Reasons to choose Altec2/Altec2 Plus

  • Athlete: Altec2/Altec2 Plus offers extreme lightness, together with the widest tube range. This allows the manufacturer to make the right frame for any specific use.
  • Framebuilder: The mechanical characteristics of this light aluminium alloy are enhanced by heat treatment after welding. Maximum values of mechanical resistance and fatigue life can be obtained. Altec2  tubes are reliable and long lasting if properly assembled following Columbus advice (A special booklet is available for correct assembly of Altec2 Plus). Altec2 offers different megatube shapes to customize the frame geometry.
