effective top tube length
An all-purpose, high performance tubeset, manufactured in Cyclex
steel, a top quality chrome molybdenum steel which has been cold
worked to increase its strength.
These tubes in this set have short butts and are super finished to
remove any surface defects. A wide range of tube diameters and
shapes allow us to build frames to the customer's exact
Technical Data: 60 - 70 Tsi
Progetto Zona: custom, competitive road, and MTB frames
The alloy selected by
Nivacrom for Zona: Nivacrom is patented by
Columbus. This is a steel alloy in which vanadium and niobium -
precipitating in the metal matrix - block the grain growth during
the elevated overheating of the welding containing the decline in
the mechanical characteristics even at temperatures above 1000°C.
The material developed for the Zona series, is subjected to a
series of operations and treatments that, after drawing, homogenize
the mechanical characteristics of the tube, making them uniform
along the Iongitudinal axis. As a result, the fatigue behaviour is
Mechanical characteristics: Rm = 1000 N/mm2,
Rs = 920 N/mm2 Ap5 > 10%.
The characteristics of the Zona
- Asymmetrical tubes with cylindrical reinforcements
- Moderate weight and notable strength thanks to the new shapes,
which are introduced for the first time also for the tubes of the
- Elevated reliability and fatigue Iife
Reasons to choose
- Athlete: 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
Iaterally by means of suitable grooves, it is possible to obtain an
finished product with good characteristics of lightness and a high
- Framebuilder: Zona alIows for the construction of reliable
frames which are easy to realize, both for the working of the
tubes, the welding and the squaring operations of the frame. Thanks
to Nivacrom, Zona takes fulI advantage of all the characteristics
of this steel which has been especially developed for cycling.
