What differentiates a Sauber disc brake from all others is that Suabers are impervious to rust, include radial clean out vents, and their discs and hubs are CNC machined from a single casting. The safe application, durability, and smooth operation that professionals count on while tensioning can only be achieved from completely rust free components that are designed and built specifically to the utility standards found in our All-Bronze Disc Brake.
