A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the diamond frame. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes.

Instead of following his family's farming business, Ernesto Colnago chose to work in the cycle trade, and was apprenticed first to Gloria Bicycles at the age of 13, and subsequently taking up road racing. After a bad crash ended his racing career, he began subcontracting for Gloria, and opened his own shop in 1954, building his first frames the same year. While building frames, he remained much in demand as a racing mechanic. He was second mechanic on the Nivea team Giro d'Italia under Faliero Masi in 1955, eventually being employed as head mechanic for the Molteni team of Belgian cycling legend Eddy Merckx in 1963.
