The bamboosall® has been specifically designed with all cricketers in mind. The fun safe ball also doubles as a fabulous TRAINING AID as it enhances your ability to play the moving ball as a batsman and deliver the ball correctly as a bowler. A lot of testing has gone into creating this perfect backyard ball. The bamboosall® weighs around 100 grams with a weight difference of 15 grams which creates a perfect swinging delivery when bowled correctly with the seam straight up. An average rubber ball weighs 90 grams with a tennis ball weighing approximately 65 grams. The 100 gram ball allows older players to bowl with more pace while still being safe for younger players. A dense compound rubber has been used to create similar bounce to a cricket ball. The exaggerated seam promotes spin & cut off the pitch. Bowlers are able to get a better grip on the ball and, in-turn, rip it easily. *Please BE AWARE that the bamboosall® is not suitable for beach cricket as the bounce from the dense compound rubber will be dull when the ball is wet or cold.
