Material: CNC aluminum axle reducer spacers are machined from quality aluminum alloy, which is lightweight, durable, and corrosion-resistant. CNC machining ensures precise dimensions and a smooth finish.. Precision Fit: CNC machining allows for tight tolerances, ensuring a precise fit between the axle and the reducer spacer. This precise fit helps maintain proper alignment and prevents any play between the axle and the hub or frame.. Compatibility: Axle adjustment spacer comes in various sizes to accommodate different axle and hubs. It is important to choose the correct size of reducer spacer that matches both the axle diameter and the hub or frame axle bore.. Installation: Installing axle adapter spacers is relatively simple. The spacers are placed on either side of the axle, between the hub bearings and the frame. Proper alignment and torque of the axle nuts or quick-release skewers are necessary to ensure secure and safe installation..
