It is a squash racquet with a traditional head, 475 cm² (about 73.6 in²), a closed throat and a weight of 135 g. The high stiffness (RF 93) ensures controlled shots, and NCT technology, an additive in the XMG graphite fibers, reduces vibration and increases the frame's durability.

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.
