    This piece will convince you quickly!


    What do we expect of a headset? That it works and works until you finally forget about it. Then, oobody is still interested in the precision fit, the wobbly bearings are on other bikes anyway. Not even the quality of the tune-specific angular-contact ball bearing interests. Don’t worry about whether the starnut system named Gum Gum is carbon steerer friendly: it is, after all the contact surfaces out of silicon. The result: Sometimes you need a reliable bore.

    • low build height
    • excellent load capicity at low weight
    • high precission fit, no wobble bearings
    • starnut mechanism: Gum Gum (silicone)


    The Ahead-Cap and the GumGum expander are included.
