Box Components Carbon 1-1/8 Inch Integrated Headset

There is more to our carbon headsets than their striking good looks. From top to bottom, Box One™ Carbon Headsets was designed to perform. Each unit features a custom CNC-machined aluminium compression cap in the shape of the Box logo with cut-outs to reduce weight. At the centre of the compression cap is an anodized aluminium bolt that threads into a gold anodized aluminium expander plug. This expander eliminates the need for a star nut and works with all 1-1/8-inch steerer tubes—even carbon fibre steerer tubes. The bearing cover is crafted from carbon fibre, which not only adds style but helps shave weight. And at the heart of the headset are two super-smooth, titanium-nitride coated, sealed, 45×45 bearings. The titanium coating results in a low friction coefficient, increased corrosion resistance, and smoother rolling bearings. A split crown race makes installation and removal from forks super easy.
