Hi! Just picked up a new Giant Defy advanced 1 and during first ride saw that the rear cassette is wobbling. I don’t recall seeing this on my old bike. Is it something to worry about?
Cassette is shamano 11-34 with 105 di2

To add there is no play in the cassette and when it’s freewheeling it’s stable. So to me it looks like gears are not straight or something like that
Unfortunately the rear hub machining is just off. Far more common than you think. It’s probably a base level hub. Only thing you can do to fix it is to replace the rear hub. $$$
