Cane Creek headset bearings feature robust, sealed cartridge designs that fit across various headset series. To replace, just select the correct bearing size and install it directly. (Refer to the compatibility chart below.) Note that compatibility with headsets from other brands is not assured. These bearings are precisely engineered by Cane Creek in Fletcher, NC.

 Notes

  • BAA2297 is a drop-in bearing upgrade kit for FSA IS42/IS52 headsets (commonly found on current Specialized mountain bikes). Designed to work with existing headset bearing cover and compression ring. Sealed crown race included.
  • BAA2191 –  49.5/40.5|52/40 – fits the 2024 Specialized World Cup.

*Our ZN40 bearings (used in all 40 Series headsets) can feel rough in hand initially. This is a necessary side effect of the corrosion-resistant zinc coating used on the balls and races. This initial roughness wears in, becoming smoother with use, and extends the overall lifespan of the bearings.
