Upper Headset

Wolf Tooth Upper Headsets are machined in the USA out of aircraft grade aluminium with superior sealing for protection against the elements. Available in a variety of colours to add some style to your bike. The ZS headsets are for frames with internal bearing cups that are pressed into the frame. The EC headsets are for frames with external bearing cups. In other words, the bearing sits outside of the frame with these headsets. These IS headsets are for frames with molded-in internal bearing cups.
