 Box One Carbon 45 x 45 1.5" Tapered Integrated Headset 


  • A custom CNC-machined alloy top cap in the shape of the Box logo with cut outs to reduce weight

  • 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, 45x45 bearings
  • A split crown race makes installation and removal from forks super easy
  • Box 1.5` headsets are designed solely for tapered frames and forks
