Why We Like The Premium IS42/28.6 Upper Headset Assembly

We like Wolf Tooth Components headsets for their Minnesota roots, but also because they're crafted with light and durable aircraft-grade 6061 aluminum. They're designed to be able to take a beating and last. Industry-leading custom sealing protects bearings from the elements to extend the life of the component, and we can count on a lifetime guarantee from Wolf Tooth just in case.


  • Minnesota made headsets last for a lifetime
  • 6061 Aluminum is durable and lightweight
  • Custom sealing protects bearings from the elements
  • A lifetime warranty means we don't have to go easy
