4. Hard scratches: Significant deep scratches on the surface of bicycle accessories caused by friction with hard objects;
5. Deformation: Plane deformation of bicycle accessories caused by improper adjustment of processing equipment or internal stress of materials;
6. Dimensional deviation: Due to insufficient precision of the processing equipment, the dimensional deviation of bicycle accessories exceeds the design allowable level;
7. Uneven cutting: Due to improper positioning or equipment fixation of bicycle accessories during processing, the edges are cut unevenly;
8. Surface dents: dents formed on the metal surface due to poor heat treatment or rusting of the material, caused by internal impurities;
9. Scratches: Scratches or abrasions on the surface of bicycle accessories caused by improper protection during processing, packaging, or transportation;
10. Oxidation rust: Rust spots appear on the surface of bicycle parts due to the lack of corresponding rust prevention treatment or improper treatment measures after processing;
