You can use the Zwift Cog on the Wahoo Kickr Core, but there are a few important points to bear in mind:

- The Zwift Cog must be removed from its original freehub and mounted on the Kickr Core's freehub.
- It is necessary that the firmware of the Kickr Core is up to date to enable virtual shifting.
- Virtual shifting functionality is dependent on hardware and software compatibility, but there are reports that it is possible after the latest firmware updates.

It is advisable to follow the instructions for removing and installing the Zwift Cog on the Wahoo website or in relevant support articles.
