Wolf Tooth Premium IS Headsets for Specialized - Integrated Standard

Wolf Tooth Premium IS Headsets for Specialized - Integrated Standard Info

Wolf Tooth Premium IS Headsets for Specialized - Integrated Standard are precision-machined in Minnesota from aircraft-grade 6061-T6 aluminum and purpose-built for Specialized frames that use molded-in internal bearing cups. Designed to be lightweight, durable, and highly resistant to contamination, this headset delivers long-term reliability with a refined finish that matches Wolf Tooth’s anodized color accents.

Engineered with three levels of custom sealing, this Premium IS headset protects the included Enduro stainless steel bearings from water, mud, and debris. An O-ring seal blocks intrusion around the steerer tube, while a custom-molded upper lip seal provides added protection for the upper bearing. The result is extended bearing life and consistent steering performance in demanding conditions.

This headset features a low-profile 3mm stack height top cover and includes an ultralight stem cap with integrated 5mm spacer, aluminum bolt, and star nut. The bearings carry a lifetime warranty, reinforcing Wolf Tooth’s commitment to durability and serviceability.
