The Carboflex 135 Airshaft is the most powerful racket in the Carboflex line. High-performance, it's perfect for amateur and occasional players looking for power. Maximum power with 500 cm² head size and Dynamix V.P. multifilament strings, it's the most powerful in the Tecnifibre line. 135 g in weight with inertia to help with heavy hits. The racket shape was redesigned by the “Airshaft” section for better aerodynamics and head acceleration. The single shaft is reinforced on the two sides with “X-Arms” tendons to limit racket flexibility and provide stability and precision on impact. To increase grip effect and tolerance against off-centre shots, the Carboflex 135 Airshaft features "Extended String hole" technology: 12 eyelets at specific spots on the frame (at 3, 9 and 12 o'clock) have been enlarged to let the strings breathe and enhance their elasticity.
