Signed to reduce drag yet maintain the structural integrity of a traditional box frame, the aerobox frame results in a faster swing. The four strategic points on the frame are reinforced with a unique grommet system that strengthens the key stress points making the frame top heavy. The elasticity of the grommets allows the strings to absorb the full force from the shuttle and releases a great repulsion power during attack play.
