that had been my experience with the old r453,
i agree that there is some kind of alignment issue, perhaps exacerbated by the longer cage. I would be tempted to say that the cage appears to angle out and away from perpendicular - that is if i sight up everything by eye and try to confirm with a straight edge, then id say that the bottom jockey wheel is not directly below the upper jockey wheel. its hard to judge
