Constructed from high-strength 7075 T6 aluminum, these sprockets are CNC machined for superior durability and performance.\n\nThe key feature of these sprockets is the hard anodizing process. This integral surface coating significantly enhances the hardness and wear resistance of the sprocket's surface, providing extended longevity compared to standard sprockets.\n\n \n- Material: High-strength 7075 T6 aluminum\n \n- Finish: Hard anodized for increased wear resistance and durability\n \n- Design: Ultralite alloy construction for reduced weight\n \n- Pitch: 520\n \n- Teeth: 49\n
