Box One Carbon Integrated Headset 1-1/8"

Box One Carbon Integrated Headset 1-1/8"

Product Overview

The Box One Carbon Integrated Headset is a precision-engineered 1-1/8" integrated headset designed for smooth steering and durability. Featuring titanium-nitride coated sealed bearings, a carbon fiber top cap, and an expander plug system, it combines performance engineering with lightweight construction for responsive fork control.

Key Features

• Titanium-Nitride Coated Bearings — Low-friction coating reduces rolling resistance, increases corrosion resistance, and extends bearing lifespan under varied riding conditions
• Sealed 45×45 Bearings — Precision sealed design prevents dirt, water, and debris intrusion while maintaining smooth rotation and reliable performance
• Carbon Fiber Top Cap — Lightweight bearing cover reduces overall headset weight while improving aesthetics and durability
• Expander Plug System — Threaded aluminum expander eliminates the need for traditional star nuts, works reliably with standard and carbon fiber steerer tubes, and simplifies installation
• CNC-Machined Alloy Top Cap — Custom Box logo design with cut-outs reduces weight while showcasing internal components
• Split Crown Race — Allows easy installation and removal from fork crowns without damage or complications
• Anodized Hardware — Gold anodized expander plug and aluminum bolt resist corrosion and provide visual polish
