Hope traditional conventional 1-1/8" straight steerer external cup headset with head doctor plug (star nut replacement). Note the original alloy head doctor plug is sheered off so a replacement bolt is in its place with a washer. or you can just use a standard star nut. The external appearance is showing typical signs of wear but is presentable enough. The bearings however while still true do feel a little notchy. Would likely be fine with a bit of decent grease on assembly but would benefit from being replaced for piece of mind. Please see pics for more detail, any questions please ask. Thanks.
