Gergely
Kosaka Gergely is a hybrid offensive blade designed for players who demand a potent mix of power and precision. It delivers a responsive, medium-hard feel that excels in powerful drives, heavy spins, and aggressive loops while maintaining impressive control for blocks and placement. The head-light balance enhances maneuverability, making it quick and comfortable for all-out attacking play. Suitable for a wide range, from developing players to seasoned competitors, it offers a versatile platform that pairs well with various rubber types.
The blade features a 5-ply construction with two carbon fiber layers positioned between three wood layers. This sandwich structure places the carbon near the core, enhancing overall stiffness and speed while the outer wood plies preserve ball feel and contribute to dwell time for spin generation.

✦Our expert analysis of this blade's performance characteristics
Kosaka Gergely delivers moderate to high speed, making it a potent offensive weapon. The integrated carbon layers provide a noticeable boost in power for drives and smashes. Our testing shows it leans towards an all-around offensive character rather than pure brute force, offering a speed that is aggressive yet manageable for controlled attacking rallies.
Despite its offensive pedigree, this blade offers excellent control. Players report a predictable and consistent response, allowing for accurate ball placement and the execution of delicate shots. The combination of wood and carbon, along with a supportive dwell time, helps maintain stability and precision throughout fast exchanges.
The feel is distinctly medium-hard and stiff, courtesy of the carbon layers and balsa core. However, it retains excellent sensitivity, allowing players to clearly feel ball contact. This combination provides the solid feedback needed for spin generation and control, without the completely dead sensation some stiff blades can have.
It produces a medium throw angle, which is versatile for modern attacking play. This angle offers good net clearance on opening loops and is effective for both driving through the ball and creating arc on heavy topspin shots.
Kosaka Gergely provides a medium-long dwell time. This characteristic helps the ball sink into the blade surface, giving players a slightly longer window to impart spin on loops and serves, which enhances control and spin potential.
The blade sits in the medium-stiff range for flexibility. The carbon layers provide a firm backbone, but there's enough give during powerful strokes to aid in catapult effect and spin generation, offering a more dynamic feel than an extremely rigid blade.
Vibration is minimal, contributing to a very clean and stable feel upon impact. This low vibration level aids control, especially for blocks and touch shots, by providing a solid, unfussy feedback that many offensive players prefer.
Kosaka Gergely is built with high-quality materials, resulting in a strong and durable construction. TTSensei experts note its Indonesian manufacture utilizes exported materials, delivering solid craftsmanship. While it aims to emulate top-tier models, some players find the finish and consistency may vary slightly compared to the absolute highest-end brands.
Technology
Kosaka Gergely utilizes a hybrid construction technology, sandwiching carbon fiber layers between wood plies. This design merges the natural feel and dwell time of wood with the enhanced stiffness and speed boost of carbon. Mentions of cypress outer plies and a balsa core contribute to its unique tactile response—offering sensitivity for spin and touch, while the carbon ensures a crisp, powerful rebound for aggressive shots like loops and smashes.
