This conversion kit is used to convert the driveshell and axle on any Chris King ISO hub (both Boost and non Boost). It is designed to replace your hubs current axle size. It will not allow for converting from non boost to boost.

Comes as a complete kit only which includes a new Driveshell, Axle and Adjusting Clamp design.

Previously it was possible to just swap over the Driveshell only, but due to the recent redesign of the axle (to fit the new Boost Centerlock hubs) you now require the full kit to change Driveshell.

Specifications:

- Steel Bearing
- Black or Silver Color.
- 142x12 (MicroSpline only), 148x12 or 157x12 Thru Axle.
- SRAM XD, Shimano HG or MicroSpline Driveshell.

f you are looking to just change the driveshell on the new Boost Centerlock hub you can purchase the Driveshell only .
