Upgrade your non-integrated headtube to fit integrated headsets

With the Conversion headset from Mission, you can convert your standard 1 1/8" headtube to fit integrated headsets. The headset cups fit most 1 1/8"" frames and allow you to use integrated headset ball bearings with your frame.

  • Closed-angle ball bearings, measuring 41.8mm x 45°.
  • Keep dirt and dust out with the dust cover made of lightweight aluminum.
  • Works with both integrated and non-integrated headtubes (cups included).
