  "textContent": "The bicycle wheel (1) of the present invention is made of composite material and has two opposite braking surfaces (10), each of which is coated with a fluoride polymer layer (20). Specifically, the braking surfaces (10) are sand blasted to remove a releasing agent layer coated on the wheel (1). The wheel (1) is, thereafter, placed in a spraying machine at about 100 degree Celsius and then the braking surfaces (10) are spray-coated with a material selected from the group consisting of polytetrafluoro ethylene, fluoride ethylene-propylene copolymer, polyfluoroalkyl, ethylene-tetrafluoro ethylene copolymer and the mixture thereof until a thickness of the material is bigger than 0.4 cm. Thereafter, the wheel (1) is gradually heated to make the material set and form the fluoride polymer layers (20).",
