The front floating brake discs of the ultralight 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 MC floating brake discs feature the exclusive and patented EBC Brakes S-Drive rivet system, which includes lateral square rivets that allow the thermal expansion of the braking track, enabling it to expand and contract freely during braking without the rivets locking up.
