Tecnifibre NRG2 17g (1.24) Black Tennis String - 40 foot pack;

One of the most popular multifilaments ever made, NRG2 goes black! Offering a slightly firmer feel than the natural color, this black version delivers world class comfort, playability and vibration dampening. The remarkable feel, at once comfortable and crisp, is achieved by combining stretchy polyurethane with powerful Elastyl fibers and an abrasion resistant coating. Used as a full set or a hybrid cross, NRG2 is second only to natural gut when it comes for comfort, power and feel.
