derailleurs, Beate is pictured using the inevitable (for the time) Campagnolo Super Record.
