Headsets

Original headset bearings for all Headshok and Lefty headsets when using a Lefty or Headshok. The precision machining gives it a factory tight fit again. Comes with two identical bearings for the top and bottom. Before replacing just your headset bearings, make sure that the cups are still good. Most Lefty and Headshok compatible frames had external cups that the bearing pressed into (such as the Rush, Prophet, Caffeine). Starting around 2007, many frames had integrated cups so the bearings press directly into the frame. Most Cannondale mountain frames now use the Si headtube. Kit includes two bearings. No other parts are included.
