MyWhoosh has just been updated and includes virtual shifting for just about any trainer unlike Zwift where it only works for very recent trainers. I’m on a circa 2018 KickR and on a 30 min ride seemed to work reasonably well. On screen controls to change gear. I think an improvement for me on mechanical shifting which with my setup has always been a bit clunky and very noisy when I get into the higher gears.
Interested to hear if others have tried it and what your thoughts are.
