Context: Since the 1980s, while Colnago continued to produce high-end steel bikes, they began to produce cycle frames using material other than steel, including titanium, aluminum, carbon fiber and mixed materials. One unique frame from this period, the Bititan, has a dual titanium down tube. Crimped and oversize tubes were used on the Tecnos–one of the lightest production steel bikes produced. Similarly crimped oversized aluminum tubes were used on the Dream frame. In 1981 Colnago prototyped the CX Pista–a full monocoque carbon fiber cycle with disc wheels, which was shown at the Milan bike show. Subsequently, Colnago worked with Ferrari to develop new carbon fiber technology, and Ernesto also credits their engineers for challenging him regarding fork design, which led to Colnago's innovative Precisa straight-bladed steel fork (1987). Colnago also experimented with multi-material frames, including the CT-1 and CT-2 constructed with titanium main tubes, carbon fiber forks and rear stays, and a similarly constructed (although short-lived) Master frame constructed with steel main tubes, carbon forks and stays.


Question: Given this paragraph about bicycle manufacturer Colnago, what Italian automobile company did Colnago work with to develop new carbon fiber technology?
