Chris King InSet 3 Headset

The Chris King InSet 3 is what some folk refer to as a mixed-tapered heaset. The word mixed comes from combining (or mixing) a pressfit internal bearing upper cup with an external bearing bottom cup. The top cup features an outer diameter of 44mm while the bottom cup has a 49mm outer diameter for a 44-49mm taper. Put the two together and you get a mixed-tapered headset.

The InSet 3 fits frames that have tapered headtubes that have an inner diameter of 44mm at the top of the headtube and an inner diameter of 49mm inner diameter at the bottom of the headtube and require an external bearing cup on the bottom of the heatube. The base plate included with the InSet 3 is a 1.5" made to fit 1.5" lower steeretubes found in tapered forks.

The perfect tolerances combined with super high quality bearings make this headset function with surgical precision and rock solid durability. After all these years, this is what we have come to expect from a Chris King product. Availible in high polish black-on-black Sotto Voce graphics.
