ABSOLUTE AB-04 2D Floating Disc Brake Rotor - Two-Piece Center Lock

2D FLOATING TECHNOLOGY The patented floating rivet structure on the back of the rotor is the key to the 2D floating technology, which provides 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.
