"Ceramics Plasma Electrolytic Oxidation" is an electrolytic anode surface treatment technology of advanced oxidation process combined with aluminum, magnesium and titanium alloy. With the advantages of excellent adhesion, hardness and heat resistance. Ceramics Plasma Electrolytic Oxidation is widely used in shipbuilding, national defense and aerospace industries. CRODER Cycling applied this technology into the design of the aluminum wheelset ALLEGRO 9 in 2015. This application not only creates very refreshing apperance, but also greatly improved the performance and efficiency of the brakes.
