X and XC Floating MC rotors are the lightest rotors you can buy. They will eliminate all your vibration problems and last longer than conventional rotors using round button technology. Both designs further reduce weight by up to 300 grammes by using only six drive buttons.

• X rotors feature full circle, circular rotor blades
• XC rotors feature a contoured lighter weight profile.

These rotors feature milled hard stainless steel high friction rotors for maximum braking effect, and are direct replacements for OEM rotors. These are also true fully floating units, offering more inside to outside float tolerance than any other rotor on the planet.
Do not confuse floating rotors with rotors that feature loose rotors blades or buttons. You should not be able to move either the buttons or rotor blades from side to side; if you can, it is highly likely that pad"Knock Back" will occur and you will end up with spongy brakes.
This outdated method of building rotors has now been consigned to the history books as EBC Brakes proudly announces the arrival of a new and patented design of drive button known as the SD System. Float means outside to inside heat expansion ability. That is what EBC X and XC rotors deliver and no other rotor can. SD stands for Square Drive which describes the button designs used in the new EBC X and XC rotors. EBC Brakes' unique and patented S-Drive button system features square sided rivets captured in square drive pockets on the rotor and hub which allow the outer rotor blade to expand and contract freely under the heat of braking without suffering rivet lock.

Always use new pads when replacing rotors; the use of old or worn pads can cause hot spots or glazing of the rotor, and will promote brake fade and loss of braking effort.
