Yes I've got Stages SB20. I've not used it so much recently due to racing and hadn't fully settled into the setup. I have found no issues re power and setup -which is easy. It's built extremely well. It has dual power meters, variable crank length, dream drive or Shimano/SRAM gear shifts. Shifting is quick and drive is the quietest I've ever had. I had Wahoo , Neo
I bought it as a backup and second trainer for my gym. It was cheaper too than most others at £1599.
