1The surface is made of 6061 aluminum alloy with high strength and light weight. 2Durable, non-deformation appearance, and uniform color, high stability in use. 3The surface adopts sandblasting technology, fine sandblasting texture is delicate, more durable in long-term use. 4Applicable to a variety of pressed-in BB shaft specifications, can meet all installation and disassembly needs (no pressed-in bowl group). 5The outer edge of the central axle is parallel to the five-way edge of the frame. Because the tool cannot be fixed in the five-way, the static pressure tool cannot be used. 6Can be removed from almost all ordinary hollow thread shaft bearings and bb86, bb30, bb91, bb30 to 24, bb92 pressure-type shaft perin installation and disassembly. 7The removal of almost all of the central axle pilling changed the common tool to remove the axle easy to damage the central axle and the problem of the frame also changed the ordinary tool can not be removed bearing. 8The surface is made of 6061 aluminum alloy with high strength and super light material, and the hardness is higher. It is light in weight, durable and non-deformation, novel in appearance, uniform in color and stability in use. 9XC/AM covers are mostly covered with mountain bikes. Anodizing will generate a layer of oxide film on the surface of aluminum, which not only has a good texture, but also effectively protects the main body of aluminum alloy. The anti-corrosion and anti-rust anodized surface adopts sandblasting technology, fine sandblasting has a fine texture, and you can use it for a long time without losing color.
