@tpodowd I’ve got the Kickr 2017 and long ago settled on something like 50x19 or 50x17 gearing. Today I had a long “Petit” like workout (Gibbs to be exact), and tried running 34x19 or 34x17 (not sure which) on the first 15 minute interval at 60% ftp. It was like riding on a slight decline, far too easy and nothing like a normal outdoor ride. Its hard to believe the 2017 Kickr is that much different than earlier or later models, so my question is did 34x28 feel natural?
BTW, the “catching up” part was basically the same for me on 50 ring vs 34 ring.
My conclusion today is the same as when I first bought the Kickr - the small ring is too easy and I doesn’t feel anything like riding outside.
