Wolftooth Premium ZS44 Zero Stack Upper Headset

Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061 aluminum. They are designed to be lightweight, strong, and durable. Premium Headsets with Enduro stainless steel bearings have a lifetime 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. COMPATIBILITY

- Any frame that uses ZS (Zero Stack) headsets with 44mm upper head tube inner 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).

FEATURES

- Ultralight stem cap with integrated spacer plus an aluminum bolt and a star nut.
- 6mm top cover = 6mm total stack.
- O-ring seal prevents water intrusion around steerer tube.
- Custom-molded upper lip seal provides additional protection for upper bearing. SPECIFICATIONS
