The Colnago Master is a road bike frame produced by Colnago since 1983. It is also the last frame that was still produced in steel, after that mainly aluminum and later carbon were used.
It is a frame that has sparked a revolution in the cycling world, thanks to special innovations including the hexagonal section of the cold-drawn tubes that gives the frame greater rigidity. This shape is also known as the “S4” Gilcodesign profile designed and manufactured exclusively for Colnago.

Het Master-frame is ontstaan uit het idee van Ernesto Colnago om een product van de allerhoogste kwaliteit te maken dat ook het merk Colnago symbolisch zou kunnen vertegenwoordigen; in de eerste plaats dacht Ernesto aan een buisdoorsnede die herinnerde aan het beroemde klavermerk dat symbool staat voor het logo van Colnago.
The project was developed by Gilberto Colombo, who in the same years, in close collaboration with the Aubert & Duval steelworks, experimented with the possibilities of a new micro-alloy: the SCV, from which the cold-drawn pipes of the type 15CDV6 were later developed.

These tubes have been produced exclusively for a long time by the Colombo company, Trafiltubi srl, which also produced steel pipes in the most diverse shapes and with different thicknesses (under his innovations Colombo had also developed a machine, the hydraulic mold “T15”, which can give the tubes different thicknesses).
Colombo developed a tube with a hexagonal cross section and variable thickness, specially for Colnago, which he called S4 (or “star profile”), called Gilcodesign. He was also closely involved in the development of the first model of the Master frame and the subsequent variants up to 1987.
Colombo also came up with an interesting innovation regarding the handlebars for the Master's track model, released in 1985: the head set is enclosed in a “cartridge” which provides a beautiful aesthetic design.

Het gebruik van deze hoogwaardige legeringen en de hexagonale buizen had onmiddellijk effect. In 1983, het jaar waarin de Master werd gelanceerd won Giuseppe Saronni op een Master de Giro d’Italia. Het was het eerste succes van het frame dat nog steeds vermeld staat tussen de beste technologieën die een revolutie tot stand brachten in het wielrennen.

From 1991 Colnago also used Tanghe's Ultimate Superlight tubes instead of the Columbus tubes.

From 1989 the Masters receive a straight fork, called the Precisa which initially received a lot of comments but was soon adopted by all bicycle manufacturers. The advantage of this fork is that it gives the bike more resilience.

After all these years, the Colnago Master is still in the Colnago catalog. The frame has undergone several changes over the years, but the Master remains the top of the range for Colnago's steel frames.
For example, in the 2007 model, the rear forks are made from carbon fiber, while in the 2008 model, they were reduced to steel.
The Colnago Master in all its variants can be considered a cult product and has become a collectors item for vintage racing bike lovers.
