The BuBu is a lightweight, semi-integrated headset of elegant design and flawless functionality. The aluminum cups, crown race, and headset cover are precision machined for weight savings, and mated with quality Japanese angular contact cartridge bearings for durability.
Included with each Bubu Headset is a carbon top cap and aluminum bolt, as well as Tune's cleverly designed Gum Gum expander plug.
Note: Head set supplied without top cap
