Axle Nut Fit Talaria MX4Features: 100% Brand New ,Never Mounted, High Quality CNC modified nuts often use special anti loosening designs to solve this problem: when the nut is screwed into the thread, the friction ring undergoes elastic deformation, tightly locking the screw thread and generating a continuous and stable frictional force (i.e. "ordinary torque"), preventing the nut from rotating and exiting on its own due to vibration The original wheel axle nuts are mostly made of steel, while CNC modified parts usually use aviation aluminum (7075 aluminum) aluminum alloy: compared with original steel parts, the weight reduction effect is obvious, and sufficient strength can be achieved through heat treatment (such as T6), making it cost-effective Quick and easy installation -- no drilling or cutting required Specification: Color: Black As Picture Material: 7075 aluminum Fitment: For TALARIA MX4 Bike Package Includes: Axle Nut As Picture Instruction of Installation is NOT Included
