What spacers would I need to put a 9 speed cassette on a kickr.
And would my wife’s sora cassette be compatible with my 9 speed ultegra found on my ritchey.
Thinking ahead. I would rather use the ritchey on the trainer, than constantly swapping cassettes.
However, might not matter. Just found out I will officially be based in either LAX or LGA, so the Ritchdy will be going where I go and staying.
