The Oversize Rival is a stretch 27.5 inches long and weighs 8.9 ounces unstrung. It has a 23.5/28/25 mm dual taper beam utilizing isogrid technology with width where you need stability and power and a thinner beam for feel and spin. It is a 100% Graphite construction. This racket is balanced at 37 cm for more weight through the hit.
The HRival has consistently tested at 71 or higher on my Babolat RDC machine which would put it towards the top regarding stiffness (power) of any racket being made today.
The HRival comes with the Wilson ProFeel shock absorber pictured. Recommended String Tension is 55 to 65 lbs in this 16X20 design where I recommend going down three lbs
