PSB PR07 6-Bolt Disc Brake Rotor

Introducing the first single-piece rotor with floating function. With PSB's innovating 3D Floating technology, the brake heat degradation on one-piece rotors is no longer an issue. An essential upgrade for single-piece rotor enthusiasts.

Flexiblity & Rigidity - The special angle of the cut can provide support when the margin space reaches the set value along the force direction when braking. So the product strength is ensured while the floating structure restrains the high temperature deformation during braking.

Patented Elastic Disc Ribs - PSB’s PR-07 is the first one-piece disc rotor with floating function. 6 of the 12 evenly distributed ribs have patented opening cuts. The solid ribs maintain rigidity, and the open cut design truncates the rigid structure between the ribs and the outer part of the disc. So the rotor retains flexibility after fixing to the hub.

Form Follows Function - The floating function is acheived without additional part, which means without redundant weight, the ONE-PIECE FLOATER posesses a longer service life and confronts asymmetric wear during braking more effetively comparing to conventional one-piece rotors.

UCI Regulations - Referring to the UCI regulations, the outermost periphery of the disc is designed to be full round edges.
