Product description

Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061 aluminum. They are designed to be lightweight, strong, and durable. Our headsets have three levels of industry-leading custom sealing to protect bearings from the elements and prolong the life of the headset. Available in a variety of colors. These ZS headsets are for frames with internal bearing cups that are pressed into the frame.Ā 

Ā 

Compatibility

  • Any frame that uses ZS (Zero Stack) headsets with 44mm upper and 56mm lower head tube inner diameter.
  • Uppers and lowers sold separately.
  • Enduro stainless steelĀ sealed bearings included on both theĀ upper and lower.
  • Upper headsets ship with a star nut which can only be used on forks with steel or aluminum steerer tubes. For forks with carbon steerer tubes you will need a compression plugĀ (sold separately). (Never use a star nut on a carbon steerer tube).
