In the mid-1970’s Zeus was caught in a pincer movement between, on the one hand, the Campagnolo raising the game with the 1973 Campagnolo Super Record, and on the other hand Triplex making cheap aluminium Campagnolo copies. Time was running out for Zeus’s policy of slavishly copying old Campagnolo models.
Zeus’s response was the 2000 groupset - a genuine attempt to make the very best components in the world - and this is the Zeus 2000 derailleur from that groupset.
It is basically a steel derivative of a Campagnolo Record, but it has a titanium hanger bolt, highly cut away knuckles and looks to have been machine-gunned by Al Capone.
Although Zeus repeatedly claimed that the Zeus 2000 was lighter than the Campagnolo Super Record, this example weighs in 3g heavier at 187g. Nevertheless, for Zeus to get this, largely steel, derailleur down to 187g is an astonishing, but ultimately futile, achievement.
