TENSEI™ Pro Red 1K
Building on the foundation of its predecessor, the CK (Carbon Kevlar) Cross weave, the TENSEI™ Pro 1K series incorporates Mitsubishi Chemical’s proprietary 1K weave. This highly drapable, fabric-like material provides a smooth feel and minimizes energy loss, enhancing power transfer to the clubhead.
The Pro Red 1K series is designed to maximize distance through optimal shaft flex. It utilizes mid-section flex for powerful loading while maintaining tip stability, ensuring consistent launch angles and spin for high performance across a wide range of playing conditions.
