Lyndall rotors are American-made and CNC machined from High Carbon Steel in California. Our rotors are made to withstand high temperatures and extreme braking situations. This allows us to lifetime guarantee our rotors (when you use Lyndall brake pads). All Lyndall rotors are three-piece floating rotors, with the outer friction ring attached to the carrier by a highly secure attachment ring, giving your rotor the flush look of a one piece rotor, with the performance benefit of a floating rotor.
