We simulate the road riding environment for product tests. We review PSB products with standards to ensure user safety.

Excellent Heat Dissipation

Aluminum centerpiece can achieve heat management. Maintain rigidity through heat treatment and keep quality accurate CNC processing.

Thickness Precision Control

The cavities of the disc is meticulously designed, so it is the key to control the thickness of the disc during the grinding stage.

     ●  Are front and rear rotors cracked or deformed ?
     ●  Does the screw or lock ring reach the recommended torque value?
  •  ●  When removing the rotor or cleaning the bike, the rotor should not be stained with oil
