String: Sold unstrung. String Tension: ADVANCED: 21-24; EXPERT: 24-28; PRO : 28-30 Length: 67 cm Rigidity (RF): 92 EXTRA Stiff FW: 88 grams Area: 362 sq. cm. Balance: Head heavy Speed: 9.3 Power: 9.4 Frame: Blended Hex and Uni-Force frame featuring a Hex head and a unique Hex shaft and ferrule. Shaped from Super G Reactive Graphite, using BK’s Thermal Core technology. This racket is normally delivered without a grip installed, in order to best show the Uni-Force features. Characteristics: The Hex series models use Super G Reactive Graphite in a micro-woven matrix to generate faster frame recovery when flexed. The Hex frame uses its hex angularity for a stiff, aerodynamic cross-section that swings faster and hits harder. The Hex-Force 360 extends this into the unique Hex shaft. The Hex shaft has more lateral stability and resistance to torque than conventional round shafts.
