Introducing the Mizuno Acrospeed 300! Like the best modern player's racquets, this stick features a timeless formula, combining raw speed with easy power and mindless spin. In addition to its firm and powerful beam construction, the Acrospeed 300 boasts a swingweight in the mid 320s, which keeps it stable against big hitters without sacrificing all-court speed. Factor in the spin-friendly string pattern, and you have the tools to hit a heavy ball that drops hard and explodes off the court. Technologies include a Booster Grommet system, combining alternating shapes and larger holes to increase dwell time, bite, and energy return. The Acrospeed has additional features to boost power, including an Enerzy beam construction for less deformation at impact along with a Dual Spring layup that uses resilient carbon fiber layers to return extra energy to the ball. Ultimately, the Acrospeed 300 marks a very impressive return of Mizuno to racquet manufacturing. Intermediate and advanced players looking for a powerful racquet with enough spin-potential to target the lines won't be disappointed.
