The TF-X1 300 tennis racket is a next-generation racket created to boost power all while maximizing stability, tolerance and comfort. The frame ergonomics have been optimized with a rounded head size and reinforced sections for more power and stability. Isoflex technology, an all-new progressive section design, with more rigid short strings and longer long strings for the most flexible string pattern allows players to maintain speed and precision with off-centre shots. The exclusive shock absorbing technology X-Damp reduces harmful racket vibrations by up to 36%: less fatigue and more performance. With a weight of 300 g, a head size of 645 cm2 and a 16 x 20 string pattern, it is the best combination of power and spin for top-level competitors. Sold unstrung
