The Mizuno AcroSpeed 300 2026 Tennis Racket is a power-focused player's frame designed for intermediate to advanced players who want maximum ball speed without sacrificing spin. At 300g with a 100 sq in head, the AcroSpeed 300 sits in the heavier end of its category while still offering a lively, fast response — making it well suited to aggressive baseliners and big servers who want extra help generating pace on every shot.
The AcroSpeed 300 is built around Mizuno's spin and power technology stack, combining a wider sweet spot with enhanced string movement to deliver consistent performance across the hitting zone.
Technologies
- ENERZY Frame — An arched frame structure that stores and returns energy directly to the ball, enhancing power on all strokes without adding stiffness.
- Dual Spring Technology — Creates a trampoline effect at the string bed for greater energy transfer and increased ball speed across the hitting zone.
- A.B.G. (Alternate Booster Grommet) — A unique grommet hole design that alternates round and rectangular holes to improve string bite on the ball, generating extreme levels of spin.
- Booster Grommet — Rectangular hole geometry allows for larger string displacement, effectively widening the sweet spot for a more forgiving response on off-centre hits.
