The Speedminton® "S-JR" junior set: train with fun and ambition The Speedminton® "S-JR" junior set is designed for kids between 6 and 12 years old. The components are adapted specifically for children and make their first steps into the sport easier as a result. Thanks to the narrow grip, the child's racquet sits comfortably in the hand, the shortened, isometric racquet shaft and the reduced weight ensure good handling. The slightly slower Fun speeders are quicker to hit with the larger hitting area. Kids will quickly feel a sense of achievement, keep improving, have lots of fun in training and show great ambition.
