Chris King's new Centerlock Boost MTB hubs use a brand new axle and driveshell design which replaces the older (discontinued) version which includes the following Driveshell part numbers used to switch from say Shimano HG to SRAM XD:
These part numbers are no longer available and have been replaced with a new design of Driveshell which only works on the redesigned Boost Centerlock axle.
So if you have a Boost Centerlock rear hub and need to change from say Shimano HG to SRAM XD, you can do so with just this driveshell.
- Steel or Ceramic Bearing.
- Shimano HG, SRAM XD or MicroSpline.
- Driveshells are now all Aluminum (No stainless options) and only available in Black.
