I never saw a lot of it at races back in the early 80s, but my first serious road bike - a 1980 Olmo Nuovo Super Sprint - was completely decked out in Zeus 2000. That included the fancily-milled and drilled crankset, drilled rear derailleur and a seatpost with around 30 tiny flutes. I bought it for the princely sum of $425 in 1986 in Phoenix, AZ at Bicycle Warehouse.
BTW, did anyone ever see anyone racing with PMP bent-arm cranksets? I must have seen two or three of those at every race back in the day. Weird.
