Yonex Astrox 77 Tour is a more affordable version of the Yonex Astrox 77 Pro. This racket has most of the features that the Pro variant has.
Features
1. Nanomesh Neo
Ensures a stronger more flexible frame, while increased shaft flex creates maximum power.
2. ISOMETRIC
ISOMETRIC technology continues to help the world’s greatest players achieve global success.
Developed over 30 years ago, the ISOMETRIC design increases the sweet spot by 7%*. Compared to a conventional round frame, a square-shaped ISOMETRIC racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings.
ISOMETRICTM delivers greater control without sacrificing power.
*Tested by Yonex
3. Rotational Generator System
By applying the counterbalance theory, weight is distributed throughout the grip end, frame top, and the joint for maximum control. The transition to the next shot can be performed smoothly, with rapid succession.
4. Super Slim Shaft
The slimmest racquet ever produced by Yonex vastly reduces air resistance whilst providing maximum feel.
5. Energy Boost CAP PLUS
A uniquely shaped cap that maximizes shaft performance. The front allows the shaft to flex, while the side arch-shaped curve stabilizes the racquet face by preventing the shaft from twisting.
6. Light Feel Carbon Neo
Combining gum particles with carbon fiber generates a light feel and flexibility at impact.
