Luxilon ALU Power Spin 1.27mm Sp" Silver Set, Pentagonal Polyester for Increased Spin and Control

Luxilon ALU Power Spin 127 is a pentagonal-shaped polyester tennis string designed to increase spin and deliver precise control for aggressive baseliners.

Built from the same poly-ether-ether and aluminum composite as the classic ALU Power, this 1.27 mm shaped version adds pronounced edge geometry to bite the ball more effectively. The result is a string that keeps the precision, tension stability, and feel players expect from Luxilon while amplifying spin potential. Each set is serialized for quality tracking, and many players install it as the mains in a hybrid setup to combine spin-focused control with added power or comfort from a softer cross string.

How does the pentagonal shape improve spin on shots?

The five-sided profile increases contact friction and creates sharper edges that can grip the ball, producing more ball rotation at impact. Compared with smooth round polys, the faceted surface encourages the ball to rotate rather than skid, especially on heavy topspin strokes. This is most noticeable on high-racket-speed strokes where the string’s geometry can engage the ball fully.

• Pentagonal edges increase string-to-ball bite for added rotation.
• Faceted profile helps impart more topspin on groundstrokes and serves.
• Performs best with aggressive swing speeds and spin-oriented technique.

Will ALU Power Spin 127 give me better control without losing feel?

ALU Power Spin preserves much of ALU Power’s precise feedback thanks to the same poly-ether-ether and aluminum formula, so you get predictable feel and control. The shaped construction slightly alters the tactile sensation, making the string feel firmer at contact while still transmitting court-feel. Players who value directional accuracy and ball placement will notice improved bite with minimal compromise in touch.

• The polymer-aluminum blend maintains familiar tension behavior and responsiveness.
• Pentagonal profile yields firmer, more defined feedback on contact.
• Good for players who prioritize accuracy and shot shaping.

How should I string ALU Power Spin 127 for best performance?

Many players install ALU Power Spin as mains in a hybrid stringing pattern, pairing it with a softer or more powerful string in the crosses to balance spin with power and comfort. Tension choices depend on style: higher tensions increase control and spin feel, while slightly lower tensions add dwell and power. Use a consistent stringing technique and consider a professional stringer to preserve the pentagonal profile during installation.

• Common hybrid: ALU Power Spin mains + softer multifilament or low-modulus poly crosses.
• Higher tension for precision and spin; moderate tension for added comfort and power.
• Have a skilled stringer to prevent twisting and retain the faceted shape.

How durable is this 1.27 mm polyester compared to other strings?

At 1.27 mm, ALU Power Spin is a mid-thickness poly offering a balance between spinability and durability. The aluminum-infused polymer blend improves tension retention and resilience, but like all shaped polys it will wear faster than round thicker gauges under heavy topspin play. It performs best when rotated or replaced before fraying significantly—hybrid setups can extend usable life.

• 1.27 mm gauge balances spin and longevity for frequent spin hitters.
• Aluminum-polymer formula enhances tension stability and durability.
• Use hybrids or periodic restringing to maintain peak performance.

Who is this for: Luxilon ALU Power Spin 127 is aimed at competitive baseliners and advanced club players who want more spin and sharper control without abandoning the precise feel of ALU Power. It’s ideal as mains in a hybrid string job for those seeking a blend of aggressive rotation and reliable directional accuracy. If you routinely generate high racket head speed and focus on heavy topspin, this string set provides purposeful bite and dependable performance.
