Even removing the cog is impossible… QR is totally stuck, and the answer I got from Zwift Support is to use soap… Tomorrow I will go to a local store and try to solve it, but to be honest, I am totally disappointed for what I got for the money and the pointless help I got from support.

As I stated further up in the thread, your best bet is to use a vice grip shut tightly, on an angle. there is no room for slippage.
Just for the record, I had already contacted customer support before getting it off and they automatically sent me a new one, whicj I no longer need and will be sending back.

I went to a local shop store and even they weren’t able to remove it. So, I will try to get the replacement from Zwift… but for now they only told me pointless things like use soap or try stronger with the tool…

Hi All, I have the same issue with a new Zwift hub i have just purchased. Did anyone find a fix here?

Some people have successfully removed it after first removing the cassette (the Cog on the trainer)
Some have had success taking it to a bike shop for removal. Others not.
My suggestion would be to return the trainer and either roll the dice on another Zwift Hub or ask them to replace it with a Kickr Core which won’t have that problem.
Hi, apologies if this is a silly question, what size lock ring tool is needed? Thanks
The Shimano Hyperglide cassette lockring tool is the same for all. You will need a chain whip as well to remove the cog. You only need the lockring tool to reinstall it.
This is the standard shop quality lockring tool:
A cheap kit with the lockring tool and the chain whip would look like this…

The cheaper version won’t last as long.
That’s great, thanks Paul. Hopefully once the Zwift cog is removed I’ll have some success in removing this “finger tight” adapter!
Quick update - the lockring tool and chain whip worked, once the Zwift cog was removed the adapter was exposed and using a larger adjustable spanner with more leverage the adapter released. Thanks for your assistance!
