The Colnago Formula 1 is a high-quality road bike known for its lightweight frame and advanced engineering. It was part of Colnago’s lineup in the late 1990s and early 2000s, often praised for its handling and performance. The Windsor crankset suggests a potential aftermarket or component upgrade, which is common in the cycling community.
