Box One Carbon Tapered Integrated Headset (1.5")

There is more to our carbon headsets than their exceptional good looks. From top to bottom, Box One™ Carbon Headsets have been designed to perform. Each unit features a custom CNC-machined alloy top cap in the shape of the Box logo w/ cut-outs to reduce weight. At the center of the top cap is an anodized aluminum bolt that threads into a gold anodized aluminum expander plug. This expander eliminates the need for a star nut & works w/ all 1 1/8-inch steerer tubes—even carbon fiber steerer tubes. The top bearing cover is crafted from carbon fiber, which not only adds style but helps to shave weight. 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 & smoother rolling bearings. A split crown race makes installation & removal from forks super easy. Box 1.5-inch headsets are designed solely for tapered frames & forks, but also include an adapter which allows you to run a fork w/ a straight 1 1/8-inch steerer tube.
