There is more to the Box One Headset than its exceptional good looks. From top to bottom, it’s been designed to perform. Each headset features a custom CNC-machined alloy top cap in the shape of the Box logo. Cut outs in the logo reduce weight and show off the beauty inside. At the center of the top cap is an anodized aluminum bolt that threads into a gold anodized aluminum expander plug. The expander eliminates the need for a star nut and works with 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 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.
Bearing Angle: 45° x 45°, SHIS: IS 42/28.6 | IS 42/30, Recommended Torque: 9-10 Nm (Expander), 1.5 Nm (Top Cap)
