Description: Carbon fiber bike bottle cage. Adopt plastic structure, good toughness, will not be deformed and broken under strong impact. Applicable to most mountain bikes, high strength is not easy to break, can withstand high strength pressure. The distance between the screw holes is: 55mm-72mm. Practical shape, light and stable. Both sides of the bottle holder firmly fix the bottle, and at the same time prevent scratching of the protruding part of the bottom of the bottle, ensuring that the bottle will not slide down from the bottom and will not shake. Not afraid of severe cold and heat. Combined with the characteristics of carbon fiber and plastic, it has strong toughness and is not prone to fracture and damage under low / high temperature conditions. One piece integrated moulding. Sturdy and durable, one-piece molding can effectively reduce damage, the surface has been processed, and the hardness and wear resistance have been greatly improved. Good flexibility. Rounded corners make it difficult to scratch the kettle. Good ductility. Be firm, lighter, and textured. The kettle rack has good extensibility, which makes it capable of accommodating larger-diameter kettles, and at the same time has a good clamping capacity for kettles with smaller outer diameters.
