The Evolution top sheet with the best balance in terms of grip, coupling, optimized ball contact time, energy absorption and release was combined with a flexible, medium-hard RED ENERGY SPONGE. This newly developed sponge offers higher dynamics with a softer feel and shows its enormous potential, especially with topspin.
The result is the new EVOLUTION version FX-D, which plays noticeably differently than the equally excellent FX-P and FX-S variants and is even in the range between the high-performance EL-P in terms of performance, spin and speed values and EL-S rubbers and the top models MX-P and MX-S. This dynamic in the flexible medium-hard area is unparalleled and aims to set new standards.
