USE OF THE HEADSET EXPANDER ON CARBON FORKS
On carbon steerer tube forks, always use an expander insi-
de the steerer tube to thread the headset compression bolt.
Never use a starnut on carbon sterer tubes. It will damage
the material and cause component failure which can lead
to serious injuries.
Consult the installation and torque settings instruction in
the expander manufacturer instructions.
