Robust, lightweight and long-lasting, the Cane Creek 40-Series headset for tapered steerers sets a standard for performance, durability and value with high-quality interchangeable parts.


  • ZN40 bearings are corrosion-resistant zinc-coated, machined-steel cartridge bearings with hardened steel balls, which vastly increases the longevity of the 40-series headset
  • 6061 T-6 aluminum cups and covers are internally relieved to reduce weight
  • Durable steel crown race
  • Interlok® spacer compatible (spacers not included)
  • Innovative Clip-Seal completely seals the top assembly and captures the compression ring to reduce the number of loose parts
  • High-quality, low friction face seals on the crown races
  • Designed for 1-1/8 to 1-1/2 in. tapered steerer tubes, or straight 1-1/8 in. steerers with a conversion crown race (not included)
  • External cups press into head tube
  • Integrated bearings fit directly into compatible head tubes without the need of a bearing press
  • Zero stack uppers press into head tube with very little stack height
