Using your Aeroe Rear Spider Cradle is easy. First, if you already have a Spider Rear Rack, it comes with one Cradle. You can add up to two more cradles to it, but remember the maximum number of cradles on one rack is three. When mounting the additional cradles, you can choose to mount them vertically or horizontally and then rotate them up to 90 degrees to make sure it fits well with your bike and your heel clearance. Once you've got the cradles in place, use the built - in nylon straps to secure your gear. This will keep the gear evenly distributed on your bike. Be careful not to exceed the recommended load capacity of 5kg per cradle. For maintenance, regularly check the nylon straps for any signs of wear and tear. If you notice any damage, replace the straps as soon as possible. Also, keep the cradles clean by wiping them down after a long ride, especially if you've been in dirty or wet conditions.
