The front floating MC brake discs from the lightweight EBC Brakes X series have become some of the lightest and best-performing discs in the world since their introduction, and are available for all modern sports bikes. The floating MC brake discs feature EBC Brakes’ exclusive and patented S-Drive rivet system, which includes lateral square rivets allowing for the thermal expansion of the brake track, enabling it to expand and contract freely during braking without the rivets becoming locked.
