Excellent point about the braking isolation - shame that the review/norco did not point this out.
Also, the review glossed over the "4 bar can be made more durable" part. I would guess this is because of the two attachment points as opposed to one. But I can imagine using a large (think BB) main pivot would compensate but maybe that is heavier?
I am starting to like the idea of a horst link 4-bar with high pivot and idler.
The other thing the review failed to mention (or maybe glossed over) is that with modern wide range cassettes and 1x drivetrains, people need to be able to customize the chainring size without affecting the way the frame was designed to handle pedaling forces.
