Copy of Wolf Tooth Premium IS Headset - Integrated Standard - Lower - IS52/40
Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061 aluminum. They are designed to be lightweight, strong, and durable. 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. Premium Headsets with Enduro stainless steel bearings have a lifetime warranty.
- Any frame that uses IS (Integrated Standard) headsets with 41mm upper and 52mm lower outer bearing diameter.
- Uppers and lowers sold separately.
- Enduro stainless steel sealed bearings included on both the upper and lower.
- IS42 is not compatible with Specialized bikes or bikes using the Campagnolo Hiddenset standard
- 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).
