The front floating MC brake discs from EBC Brakes’ ultralight X-Series have become one 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 that allow for thermal expansion of the braking track, enabling it to expand and contract freely during braking without the rivets locking.
