Wolf Tooth headsets are machined here in our Minnesota shop with aircraft-grade 6061 aluminum. They are designed to be lightweight, strong, and durable. Premium Headsets with Enduro stainless steel bearings have a lifetime warranty. 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 EC headsets are for frames with external bearing cups, which places the bearing outside of the frame with these headsets. The EC 44 Lower cup allows for the installation of a tapered fork (1.5" - 1 1/8" steerer) on a 44mm headtube, when paired with a ZS44 upper assembly. COMPATIBILITY Any frame that uses an external cup headset with a 44mm lower head tube inner diameter. Uppers and lowers sold separately. Enduro stainless steel sealed bearings included on both the upper and lower. FEATURES Custom-molded dual-lip seal on the crown race protects lower bearing in the toughest conditions. 12.25mm stack. All components precision machined in-house at Wolf Tooth from aircraft grade aluminum to ensure the highest level of quality. Service and additional parts available.
