Description: Aluminum alloy material, heat dissipation, noise reduction, oxidation resistance, corrosion resistance. The material is made of rubber and synthetic abrasive, which is more wear-resistant and does not damage the rim. Widen the mud guide groove, the design of water guide and mud discharge, strengthen the adaptability of bad weather and road conditions, and increase the braking effect in rainy days. The arc design is more suitable, and the braking force is improved. The rubber block can be cleaned and replaced by removing the screw. The anti-skid texture can effectively improve the braking performance and the protection of the rim in the harsh environment.
