EC headsets are for frames with external bearing cups, which places the bearing outside of the frame with these headsets.
Premium Headsets with Enduro stainless steel bearings have a lifetime warranty.
Wolf Tooth headsets are machined in the USA with aircraft-grade 6061 aluminum. Our headsets have three levels of superior custom sealing to protect bearings from the elements and prolong the life of the headset. They are designed to be lightweight, strong, and durable.

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.
