Why We Make This: The simple answer is that many contemporary bicycle frame designs call for the headset bearings to ride inside the frame’s headtube. After decades of making press-in bearing headsets, we needed to make headsets that worked in these newer frames. From the beginning we understood that integrated headsets posed a unique challenge in that the bearings are not pressed into a cup and sit loosely in the frame. When bearings are not pressed securely into a cup they shift and move, rapidly losing preload. As preload drops, the bearings are more susceptible to creaking, damage, and failure. That’s a problem we know how to solve. Why You Want It: Enter, our patented GripLock™ bearing cap. The GripLock™ preloads the headset independently of clamping onto the steerer, so it retains preload far better than the competition and is impervious to the ill effects of load spikes from large hits and heavy braking. This means smoother steering, no more creaking, and a longer lasting headset. Our GripLock™ design also takes the guesswork out of preloading a headset, because the bearing preload force is independent of the clamping force. Our headsets can be preloaded to a torque spec.

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 aluminum compression cap in the shape of the Box logo with cut-outs to reduce weight. At the center of the compression cap is an anodized aluminum bolt that threads into a gold anodized aluminum expander plug. This expander eliminates the need for a star nut and works with all 1-1/8-inch steerer tubes—even carbon fiber steerer tubes. The bearing cover is crafted from carbon fiber, which not only adds style but helps 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, and smoother rolling bearings. A split crown race makes installation and removal from forks super easy. FEATURES - Durable Titanium-Nitride Coated Sealed Bearings - Lightweight Non-Structural Carbon Components - Reusable Expander Wedge SPECIFICATIONS - Bearing Angle: 45° x 45° - Compression Cap: CNC-Machined - Bearing Cover: Carbon Fiber - Expansion Plug: Aluminum - Compression Cap: Aluminum - Finish: TiN Bearings - IS 42/28.6 - IS 42/28.6 - Weight 94 g / 3.3 oz
