The distinctive feature of this model is the junctions of the main tubes, which are immediately recognizable for their arabesque shape. The complex workmanship of these elements is carried out by Rauler (an Emilian brand born from the merger of the founders' names, the Gozzi brothers, Raoul, and Reclus). Active since the 1970s, Rauler initially specialized in pantographs for racing bike groups and components. They formed a fruitful collaboration with Colnago as early as 1970, building frames and details like the aforementioned arabesque junctions.
