Chris King's Gen 4 conversion kit changes the freehub standard on an R45D 6-Bolt Gen 2 or R45D Centrelock hub, using a pre-assembled axle, driveshell and adjusting clamp for a plug-and-play swap — no full hub rebuild needed.

Highlights

  • Genuine Chris King Gen 4 internals — axle, driveshell and adjusting clamp pre-assembled
  • 142 x 12mm axle
  • Installs with a 2.5mm hex key and T10 Torx driver
  • Available in the Chris King colours listed below

Fitting

Chris King rates this as a straightforward freehub swap rather than a full hub service, though Tune's workshop can fit it and check bearing preload while the hub is apart.

Compatibility & fit

Fits R45D 6-Bolt Gen 2 hubs (serial numbers beginning with 6910) and all R45D Centrelock hubs (serial numbers beginning with 6710). Uses a 142 x 12mm axle.
