The AVS SIDE  sidebar is intended to be attached directly to your bike rack.
Constructed from aluminum for enhanced durability, this sidebar is suitable for most bike racks with leg diameters ranging from 8-14mm adding AVS SIDE mounting functionality to standard racks and is easily secured with two screws.
You can add up to two AVS SIDE sidebars to a rack. Max load is 10kg on each side provided that the total load does not exceed the maximum load capacity of the primary rack itself.
