Wilson Steam 99 S Racquet Technologies
BL=Basalt. Basalt is a natural volcanic rock. It can be used in manufacturing where it is made into fine gold fibers with incredible vibration resistance. These new fibers are woven longitudinally with [K}arophite Black to create one of the most advanced composites in the industry.
Provides a superior, enhanced feel while increasing racquet power and reducing weight with a full Basalt expanded handle and a new shock-absorbing engineered urethane polymer. The full Basalt handle filters out unwanted vibrations and transmits a cleaner feel, giving the player a heightened sense of the ball. The specially engineered urethane absorbs some of the shock for more of an arm-friendly feel.
|Spin Effect Technology (S.E.T.)|
Using a super open 16x15 string pattern, this technology allows the main strings to deflect more for maximum snapback. The result is massive spin punctuated by balls that dive very sharply. This is the first racquet system that actually increases ball RPM without players needing to radically change their swing speed.
