SUS410 stainless steel material, Heat dissipation and weight reduction design.

The stainless steel floating buckle design means that the outer disc is not directly locked with the hub, leaving room for expansion. Due to thermal expansion and contraction, the temperature of the center and edge of the disc brake rotor is different, and the degree of expansion is also different, resulting in internal tension. Ordinary discs will deform during intense riding movements, while the IIIPRO floating disc brake rotor uses The aluminum sheet dissipates heat and reserves expansion space, which improves the heat dissipation performance on the one hand, and solves the problem of internal tension on the other hand.
