Wolf Tooth Premium Headsets – Espresso

Wolf Tooth Premium Headsets – Espresso deliver precise steering performance with refined machining and a deep, understated finish that adds subtle character to any build. Designed and manufactured in Minnesota from aircraft-grade 6061 aluminum, these Zero Stack (ZS) headsets balance lightweight construction with long-term durability.

Built for frames using 44mm upper and 56mm lower internal head tube diameters, this ZS headset system features Enduro stainless steel sealed bearings in both the upper and lower assemblies. These premium bearings are backed by a lifetime warranty, providing lasting smoothness and resistance to corrosion in all-weather conditions.

Wolf Tooth integrates three levels of custom sealing to protect bearings from water, grit, and trail debris. An O-ring seal prevents intrusion around the steerer tube, while a custom-molded upper lip seal and dual-lip lower crown race seal provide added defense in demanding environments. Every component is precision-machined in-house to ensure consistent fit and finish.

The upper assembly includes an ultralight stem cap with an integrated spacer, aluminum bolt, and star nut. Note that the included star nut is for steel or aluminum steerers only—never use a star nut on a carbon steerer tube. A compression plug (sold separately) is required for carbon applications.
