Chris King Inset i4 Silver 1.5"/49mm Frame suit 1-1/8" fork steerer GripLock
This Chris King® threadless headset features a bearing cap design called GripLock™. GripLock™ is a multi-piece bearing cap that utilizes a split ring that improves steerer tube interface.
InSet™ Model 4 with GripLock™ bearing cap is intended for 1 1-8” steerer dual crown forks, fits bikes from a number of manufacturers and is for long travel applications. As long as your bike doesn’t require an integrated headset this Inset™ headset will perform beautifully on your bike.
This Chris King® Inset™ headset is a low-stack threadless headset. Like other Chris King® headsets, it features user-serviceable stainless steel bearings. Chris King’s bearings are legendary because their design gives you years of trouble free performance with only routine maintenance.
It is absolutely essential that proper reaming and facing of your bike’s head tube be performed by a qualified mechanic during installation of this Inset™ headset. Also, please be aware that modifying a frame to make the Inset™ fit is not a proper method of installation. The proper installation of this headset is so important that you are encouraged to choose another headset if you are not able to have this Inset™ headset properly installed. We highly recommend that you carefully check your bike's specifications before ordering this headset and contact your bike manufacturer if necessary. Please note that we are unable to accept for return, exchange, or credit any headset that has been installed or has been attempted to be installed. This insures that all of our customers receive only pristine, brand new components. Thank you for your understanding. Once properly installed, this Chris King® Inset™ headset will give you years of world class performance.

Integrated headsets pose a unique challenge in that the bearings are not pressed into a cup and sit loosely in the frame. When bearings are not pressed securely into a cup they shift and move, rapidly losing preload. As preload drops, the bearings are more susceptible to creaking, damage, and failure.
Enter the patented GripLock bearing cap. The GripLock preloads the headset independently of clamping onto the steerer, so it retains preload far better than the competition and is impervious to the ill effects of load spikes from large hits and heavy braking. This means smoother steering, no more creaking, and a longer lasting headset.
GripLock design also takes the guesswork out of preloading a headset, because the bearing preload force is independent of the clamping force. Chris King headsets can be preloaded to a torque spec.

Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061-T6 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. This has a stack height of 3mm and is available in a variety of colors to match other Wolf Tooth anodized color options. These IS headsets are made exclusively for Specialized frames with molded-in internal bearing cups. Like all Wolf Tooth Premium Headsets with Enduro stainless steel bearings, the Premium IS Headset for Specialized has a lifetime warranty.
Compatibility
- Any Specialized bike that uses an IS (Integrated Standard) headset with 42mm upper 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).
- Some bikes, like the Stumpjumper EVO, have an adjustable headset that resembles a ZS headset where an upper cup is pressed into the frame. Our bearing will fit into that cup and our top cap will fit neatly on top.
