Gears slipping on zwift hub

Hi there,

Does anyone have any tips on mounting your bike on a direct drive trainer so the gears aren’t all over the place. I have very smooth shifting with my back wheel in place but as soon as I drop the bike on the trainer my gears are not indexed at all. The marina issue looks like the bike won’t sit flush on the quick release properly. I have the zwift hub and I’m using the correct cassette size and quick release adapter that’s supplied. Couple of friends are using the hub and have the same issues. Any tips ???

For any more specific advice, we’d need details about your specific setup - what bike brand, model, model year, the groupset, number of cogs etc.
