Designed to be light, strong and durable, it incorporates Wolf Tooth's stainless steel Enduro bearings to keep it rotating cleanly in a variety of conditions. These are protected by three levels of custom sealing, to keep any mud, rain or road spray firmly out. The bearings themselves are also covered by a lifetime warranty.

Wolf Tooth Premium headsets differ from the Performance range in two ways. Premium headsets feature stainless steel Enduro bearings and three top cap size options. Meanwhile Performance headsets use black oxide coated chromium steel bearings and come with a 7mm high top cap.
