Superb attacking weapon, the Yonex Astrox 88D Pro is the updated version of the Astrox 88D. The Astrox 88D Pro is an upgrade on the best-selling 88D, bringing together a head-heavy balance and stiff shaft to offer explosive attacking power. The slightly longer shaft (10mm) allows players greater reach and steeper smashes from the back court, offering unmatched power. Yonex has also introduced a wider frame width ,bigger grommet holes and its innovative Energy Boost Cap which greatly increase the feel and playability of the racket. The Energy Boost Cap especially stands out as it allows the shaft to flex, while the sides arch-shaped curve stabilizes the racquet face by preventing the shaft from twisting. This allows you to maintain control during fast rallies when you are placed under pressure .
