This is only the lower bearing cup, you also need the upper cup for a complete headset.

Wolf Tooth Precision Headsets are machined in the USA out of aircraft grade aluminum with superior sealing for protection against the elements. Available in a variety of colors to add some style to your bike. These EC headsets are for frames with external bearing cups. In other words, the bearing sits outside of the frame with these headsets.
