I just received the Zwift cog update kit (with the click)- nowhere in the instructions or online does it mention that the free hub installed in the cog needs to be removed to be installed on the kickr v6. There’s literally no mention of any free hub compatibility issues. It appears you can potentially remove the free hub by disassembling the cog and then installing on the kickr v6.
This seems bonkers and disingenuous let alone incompetent with regard to instructions. Additionally, as there is no documentation and I don’t have a magnifying glass- it’s impossible to notice there is a torque setting of 5nm- as I didn’t see that, I cracked the cheap plastic on the cog trying to install it.
Has anyone else encountered or worked around this? Any solutions? Does the virtual shifting even work once installed?
If you have another Shimano type cassette lockring of any kind, that should work with the Cog. Virtual shifting also works without the Cog if you want to go that route and have them mail you a replacement (ie, use your existing cassette)
There are various installation docs and videos on the Zwift website.
Same, but I have an older Kickr Core that had a cassette on it. I can remove the cassette, but to get the new Cog onto the trainer, I think I’ll have to break the Cog apart and remove the freehub. None of the videos supplied by Zwift illustrate how to do that. They assume you either want to use the version with the freehub, or that you received a version without a freehub in the first place. The latter is what I need, but it didn’t even occur to me that it existed until I found the video online. The Zwift store doesn’t say it’s out of stock or something; it’s just not there at all.
Did you get the Cog installed? I’d love some reassurance that I can break this thing open and it will still work after I slide out the freehub….
Thanks!
Tried to send this - apparently I can’t include a link but I’ll try:
Heya- after one broken cog and a ton of frustration- I did manage to get it apart and reinstalled.
This video from GP Llama was the best disassembly I found. Go to his YouTube channel and search ‘ZWIFT COG V2 Full Details…’
But you’re correct- you do have to take it apart and get the free hub out. Crazy that’s not clear in the instructions or they don’t have a non-hub option.
Just be very careful with the cog- it’s plastic and can break easily. Hand tighten the lock ring when putting it back together. If you use a tool to tighten it- be very gentle. It has a 5nm rating but I think it’s weaker.
Once I got it together- worked like a dream.
Good luck!

Thanks! I might try that. I did get the Cog onto my trainer, but I went a different route after getting some helpful comments on Reddit: using a 17mm wrench, you can loosen the nut holding the freehub onto your trainer. After you remove the nut, the freehub slides off. You’ll then have the narrower spindle that fits this version of the Cog. My only issue now is that while everything works, it’s very loud. So, I might revert to using the freehub that came originally installed on my trainer, and try your method instead.
