The good news is my Tarmac is compatible with Kickr, unlike my 2015 Trek Domane that required a special adapter back in late 2017 (funny how history repeated itself with later Trek/Wahoo models).
The bad news is that Wahoo support just informed me that my Kickr 17 is not compatible with XDR / 12 speed cassette. Wahoo’s XDR support starts with Kickr 18 and later.
Along with InsideRide eMotion my indoor trainer setup is officially $1500 useless waste of space. Maybe I should donate it to the Smithsonian Museum?
Any workarounds that don’t involve a Shimano equipped bike, or buying another trainer?
I’m officially boycotting Wahoo. Insert NSFW finger gestures here.
