The alloy selected by Columbus | • | Nivacrom for Zona: The Nivacrom steel for the Zona series undergoes a series of processes and treatments, which, after drawing, homogenize the mechanical characteristics of the tube, making it uniform along the longitudinal axis. This makes the fatigue behaviour and weldability of the material excellent.
| The characteristics of the Zona tubes | • | Tubes with increased thickness walls for "Over size" frames | | • | Moderate weight and notable strength thanks to the shapes, which are introduced also for the tubes of the rear stay | | • | Elevated reliability and fatigue life | | • | Main triangle in Nivacrom, rear stays in steel alloy. | | | Reasons to choose Zona
| • | Zona is the design which finally allows for a reasonable compromise between weight, strength and life of the frame. Thanks to the particular operations to which Nivacrom is subjected and to the new sizes that also stiffen the frame laterally by means of suitable grooves, it is possible to obtain an end product with good characteristics of lightness and a high efficiency. | | • | | |
