The Black Knight Tru-Bounce double yellow dot squash ball has been developed as the result of extensive testing aimed at creating an improved double yellow dot tournament ball. This aim has been achieved using the Tru-Bounce technology which results in a double yellow dot ball delivering the same amount of speed as standard tournament balls, but surpassing them in terms of performance consistency and durability. The Black Knight Tru-Bounce is supplied in a 3-ball tube.
