The Slazenger Challenge No.1 is a powerful hybrid-shaped racquet with an optimized weight of 355-370 grams. The 2024 model has received a range of new features to further enable and enhance the materials used in its composition, and most importantly your game. Produced with a medium density EVA core and 12K Carbon on the blade with a center balance that gives you plenty of power and speed. A longer handle increases the torque in your strokes with a more direct force from the handle, while at the same time allowing for the two-handed backhand. The AeroFen is an aerodynamic feature added to the outside of the frame, just above the grip. The air splitter cuts through the air and improves aerodynamic capabilities. Allows you to increase your swing speed. The damper reduces potential vibrations that can lead to discomfort in your playing or even injuries. The damper is made of direct injected rubber and placed in the handle. Double Tube Frame increases stability and provides support by not allowing the racquet to decompress on hard hits. The Double Tube Frame will also further increase the durability of the entire racquet. 45° 3K Carbon is crucial for the structural strength of the racquet, while also allowing more carbon to be activated with each shot. With the top layer rotated 45°, you can increase the spin and utilize the full capacity of the carbon. For all types of players who prefer a racquet with a lot of control and a lighter racquet. In addition, our panther grooves together with the 45° Carbon ensure the perfect spin.
