The Pyramid is a one-piece (monofilament) polyester string. The manufacturing process and the unique, triangular cross-section of the pyramid have opened up unimagined opportunities to topspin and slice players. The pleasant feeling of playing with Pyramid strings, its unique shape and its extraordinary durability are due to a second heating process, the Double Heating.
Double Heating: the Double-Heating process evens out any irregularities and eliminates internal stresses.
Pre-stretched: pre-stretching the string core or the entire string reduces the loss of tension to a minimum.
Tips for kings
Normal string tension for normal and large head sizes, normal and wide string patterns.
