Wolf Tooth Headset

EC stands for External Cup, meaning the bearing sits outside the headtube, while 44/40 refers to the specific dimensions of your headtube and fork steerer. You should measure your frame's headtube inner diameter and your fork's crown race seat diameter to ensure this lower cup is compatible with your setup.

Stainless steel is significantly more resistant to rust and corrosion than standard steel. This makes it an ideal choice for a component located near the front wheel, where it is constantly exposed to road spray, mud, and sweat.

The dual-lip seals ride in custom micro-grooves to create a physical barrier against contaminants. This design effectively prevents water, grit, and grime from reaching the internal bearings, which is why this headset is particularly well-suited for wet or harsh riding conditions.

By engineering the bearings to utilize the largest possible ball size, Wolf Tooth increases the load-bearing capacity and durability of the headset. Larger balls generally distribute force more effectively and can result in a smoother, longer-lasting steering feel.

Yes, Wolf Tooth includes a lifetime warranty on this headset. This covers defects in materials and manufacturing, giving you peace of mind that the component is built to last.
