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 IS headsets are for frames with molded-in internal bearing cups. Premium Headsets with Enduro stainless steel bearings have a lifetime warranty.

Compatibility

  • Any frame that uses IS (Integrated Standard) headsets with 41mm upper and 52mm lower outer bearing diameter.
  • Uppers and lowers sold separately. 
  • Enduro stainless 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). (Never use a star nut on a carbon steerer tube).

        

Upper assembly features: 

  • Ultralight Stem Cap with Integrated Spacer plus an aluminum bolt and a star nut.
  • 7, 15, and 25mm stack height top cover options (7mm cover = 8mm total stack, 15mm cover = 15mm total stack, 25mm cover = 25mm total stack.
  • O-ring seal prevents water intrusion around steerer tube.
  • Custom-molded upper lip seal provides additional protection for upper bearing.

Lower assembly features:

  • IS lower headset consists of a bearing and crown race only. The crown race is black anodized and not visible when installed.
  • Custom over-molded dual-lip seal on the crown race to protect lower bearing in the toughest conditions.
  • Headset components precision machined in-house at Wolf Tooth from aircraft grade aluminum to ensure the highest level of quality.
  • Service and additional parts available.

Recommendations

The Wolf Tooth crown race installation adapter will help avoid damaging the crown race seals.
