That's a minor detail, I think Rocky got around the FSR patent by putting the pivot above the rear-centre line, so technically yes, but I'd say if the pivot is on the chainstay near the rear axle (and the brake link is floating obviously), then we categorise it as a horst link. It's gonna function more or less the same regardless of where the pivot actually is. QED, remember the older Demo where the main pivot was concentric so they could drop all the pivots, including the chainstay one? You can do something similar by raising all of them if...
