An Upgrade of Traditional Two-Piece Rotor
The 2D Floating Technology is the solution PSB put forward to the brake conditions of E-Bikes. Which provides the rotor a longer service life, better thermal management, and higher strength.
The patented spring rivets provide the outer disc a large movement space. When the rotor confronts asymmetric clamping of brake pads, the 2D 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.
The 2D floating technology prevents asymmetric wear between brake pads and the rotor caused by tolerance accumulation, uneven clamping, and thermal deformation from high braking temperature.
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.
Our design team and engineering team jointly developed a new solution for brake heat degradation.3D FLOATING ROTOR - PR03
