Chris King InSet 5 Headset

The Chris King InSet 5 is identical to the InSet 3 except the outer diameter of the upper cup is 49mm to fit straight, non-tapered 49mm (1.5") headtubes. The Devo Griplock cap which slides over the upper cup and bearing reduces the diameter from 49mm to 44mm (1.5"-1 1/8") so you can use a standard tapered fork.

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.


  • Precision made and absolute reliability
  • Surgical-grade stainless steel cartridge bearings
  • 49mm internal upper bearing and 49mm external lower bearing
  • Ten-year warranty
  • 174 grams
  • Made in USA

The Chris King InSet 5 Headset will fit frames that have straight, non-tapered headtubes that have a 49mm/1.5" Inner Diameter and require an external bearing cup on the bottom of their headtube. Due to the Devo Grip lock cap that is included, the InSet 5 is meant to be used with 44-49mm/1 1/8-1.5" tapered steerer tubes. This headset may be used with straight 1-1/8" fork steerer when paired with the Chris King reducer base plate (not included).
