1.2 Disc/Rotor

100% Guaranteed TRUE 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

D-DRIVE: with the Direct Drive system the outer and inner sections are “dove-tailed” together. The unique design significantly reduces the stresses in the fixing pin and allows highly conductive aluminum to be used, improving heat transfer from the outer ring.

The Legion Discus braking rings have been designed specifically to address some of the issues associated with light weight discs, namely “pulsating” and poor lateral stiffness, and by solving these issues make them ideal for both MTB and the emerging road disc brake market.

One major issue with light-weight discs, with heavy cutouts on the braking-ring is called “pulsating” vibrations that get transmitted from the brake pads through the forks and even back to the brake lever, although not a major issue these can be annoying even on MTB but on a road set-up is totally unacceptable. This latest’s generation of braking ring eliminates this issue.

Another issue of the light-weight rotor is reduced lateral stiffness, which can lead to impaired braking due to energy being absorbed and in worse cases result in warped discs after moderate heat and braking loads. The spider pattern of the discus delivers the stiffness of a much heavier rotor but at the fraction of the weight
