The Yonex ASTROX 77 is designed for players that want to overwhelm their opponents with speed and power. The medium flex shaft and head heavy balance help to deliver devastating power and sharp angled smashes. The ASTROX 77 Pro is the successor to the original ASTROX 77 with new materials such as FlexFuse located at the throat which helps with shock absorption and provides a softer feel. The elongated Namd shaft provides more flex to improve smashing performance.
A world-first, new dimension graphite material, Namd™, produces more flex with a faster snapback, unleashing dramatic power. (Namd™ is a technology developed by Nitta Co., Ltd.)
AERO+BOX Frame for a combination of faster swing speeds and a solid feel
By applying the counterbalance theory, weight is distributed throughout the grip end, frame top and the joint for maximum control.
Super Slim Shaft Reduced Air Resistance Designed to slice through the air, generating speedy power
Energy Boost CAP PLUS uniquely shaped cap which maximizes shaft performance
The front allows the shaft to flex, while the sides arch shaped curve stabilizes the racquet face by preventing the shaft from twisting
