"High Tension" creates tension on a rubber’s surface and sponge to use the energy of the incoming ball and redirect it back into the shot. The technology is complex, but the principle is easy to understand: Like on a trampoline, the higher tension on the surface creates a higher bounce!Rubbers using "High Tension" have a much higher surface tension compared to classic rubbers, without negatively affecting material quality. Compared to the first "High Tension" rubbers, the tension in TENERGY has even been increased by 300%. To the amazement of the Research Team, professional players also reported that Tenergy rubbers kept their high performance for a longer duration compared to other rubbers, despite the additional tension.
