Zwift not adjusting resistance


Im using Zwift on a TACX smart flow trainer and for the last few weeks I am getting no changes in resistance at all from ZWIFT as I either climb or defend. I have made sure my trainer has the latest update and my ZWIFT app is also unto date, its so frustrating as I am having to climb in my hardest dear just to get the feeling of resistance.

I am running Zwift on a MacBook Pro with the latest operating system.


Hey Richard, we’ve been monitoring resistance issues here:

Have you had a chance to try an ANT + connection? That should get your resistance working again.

Can you please add your setup information to that topic? This will include your:

  • Your exact trainer (including the year if applicable)
  • The device you’re using to run Zwift
  • BLE or ANT+ connection?
  • Zwift Game version
  • Trainer Firmware
  • Sim or ERG mode
