Convert the Superboost Centerlock hubs to fit Shimano HG, Micro Spline, or SRAM XD cassettes using Chris King's latest technology.
Gen 4 conversion kits include a pre-assembled axle, driveshell, and adjusting clamp for a plug-and-play swap. Installation requires a 2.5mm hex key and a T10 Torx tool.
This latest update to Chris King's hubs uses a Gen 4 157x12mm axle and a Gen 4 Mountain driver.
- Compatible with Superboost Centerlock hubs. Serial numbers will begin with 871
- Compatible with ISO DH Gen 2 hubs when used with a "Micro Spline" Adjusting Clamp - sold separately. Serial numbers will begin with 291
- 157x12mm axle
- Available with stainless steel or ceramic bearings
- Available in Silver or Black
- If the hub already contains a Gen 4 axle, changing cassette interfaces means only changing the driveshell
