The Zeus Alfa 72 Especial is a reasonably faithful copy of a 1966 Campagnolo Valentino Super. Campagnolo had ditched this design in favour of the Valentino Extra in 1968 - but that does not seem to have diminished Zeus’ enthusiasm for it - even in 1972.
The Alfa 72 Especial is strong, nicely finished and terrifyingly dull.
