Hi, is it possible to install Zwift coq version 2 on a Zwift Hub One? I just bought the smart frame to my Zwift Hub One but it seems impossible to change the old version coq v1 with the new version included with the frame.
Yes all versions of the Cog are like an 11 speed cassette in terms of dimensions. If you bought the Cog without a freehub, I think it’s mounted on a plastic carrier that needs to be discarded before installing.
Thanks for answer. But did you have the “freehub”? When i ordered the frame it says " Zwift Cog
Single Speed Sprocket, Freehub Not Included".
When I removed the v1 coq I just have a smooth bolt on the trainer. Did you use anything from the coq 1? Maybe the “freehub” is on the coq 1 and needs to be used.
Correct, you pulled the freehub off the trainer. You need a Shimano lockring tool and a chain whip to take the cassette off the freehub. Or take the whole mess to a bike shop and they can do it in a few minutes.

Yes, of course, stupid me. Thanks. I had the whole coq 1 off, including the freehub. Now I understand I have to take it off from coq 1 and screw it back on the trainer
