Isoforce 5051

The ultra carbon4 material makes the Isoforce 5051 torsionresistant. The racquet has a highly flexible shaft offering a high shot accuracy and a powerful shuttle acceleration. This racquet has several impressive technological features.

two piece

Shaft and frame are manufactured in two separate high-tech production processes, ensuring exact control of shaft flexibility and frame stiffness

ultra carb4

High-quality high modulus 40t graphite. Max. shaft momentum

balance mid

Centre of balance is close to the middle of the racket for allround balanced feel

flex high

High-flexible shaft for powerful shuttle acceleration


Rackets with the U-profile have longer than usual cross strings making the strings more elastic and the swings stronger.


Ten larger grommet holes each right and left of the inside frame make the „Mega Power Zone“. These bigger holes allow the strings to swing more freely and cause a higher rebound effect in the sweet spot area, thus yielding more power.

power waves

The wave-like shapes each right and left of the outside frame minimize the frictional string resistance where the string passes through the grommets in the frame and reduce the strain on the string. The resulting more elastic string bed provides a higher transfer of energy through the increased trampoline effect and maximizes ball acceleration by approx. 5%.

slim shaft

New slim shaft with approx. 0,5mm reduced diameter for supra-light racket weight and reduced air resistance, resulting in top handling and increased speed.

long shaft

Special, by 1cm longer shaft which is more bouncy once the shuttle is in contact with the string and which therefore provides maximum power and utmost speed.
