Wolf Tooth Performance Headsets are machined out of aircraft grade aluminum and assembled with Black Oxide Cartridge Bearings, balancing quality and price.

• Black Oxide Bearings are made from chromium steel for high load capacity, durability and corrision resistance
• 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
