Bicycle tire tread rubber is the outermost layer of bicycle tire in direct contact with the road surface, the surface with patterns of the layer of rubber, requiring the rubber to have good wear resistance, flex resistance, puncture resistance, as well as good tensile strength, tear strength, etc., generally processed with natural rubber as the main raw material; The appropriate amount of vulcanized rubber powder can not only reduce the cost of raw materials, but also improve the processing technology performance of rubber compounds, and improve the tear resistance and aging resistance of finished products.

As a key component in direct contact with the road surface, the bicycle tire tread rubber should not only adapt to different road conditions, but also protect the inner tube, which directly affects the comfort and handling of riding, and it is necessary to reasonably design the bicycle tire tread rubber E4LYY826 formula; The vulcanized rubber powder is mixed with the tread rubber rubber of the bicycle outer tire, and the formula ratio must be flexibly adjusted according to the specific performance requirements and cost control objectives, and the production process conditions must be appropriately adjusted, so as to reduce the cost of more raw materials on the premise of ensuring the performance of the tread rubber.
