There's no "Bursting Bubbles".
The SVT/ST spindle has an integrated caliper bracket, the non SVT/ST doesn't. The caliper mounting bracket I was refering to is part of the spindle.
The top picture is the SVT/ST Disc brake spindle with the integrated bracket, and the lower is the non-Disc bracket spindle.
