Zwift COG compatibility

Hi

I have a question for you.
My old Zwift Hub 11V is compatibility with Zwift COG ?
Thank’s.

Yes. You’d need to make sure the trainer firmware is up to date so it supports virtual shifting.

Thank you

Even with the COG V2 for Zwift Ride ?

Yes all the various revisions of the cog are essentially an 11 speed cassette with one sprocket. It can go on almost any trainer, so you just need a trainer that supports virtual shifting (which yours does). You do not need to buy the cog with a freehub since you already have a freehub on your trainer. You would just need a Shimano lockring tool and a chain whip to remove the old one and install the new one, or take it to a bike shop and have them do it.

Two other things that might save you a bit of time…

If you are currently using the quick-release adapters on your Hub you will need to find and install the thru-axle adapters instead. If you lost the adapters, contact Zwift support and they’ll probably give you some new ones. In some cases the quick-release adapters were installed really tight and may take some persuasion to remove.

There is a support document about installing the Cog:
