I like the cadence display. I'm not good at estimating my cadence number.

I found that Zwift with the Wahoo Kickr did help my pedal stroke. The trainer is a different experience than an outdoor bike. I have to pedal more in circles instead of stabbing down. The resistance is all the way around the pedal stroke. I felt very slow on Zwift when I first started. It took 4 or 5 sessions to get used to it.

I have more power on the grades if I've been riding indoors enough. I also like that I can get a good session in just 45 minutes or so.
