100% Guaranteed TURE FLOATING rotor. Floating means that the braking ring leg is free to pivot around the attachment pin to compensate for localized expansion of the ring and hence prevent buckling. Most manufactures use single piece rivet assembly, but in 99% of cases the necessary distortion of pin in riveting process closes the clearance between the components and hence makes the assembly fixed. With the LEGION’s patented spring-pin design the pin is NOT RIVETED, thereby guaranteeing floating action. Additionally the none-rivet assembly induces no stresses between the components and guarantees flatness.
