>1980 - Development starts on the Campagnolo freewheel, a combination of aluminum, titanium, and steel with a three-pawl ratchet system; the last project that Tullio personally oversaw. The 980 low-cost rear derailleur (26 tooth capacity) is introduced (9 80 = September 1980).

So, I ask, when did six speed Campy aluminum freewheels begin to be available to larger Italian racing bike companies? Would manufacturer brochures be showing the freewheel for 1983 models? Could they? Thanks...

Ciao,
