Wolf Tooth Premium headsets are machined out of aircraft grade aluminum and feature high-end bearings made by Enduro. They are engineered to use the largest possible ball size and are filled with high-pressure waterproof lubricant. A pair of dual-lip seals ride in micro-grooves to keep out water and debris.
- Stainless steel bearings provide unparalleled corrosion resistance
- Highly recommended if your headset will be exposed to wet conditions or sweat
- Ultralight stem cap with integrated spacer, plus an aluminum bolt and a star nut
- O-ring seal prevents water intrusion around the steerer tube
- Custom-molded upper lip seal provides additional protection for upper bearing
- Lifetime warranty
