VXM Road Bicycle Center lock Disc Brake Rotor Pads CNC Lighweight Aluminum Alloy MTB Bike Rotors 140mm 160mm Cycling Discs Parts

The middle lock structure ensures uniform force distribution, guaranteeing stable rotation of the disc and reducing the risk Wobble, less prone to deformation, and improved braking efficiency The external lock cover can be quickly disassembled and assembled The cylinder shaft and quick-release flower drum are universal and can be directly handled with a 44mm middle shaft wrench Installation/Disassembly Aluminum alloy + high-carbon steel Laser precision processing, quenching and hardening, the disc does not become soft, improving It has good wear resistance, is oxidized to oxygen, and is not prone to rust High-precision mirror polishing and grinding, highly flat and with great friction The brakes are sensitive and there is no abnormal noise The center is large-area hollowed-out, which reduces weight and enables rapid drainage, sewage discharge and sludge discharge Accelerate the heat dissipation performance of the disc The edges are precisely turned and hollowed out to further reduce weight And improve the heat dissipation performance
