Columbus 2020 Fork
Minimal Fork 1" or 1 1/8" non integrated
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 don’t so well complement
integrated forks. The progressive curve
of the fork blades dampens
vibrations and guarantees great handling stability
including in extreme conditions.

Columbus Expander Bung:
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.

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
- 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.
