“Yes, the Formula 1 was 1972 only. It was 3rd in CCM's lineup of four adult, lightweight, 10 speeds. It was replaced in 1973. The Formula 1 had replaced the Grand Prix, which had been in existence since 1966. Grand Prix was the name for races within the Formula 1 race series, so the model name change maintained a degree of continuity while signifying a major change to the bicycle. That change was switching the main tubes from hi-tensile steel to the thinner, lighter and more resilient Reynolds 531, though in the lower plain gauge variety....In the European tradition, the 1972 line now used a small diameter bottom bracket shell with threaded cups...Mechanics viewed the 1972 change as a positive sign and, in conjunction with the Reynolds 531, was viewed as evidence that CCM was trying to raise their game in the "10 speed" market.
