Good news that older Elite trainers also can use the Zwift Elite Cog.
I’m looking now for the Zwift Ride Smart Frame but you can only buy it with the standard cog and you need to buy the Elite cog seperately.
When will the grame come with the Elite cog?
The Zwift Cog for Elite trainers has 18 teeth, rather than the standard Zwift cog with 14 teeth.
The 18 tooth cog provides an easier physical gear ratio. For some riders, the Elite trainers have a high resistance “floor” in some cases. So the Elite-specific Zwift cog is recommended.
