The HEAD Radical Jr. 21 is an aluminum junior racquet for kids aged 4 to 6 who want to get into the sport. It weighs 180 g unstrung, measures 21 in (53.5 cm), has a 520 cm² (81 in²) head, a 255 mm head-light balance (4 points), a constant 20 mm profile and a 16/17 string pattern. The Damp+ insert isolates the impact and reduces vibrations. The enlarged surface gives a larger sweet spot, which makes strokes more forgiving.
