Luxilon ALU Power 125/17 Limited Edition Tennis String

The Luxilon ALU Power 125/17 Limited Edition is the gold-standard co-polyester string used by over 60% of top 100 ATP and WTA professionals. This limited edition variant retains the legendary "Big Banger" formula—blending aluminum and fluorocarbon—but offers it in unique cosmetic finishes to match modern racquet aesthetics.

Performance Profile

1. Controlled Explosiveness: ALU Power is famous for its unique ability to provide massive "pop" (power) while maintaining a "dead" enough response that players can swing at maximum speed without the ball flying out of the court.
2. Spin Potential: While the string has a round profile, its low friction and high "snap-back" generate heavy spin, allowing for high-arching balls that drop quickly inside the lines.
3. Unique Feel: The inclusion of aluminum fibers creates a slightly crisper yet more cushioned feel compared to traditional, stiff first-generation polyesters.
4. Atmospheric Stability: The composition is completely impervious to moisture and heat, ensuring consistent performance whether playing in humid or dry conditions.

Best Suited For

1. Player Level: Advanced and competitive players. Because it is a stiff monofilament, it requires high swing speeds to "activate" the string's elastic properties.
2. Play Style: Aggressive baseliners who take full, fast cuts at the ball and need a predictable, consistent string bed.
3. Durability Seekers: Players who break synthetic gut or multifilament strings quickly but still want a lively feel.
