Chris King 2NUT™

For 14 years, if you bought a Chris King headset, you bought one of these. Chris' early reputation was built on this traditional style headset. He paired sealed bearing cups with a precision-matched adjusting & lock nut set and created a headset that could outlast a bike frame. Its durability proved itself during the rugged introduction of the mountain bike era in the late 1970s.
2Nut is the preferred headset for anyone using a threaded fork and quill stem in combination with headset spacers and/or a cable hanger. It is a popular headset with cyclocrossers and randonneurs.
After all these years, we’re happy to see custom framebuilders still selling new framesets tailor-made for the 2Nut. For some, it remains the preferred method, and we find it difficult to argue when Chris' very first headset is still going strong.
