The Reinforced AeroBox Frame reduces drag and maintains the structural integrity of the box-type frame, for a faster swing. The High Foam System uses EVA foam inside the frame, which absorbs the shock of the shuttle and adds power. The Revolutionary Titanium T-Joint reduces twisting on off-center shots, and the ultra-thin 6 mm shaft completes the package.

A low score does not mean the racquet is bad and does not reflect its technical quality: often it is just missing data or reviews. The specs combine several sources and may have discrepancies: check the manufacturer's website and the store where you buy. ## Community 0 review(s) and comment(s) No reviews yet.
