tune BUBI headset 55mm + GUMGUM orange

Bubi - 79 gram
Sly heads with tapered forks drive BUBI

Excellent load bearing capacity. Despite its low weight of delicate 79.0g, the strong BUBI has everything a tax rate needs.
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.

Adapter for conversion from 1,5″ Tapered to 1 1/8″ is available separately here in our shop!
The Ahead-Cap and the GumGum expander are included.

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