This advert comes from a supplement to the August/September 1985 edition of La Bicicletta. The supplement celebrated the 1985 World Championships that were held in the Veneto region of Italy. This is home territory for Campagnolo and Gipiemme, and not-so-far-from-home-territory for Galli and Ofmega.
As well as the Ofmega Premier derailleur, this advert also features the beautiful Ofmega Mistral chainset (always a favourite of mine) and the innovative Ofmega Sintesi pedals. The text claims that the b-pivot, the p-pivots and the parallelogram pivots of the Ofmega Premier derailleur are all made from 'anti-friction material'.
