Bicycle Headset is a small but important part of bicycle direction system. It is a bearing assemble at head tube that connects the handlebar to the top tube of the fork, allowing it to be rotated for steering and balance purposes. Because of the protruding shape of the bearing base, so it also called a Bicycle Bowl Set.
Our Bicycle Head Set made of aluminum alloy so it has a good strength and nice regular shape, the surface is glossy and has bright color due to the good baking paint. Some shop also sells the steel Bike Headset to use on lower-end public bicycles or very cheap bikes, but will rust if gets wet or keep in humid environment.
