This version, like its predecessor, goes through contact with lightning speed, making it simple for players who are getting better to learn the basics of spin and pace. Yonex redesigned the frame's geometry for 2025, adding a groove on the inner part of the frame to help the racquet bend as well it can via impact and thickening the beam in the upper hoop to increase power and stability. Yonex adds ultra-thin, flexible fibers (known as Minolon) to the shaft to reduce harsh vibrations and improve comfort even more. Another invention from Yonex is 2G NAMD SPEED, an innovative substance that helps the frame give the ball greater energy. The ISOMETRIC head shape, the most significant design element, provides this stick an unquestionably more responsive and velvety feel than its traditionally formed counterparts. The EZONE 100L is still a fantastic way to experience the spin, power, and comfort of the EZONE family, thanks to some good adjustments to the feel and reaction.
