Wolftooth Premium IS52/40 Lower Headset

Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061 aluminum. They are designed to be lightweight, strong, and durable. Premium Headsets with Enduro stainless steel bearings have a lifetime warranty.

Our headsets have three levels of industry-leading custom sealing to protect bearings from the elements and prolong the life of the headset. Available in a variety of colors. These IS headsets are for frames with molded-in internal bearing cups.

COMPATIBILITY

• Any frame that uses IS (Integrated Standard) headsets with a 52mm lower outer bearing diameter.
• Uppers and lowers sold separately.
• Enduro stainless steel sealed bearings included on both the upper and lower.
• Upper headsets ship with a star nut which can only be used on forks with steel or aluminum steerer tubes. For forks with carbon steerer tubes you will need a compression plug (sold separately). (Never use a star nut on a carbon steerer tube).

FEATURES

• IS lower headset consists of a bearing and crown race only. The crown race is black anodized and not visible when installed.
• Custom over-molded dual-lip seal on the crown race to protect lower bearing in the toughest conditions.
• Headset components precision machined in-house at Wolf Tooth from aircraft grade aluminum to ensure the highest level of quality.
• Service and additional parts available.
