Performance Zero Stack Headsets (ZS)

Wolf Tooth Components

Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061 aluminum. They are designed to be lightweight, strong, and durable.

Performance Headsets with Enduro black oxide bearings have a one-year warranty. 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. 


    • Any frame that uses ZS (Zero Stack) headsets with 44mm upper and 56mm lower head tube inner diameter.
    • Uppers and lowers sold separately.
    • Enduro black oxide steel sealed bearings included on both the 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 plug (sold separately).
