Convert your Superboost Centerlock hubs to fit Shimano HG, Micro Spline, or SRAM XD cassettes using our 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 T10 Torx tool.

This latest update to our 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 your hub already contains a Gen 4 axle, changing cassette interfaces means only changing the driveshell.
