Ashaway Cobra SQ 57 Racketball Racket is the easiest to use of the New Ashaway Racquetball series. With its classic string pattern and pre strung in Ashaway’s UltraKill 17 Racquetball string, this racket is fantastic for those players looking for control and feel on every shot. The softness of UltraKill 17 string, really compliments this frame. At 155g this is a popular weight with players and even with its oversize head shape, the balance of the racket is well distributed. The frame is made from the highest grade graphite (40Tonne Japanese Carbon) to make sure its owner feels at ease with its reliability and durability.
