The characteristics of the Zonal tubes

Elevated strength/weight ratio thanks to the use of lightened tubes in the central zone
Very good TIG weldability
It is necessary to perform an artificial ageing treatment after the welding of the frame in order to improve the mechanical performances (6 hours at a temperature of 90°C followed by 4 hours at 150°C).
  Reasons to choose Zonal
Athlete: Zonal allows for the production of frames with a moderate weight and adequate characteristics of strength thanks to the use of the Megatubes.
