Its BLX frame construction incorporates basalt, a volcanic mineral, into the Tour BLX's frame due to its anti-vibratory properties, resulting in an improved feel.
The Tour BLX's BLX frame construction uses basalt that has been manufactured into fine golden fibers woven with Wilson's Karophite Black compound which binds the basalt tightly on a molecular level, resulting in cleaner feed back and an improved feel. Additionally, the Tour BLX's 466 sq. cm/72.5 sq. in. head size, 35.7cm balance and 138g frame weight make for a more versatile racquet, suitable for beginners and experts alike.
