A junior-sized version of Rafael Nadal's Babolat AeroPro Drive GT, the Babolat AeroPro Drive GT Junior has added a hybrid of braided carbon fibers and tungsten filaments throughout the entire racquet to strengthen the frame and to reduce torque for greater precision. The AeroPro Drive GT still features the vibration dampening benefits of Cortex. A great racquet for competitive juniors that are ready for a high end 26 inch racquet. This is the another option before moving into a 27 inch adult frame.
