For the right headset fit: the Head Doctor headset expander by Hope
The Hope Head Doctor headset expander ensures that your headset is firmly seated. Two conical plugs are pulled together to increase the diameter of the unit and keep the plug firmly in the fork. This provides a solid thread for the attachment of the stem. The whole thing is crowned by a laser-marked cap with aluminium screw.
