Luxilon ALU Power 1.25mm Tennis String, Silver, 100m Reel — Aluminium-Coated Polyester for Power and Spin

Luxilon ALU Power 125 is a tour-proven polyester tennis string delivering exceptional power, control and spin in a durable 100m silver reel.

This aluminium-coated monofilament string is a staple at the highest levels of the sport, engineered to give players a lively feel without losing precision. Offered on a 100-metre reel ideal for stringing multiple rackets or custom stringbeds, the ALU Power 125 combines Luxilon's proprietary poly-ether-ether construction with a profile tuned for aggressive players who demand consistency shot after shot.

Why do top players choose this string?

Professional players favor this model because it balances dynamic power with predictable response. Its construction preserves ball pocketing enough to produce spin while maintaining trajectory control on high-paced strokes.

• Used by approximately 60% of top-100 players on tour, indicating consistent pro-level performance
• Poly-ether-ether material provides a crisp, controlled rebound
• Aluminium coating enhances durability and spin grip
• 125 gauge offers a blend of comfort and precision suited to offensive baseliners

How does the 125 gauge affect play compared with thicker or thinner options?

The 1.25 mm diameter sits in the mid-range for polyester strings, offering a compromise between longevity and feel. It produces more spin and a livelier response than thicker gauges, while lasting longer than very thin options.

• Better spin potential than thicker gauges due to increased string movement and bite
• Improved durability relative to 1.20 mm or thinner alternatives
• Consistent tension retention for dependable control on repeated strikes

What does a 100m reel mean for recreational and club players?

A 100-metre reel supplies enough string to outfit several rackets, making it economical for coaches, clubs, and frequent stringers. It also allows players to experiment with hybrid builds or to maintain a consistent mains/ crosses setup across multiple rackets.

• Enough string for multiple full racquet sets or hybrid configurations
• Cost-effective bulk option for stringing centres and competitive players
• Individual numbering on each set portion helps track quality and batch consistency

How should I care for this polyester string to maximize life and performance?

Polyester strings perform best when kept clean and restrung before severe tension loss occurs; they don't absorb moisture but do lose tension over time and use. Store reels away from direct sunlight and extreme heat, and check tension regularly if you play often.

• Restring schedule: often between 15–40 hours of play depending on style and frequency
• Keep reel in a cool, dry place to preserve material properties
• Inspect for fraying and replace mains first if using hybrids with natural gut or multifilaments

Who is this for? Players who attack from the baseline and want reliable spin, players who string their own rackets or run a stringing service, and coaches or clubs seeking a bulk, tour-validated polyester are all well served by the Luxilon ALU Power 125 100m reel. It suits competitive club players through touring professionals who prioritize control, durability and consistent ball-snap for advanced stroke production.
