Using the Aeroe Spider Rear Cradle is easy. First, check if your Spider Rear Rack already has a cradle. If you want to add more, you can attach up to two extra cradles to it. You can mount these additional cradles either vertically or horizontally according to your bike's model and your needs. You can also rotate them up to 90 degrees to make sure they fit well. Once you've placed your gear on the cradle, use the built - in nylon straps to fasten it securely. Make sure the gear is evenly distributed to keep your bike balanced. As for maintenance, regularly check the nylon straps for any signs of wear and tear. If they're damaged, replace them right away. Also, clean the cradle occasionally to keep it in good condition. When not in use, store it in a dry place to prevent rusting or other damage.
