Bicycle component

PSB BIKE INDUSTRIAL CO., LTD.

This rotor differs from conventional two-piece rotors in terms of two major features - the spring rivet structure, and the partially elastic outer disc. The outer and center parts of the disc are joined by the patented rivet structure, which also gives the outer disc space to move in the event of asymmetric clamping of brake pads. The patented open cuts are located on 6 of the 12 outer disc ribs, giving the disc flexibility. These features form the 3D floating function which can prevent safety issues caused by uneven clamping and heat deformation during braking.
