CUTTING THE FORK STEERER TUBE AND HEADSET
SPACER INSTALLATION
Due to the front brake hose being internally routed through
the fork´s blade and steerer tube, removing the fork on
Gain requires to disconnect the front brake caliper hose.
However, it is not necessary to disconnect the front caliper
to cut the fork´s steerer tube to the desired height.
Simply disassemble the OC1 stem from the steerer tube
and remove the headset spacers (these can be split in two
halves to allow you to remove them without interfering
with the cabling).
With the fork completely inserted into the headtube and
the bike positioned so the fork is horizontally positioned
to avoid debris from falling into the headset, use a steerer
tube cutting guide and a carbon or aluminum specific saw
(depending on the steerer tube material) to cut the steerer
to the desired height. Measure the final height of all com-
ponents before cutting the steerer.
TECHN ICA L MAN UAL
When cutting, be careful not to damage any components
or cables.
The installation or removal of headset spacers does not
require to remove any cables. They are composed of two
halves that allow for easy installation without interfering
with the cabling
When installing headset spacers (30mm
maximum), make sure that the steerer tube
is long enough to allow for a correct and safe
installation of the stem and that the cables
are long enough.
Cutting the fork steerer tube requires ad-
vanced mechanical skills and must by per-
formed by a professional bicycle mechanic.
Never install headset spacers above the
stem. The steerer tube lenght must be set so
no spacers are needed above the stem.
When cutting carbon steerer tubes, make
sure the safety measures are met to avoid
inhaling carbon dust.
