Familiarity: I returned this product before using it
I called Wahoo to check options for using a SRAM 12 speed on my 2017 Kickr since I replaced my older bike. The support agent on the phone told me that Wahoo only makes a XDR Freehub for 2018+ Kickrs. He then suggested that if I wanted to continue using my 2017 Kickr I buy another bike!?!
Disappointing that Wahoo would strand their customers with 2 year old trainers and not invest the time to make an adapter.
