Colnago Master Bicycles

In the early 1980’s Colnago began experimenting with crimping main frame tubes to increase stiffness, reduce weight and improve performance. In the mid-1980s, Colnago and Gilberto Columbus developed the Gilco Master tube profile which was a round tube that featured four distinct symmetrical flutes through the central section of the tube and resembled a 4-sided star.
This tubing was used to build a new Colnago model called the Colnago Master. This groundbreaking tubing was the defining special feature of this new frame model and its unique shape makes it easy to identify. These specially profiled tubes were used in all 3 tubes of the front triangle (top tube, seat tube and down tube).
The Colnago Master is undoubtedly the evergreen of cycling history. First released in 1983, five different versions of the Colnago Master were manufactured until 1998 (Master 1983, Master Più 1987, Master Olympic 1991, Master Light 1994 and Master X-Light 1998).
The Master series undoubtedly represents a peak in steel frame manufacturing, but on the other hand, also marks the end of the steel era in the bicycle industry.

1988 saw the introduction of the Precisa fork which led the way for all of Colnago’s future fork production. At the time, its straight blades were revolutionary and improved the absorption of vibrations coming up from the ground as well as giving better overall control of the bike.

Any Colnago Master Più produced after 1988 is most likely going to be found with a Precisa fork
