Columbus Minimal Fork 1" or 1 1/8" non integrated

This new monocoque fork from Columbus is called Minimal, with its essential and sober line, it has been developed for traditional head sets,
particularly for steel frames, as their essential lines dont so well complement integrated forks.  The progressive curve of the fork blades dampens
vibrations and guarantees great handling stability including in extreme conditions.

Characteristics:

  • Carbon monocoque fork

  • Composition: unidirectional T700 Carbon Fibrer

  • Carbon steering column 25.4 L=300 mm or 28.6 L=300mm non integrated

  • Forged dropouts in AL 6061 T6

  • Rake: 45mm

  • MEETS THE NEW EUROPEAN SAFETY STANDARD: EN 14781

Columbus Expander Bung:

The clearance recovery system of the steerer has been made especially to be able to adapt to the internal diameter of the fork column. The length was designed to be able to involve the entire closure area of the handlebar stem. Thanks to a series of expanders, the hold is greater and better distributed along the internal surface of the column.

Characteristics:

in CNC-processed aluminum alloy

TESTS

Columbus carbon forks are produced in accordance with ISO 9000. All forks are marked and their history can be traced. The tests include destruction testing and are performed on finished product samples. They are very severe:

  • Frontal and side strength test:
    A load of 200 N is first applied to the frontal part and then to the side part of the fork. The flex is measured on each occasion and this must not exceed a set value.
  • Shock Test:
    A mass of 250 N is dropped from a height of 430mm on a properly restrained fork. In order to pass the test the fork must resist without breakage or residual deformation.
  • Static Test:
    A load of 200 N is applied to the frontal part for 1 minute. In order to pass the test the fork must resist without breakage or deformation.
  • Fatigue Test:
    During this test an alternate force of +-600 N is applied. In order to pass this test the fork must resist for 150,000 cycles without breaking.
