I've been dealing with an issue where my front wheel is basically slanted to one side. Mechanic confirmed the wheel is dished perfectly but the dropout tolerance/alignment is not precise. We've tried few different wheels and no matter how you flip the wheel, it's tilted to the same side.
Basically the dropout on one side sits about ~1mm higher than the other side so for the wheel to sit vertically straight, the axle and the dropout needs to have a gap of 1mm to compensate on the shorter side. So what I would have to do is manually center the wheel which means on the one side, the axle is not touching the dropout and then I tighten the QR. My understanding is that the axle needs to sit in the dropouts as the QR nuts are not designed to hold wheel if it's not fully seated and my mechanic said if you put enough body weight, it will shift into the dropout and the wheel will tilt slightly again.

It's a Canyon Ultimate rim brake and Canyon has been great in replacing the fork but the new fork I got is the same issue except now it's tilted to the other side. I was told not to file anything off the fork such as the dropouts as that can compromise the integrity of the dropouts.

Canyon will be sending me another fork to try but I'm wondering if I'm chasing my own tail here? If it's an Aliexpress frame, then I'll be fine with it but spending thousands of dollars, I just want to get a fork that's symmetrical so the wheel at least sits straight.

Let me know your thoughts...My mechanic said get a new fork fork from Canyon but have them check the fork before sending out another one. Is my expectation too high? Is this something common on other brands like Trek/Specialized? I kind of feel bad for Canyon having to send out 2 replacement forks. If the next fork also has the tolerance issue I'll probably just live with it at this point.
