The Tune Bubi is a tapered 1-1/8" to 1-1/2" version of their Bubu semi-integrated headset. The Bubi is lightweight, elegantly designed, and functionally flawless. The Bubi's aluminum cups, crown race, and upper bearing cover are accurately machined for weight savings, and mated with high quality, angular contact steel cartridge bearings for durability. Included with each Bubi Headset is a carbon top cap and aluminum bolt, as well as Tune's cleverly designed Gum Gum expander plug.
The Bubi is designed for tapered headtubes with a 44mm ID upper bore, and either a 55 or 56mm ID lower bore. The 55mm lower is generally a European standard, while most American and Asian manufacturers use a 56mm lower. Please contact us if you need assistance ordering.
Tune's entire line of headsets are designed and manufactured with pride in Germany.
Installation of this headset's cups will require a headset press with appropriate adapters. The crown race is split for easy, tool-free installation. Care should be taken when fitting the delicate plastic upper bearing cover.
