Zwift Hub effect on w/kg

I replaced my on wheel trainer with Wahoo Sensors to a Zwift Hub. I am now crushing my PR’s on a regular basis. Was I at an big disadvantage with the earlier setup or am I now at a big advantage for reasons I don’t yet understand? How can I tell the difference? thanks.

The Zwift hub is most likely to be more accurate thank the wheel on

The accuracy between wheel on and direct drive is like night and day.

Most people find that their ftp drops dramatically when they move to a direct drive trainer.

However occasionally it works the other way.

Embrace it my friend, you’re faster than you thought!

Thanks Rich.

Thanks Stuart
