My Q is: Even though my hanger is aligned, it has been bent before a few times now. Would getting a new hanger and aligning it fix this type of shift issue? Or would I see other types of issues if hanger was the culprit?
Anything else I should try?
If it's aligned it's aligned and a new one wont improve things. I would re-confirm that its near perfect though (within 1-2mm at any point on the rim). AXS does like everything to be pretty square. I would order another one anyway though and keep your old one for an emergency spare, once they get bent a few times they can get noodly and will be prone to breaking if you need to straighten it again.
Another thing to check is the b-screw adjustment. Again it should be dead on and it must be set at sag.
