PSB PR04 Centerlock Disc Brake Rotor

It is a whole new choice for riders that aren't satisfied with standard rotors.

Through the technology of 2D floating, the common issues of conventional rotors are effectively reduced, such as abnormal noise of the frame resonance, and the asymmetric clamping of the brake pads.

2D Floating Technology - The patented floating rivet structure on the back of the rotor is the key to the 2D floating technology, which provides PR-04's outer disc a large one-way movement space.

Floating Outer Disc - When the rotor confronts asymmetric clamping of the brake pads during braking, the floating structure activates and the outer disc adjusts itself to a proper position which both sides of the disc can withstand the same amount of wearing.

Better Performance - Besides maintaining the strength of the disc, the heat deformation caused by thermal accumulation and the abnormal noise of the frame resonance are effectively reduced during braking. Through this technology, the rotor is sufficient to meet the use of E-Bikes and has a longer service life.
