EBC’s Vee-Series rotors for sport bikes are handmade in Britain using German mill-rolled precision stainless-steel rotor blades with the company’s new “VEE profile” weight reducing profile. This is mounted onto lightweight alloy center hubs using the EBC-patented SD (square drive) button technology. Square drive buttons resist loosening and prevent vibration common with low-cost circular rivets or buttons. Rotor blades are precision ground for fast and perfect pad bed-in. All EBC rotors are inspected for accuracy and runout.
