• Zwift used to like ant a few years ago. Had tacx trainer + btwin hrm + btwin cadence and wheel speed sensor (an extra thing that used to help it out) on an ant dingle into a pc. Worked very reliably only occasionally it would have a tantrum.. This winter only thing thats changed is the version of Zwift. It no longer likes the cadence and wheel speed sensor so only the trainer and now use it via Bluetooth only and is finicky as hell.
    Tacx unit somehow works out cadence good enough (slower to display the actual rpm but does show same as bwtin unit does +/- 5rpm
    Ant+ seems to being dropped by many companies, either its a pita/licensing issue or bt version 4.0 and newer are just that much more stable that its not needed anymore?

  • I'm just in contact with Tacx / Garmin because my Flux has decided to not be capable of Sim mode anymore (over bluetooth at least). Since the last two Tacx firmware updates I also have to manually add Cadence option in Zwift, doesn't happen automatically.

    I also just had to replace the bearings in the freehub as it was clicking like crazy and a replacement freehub was 75EUR!
