Looking for ample storage to carry groceries, beach towels, school bags, library books and plenty of other medium-sized items? The CargoBays got you covered. Side cinch buckles on the side of the CargoBay lid allow for the top to be adjusted easily to fit your cargo needs. They can be used in combination with a SlingSet for additional carrying capacity. No need for WheelSkirts when using the CargoBays since they keep the rear wheel covered but if your bike already has WheelSKirts, you can simply install these over the skirts. Sold individually.
