@_Grant_Peak_Cycles and @Paul_Southworth Some backstory on the Zwift Cog variants with 18 teeth vs 14T. The tooth count does not matter for Tacx trainers, but does for Elite. Elite trainers have a higher resistance floor than other brands, and some riders find it’s too much resistance.. The 18T cog eases that resistance floor vs a 14T cog. - We try to make it as convenient as possible to install a Zwift Cog, and when possible to install it without the need to buy [a chain whip and Hyperglide cassette lockring tool](https://us.zwift.com/collections/all/products/pro-cassette-remover-set). These are bike-specific tools required to change cassettes on your rear wheel (or trainer). - The “multi trainer” 14T Zwift Cog comes preinstalled on a freehub body that fits the other Zwift Ready brands (i.e. Zwift Hub, Wahoo, JetBlack, and Van Rysel). This only requires you remove the drive-side axle adapter with a spanner you probably already own. - We offer the Zwift Cog for Eite and Tacx trainers without a freehub body because the multi-trainer FHB won’t fit those trainers anyway. Why pay for something that you can’t use? The catch here is that you’ll need a chain whip and HG cassette lockring tool to remove your cassette, and swap it for the Zwift Cog. --- _[View the full topic](https://forums.zwift.com/t/zwift-ready-compatibility-for-tacx-neo-2t-neo-2-neo-2-se-and-neo-3m-june-2025/653727)._
