Wolf Tooth GeoShift 1d EC44 - EC44 Short
Description
EC44/28.6 UPPER - EC44/40 LOWER Headtube Length: SHORT 90 -114mm
Adjust the geometry of your bike by changing the head tube angle by 1º with the GeoShift Performance Angle Headset. It allows you to change the head tube angle by -1º to make for a slacker geometry for added stability on fast descents, or by +1º by using the opposite orientation of the headset to make for a steeper geometry for quicker steering with maximum front wheel traction.
The GeoShift Performance Angle Headset features a design in which the bearings sit at an angle that aligns with the steerer tube. This compares to angle headsets that have bearings that sit flat, which adds unneeded friction and stress on the bearings. The design with angled bearings also prevents the creaking that is common with angle headsets that feature a spherical design.
Wolf Tooth headsets are machined in the USA with lightweight, strong, durable 6061 aluminum. Our Performance Headset is built to include an Enduro black oxide coated chromium steel bearing, a one-year warranty, and three levels of superior custom sealing to protect bearings from the elements and prolong the life of the headset.
Note: the EC44 Upper/EC44 Lower is the new design of the ZS44 Upper/EC44 Lower and can be used in its stead. This new design was implemented because the constraints of a head tube with 44mm upper and lower require the upper bearing to be housed above the head tube (as opposed to inside the head tube as it was with the ZS44 upper design) for optimal performance.
Compatibility:
- 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)

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.
