DESIGN & TECHNOLOGY: 2G-Namd Speed graphite provides enhanced ball speed without sacrificing comfort A thicker shaft structure with a convex design reduces unwanted racquet torque on off-centered shots for added power A tapered frame design with a thinner frame face results in a softer racquet Vibration Dampening provides a stretchy mesh material is wrapped around the graphite within the grip to filter unwanted vibrations First introduced in 1969, the Oval Pressed Shaft flexes at impact to increase dwell time and minimize vibrations Compared to a conventional round frame, a square-shaped ISOMETRIC(TM) racquet generates a 7% larger sweet spot that delivers greater control without sacrificing power SPECS: HEAD SIZE: 100 in2 COLOR: Sky Blue WEIGHT: 300 g / 10.6 oz LENGTH: 27 in STRING PATTERN: 16 x 19 BALANCE: 320 mm WIDTH RANGE: 23.8 / 26.5 / 22.5 mm GRIP SIZE: 1-5 Recommended Strings: POLYTOUR PRO / POLYTOUR STRIKE / REXIS SPEED
