    Excellent load bearing capacity at lowest weight.

    This Bobo jewelry will convince you quickly!
    What do we expect of a headset? That it works and works until you finally forget about it.Nobody is interested in the details of our precision fit, nor the quality of our ball bearings, despite the fact they’re both class leading.

    And don’t worry about whether the Gum Gum’s startnut system is carbon steerer friendly, it is. Sometimes we all need a reliable bore.
    The result: reliability, fit and forget. Low stack height and excellent load bearing ability at the lowest weight.High fitting accuracy – no loose bearings.
    Due to expander starnut mechanism – carbon steerer friendly.

    Our Ahead-cap and the GumGum expander are included.

    Available in all Tune-anodized colors here in our shop!
