Question about Garmin Flux S Smart T2900S

The following cassettes are compatible with the Garmin Tacx FLUX S Smart Trainer:

- Shimano and SRAM: 8-, 9-, 10- and 11-speed cassettes. No spacer ring is required for 11- and 12-speed cassettes, while a spacer ring can be used for 8-, 9- and 10-speed cassettes.

- Separate freehub bodies are required for SRAM XD/XDR and Campagnolo cassettes and must be purchased separately.

It is important to note that no cassette is supplied with the trainer and must therefore be purchased separately.
