Parents will love the Tecnifibre Bullit NW 21 Junior Tennis Racquet as a durable racquet option for their aspiring junior tennis player. The Bullits have a reinforced structure and feature 20% more durability than a standard alloy junior racquet. For protection against dings and scratches, Tecnifibre created the extense bumper which is a longer bumper guard to protect the sides of the frame. This enhancement will better protect the strings and racquet from the court. The Bullit RS 21 is 21 inches long and is suitable for play with an red ball on a 36 ft court. This racquet comes pre strung.
