Very recently I purchased a Tacx Vortex Smart to use with Zwift. I have set it up and done a couple of rides, and when just riding along it seems to work fine. Resistance changes on the climbs. So all good there
Today I tried one of the workouts, and made sure that Erg mode was selected. However as far as I could tell, Erg mode wasn’t actually working. At one point I was in the workout and told to hold 230W. I was complying dutifully, but then I decided to test it out and start pushing the same gear at a higher cadence, in essence producing more power. I would have expected the resistance to decrease to keep me at or close to 230W, but this never happened.
Likewise when I slowed down. Power would go down, and resistance was never adjusted.
Is Erg mode with the Vortex supposed to work? I haven’t yet tested it with the Tacx app to rule out an issue on the trainer itself (will do tomorrow)
Thanks for any help
